I was driving my duramax the other day and it sounded like it backfired. i had no power what so ever after this. still run high rpms but very little power. at an idle the engine sounds terrible. 2005 gmc duramax 2500hd 46,000 miles

codes are:

1: p0207 injector circuit open cylinder 7

2. p2146 Fuel injector grp a supply voltage circuit open

3. p0742 torque converter circuit stuck on '


If anyone knows what my problem is i would appreciate you letting me know. i wanted to talk to you guys before i went to the dealer and took a chance of them giving me the run around. oh yea if you know what my problem is can it still be corvered under the 5year 100,000 mile warranty

This sounds like injector connectors to me. GM has a TSB for this, maybe somebody here can post it for you.

Unless your dealer is real good to you I doubt if they'll do it for free but you could ask and at the same time show them the TSB. If you do a search, you might be able to find the proceedure to do it yourself if it's just the short that has happened to alot (a REAL lot) of us... It's a pretty quick and simple fix.

thanks for all yalls help. but if the wiring harness went bad in 46,000 miles and the dealer puts another one on it. won't it just go bad again in about the same amount of miles. or have they made them better.

hey i hauled my truck to the dealer yesterday and this morning they called me and said it was a fuel module. just wandering if this sounds right or not. $929.00 for the module and 130.00 for labor. they said it could not be covered under warranty cause the truck had 46000 miles

If they are talking about the FICM (fuel injector control module ) aka EDU

then its covered under federal emissions for 5/50k with 0.00 dollar deductable (all outlined in your owners manual)

It is also covered under the 5/100k mile warranty of the diesel, but once you are above the 50k mile warranty of the emissions, you have to pay 100.00 deductable (once again, all outlined in the owners manual)

Here is the document number for SI (service information) on the emissions warranty with a list of everything that is covered. Also if they claim its a wire problem, that is also covered by the emissions warranty, noted towards the bottom of the page.

Document ID# 1409367


Here is the document number for everything that is covered under the diesel warranty

Emission Control Systems Warranty

The emission warranty on your vehicle is issued in accordance with the U.S. Federal Clean Air Act. Defects in material or workmanship in GM emission parts may also be covered under the New Vehicle Limited Warranty Bumper-to-Bumper coverage. There may be additional coverage on GM diesel engine vehicles. In any case, the warranty with the broadest coverage applies.
<A href="http://service.gm.com/servlets/BlobShtml?ShtmlFile=1409367&evc=sm&pubid=972&cellId=120821&mspsdsubkey=4095#ss1-1409367">What Is Covered

The parts covered under the emission warranty are listed under "Emission Warranty Parts List" later in this section.
<A href="http://service.gm.com/servlets/BlobShtml?ShtmlFile=1409367&evc=sm&pubid=972&cellId=120821&mspsdsubkey=4095#ss2-1409367">How to Determine the Applicable Emissions Control System Warranty (Light Duty Trucks Only)

State and Federal agencies may require different emission control system warranty for light duty trucks depending on:
• Whether the truck is certified with a light duty or heavy duty emission control system.
• Whether the truck is certified for California emissions in addition to Federal emissions.
To determine emissions eligibility: locate the emission control label in the engine compartment on the air cleaner assembly or on the engine. The language on the bottom left side of the label will describe if equipped with a light, medium, or heavy duty emission control system.
All light duty trucks are eligible for Federal Emissions Control System Warranty Coverage. If the emissions control label contains language stating the vehicle is certified to California emissions standards, the vehicle is also eligible for California Emissions Control System Warranty Coverage.
<A href="http://service.gm.com/servlets/BlobShtml?ShtmlFile=1409367&evc=sm&pubid=972&cellId=120821&mspsdsubkey=4095#ss3-1409367">Federal Emission Control System Warranty


Federal Warranty Coverage

• Car and Light Duty Truck equipped with Car and Light Duty Gasoline Engines
- 2 years or 24,000 miles and 8 years or 80,000 miles for the catalytic converter or vehicle, powertrain, control module, whichever comes first.
• Light Duty Truck equipped with Heavy Duty Gasoline Engine
- 5 years or 50,000 miles, whichever comes first.
• Light Duty Truck equipped with Heavy Duty Diesel Engine
- 5 years or 50,000 miles, whichever comes first.

Federal Emission Defect Warranty
GM warrants to the owner the following:
• The vehicle was designed, equipped, and built so as to conform at the time of sale with the applicable regulations of the Federal Environmental Protection Agency (EPA).
• The vehicle is free from defects in material and workmanship which cause the vehicle to fail to conform with those regulations during the emission warranty period.
Emission related defects in the genuine GM parts listed under the Emission Warranty Parts List, including related diagnostic costs, parts, and labor are covered by this warranty.

Federal Emission Performance Warranty
Some states and/or local jurisdictions have established periodic vehicle Inspection and Maintenance (I/M) programs to encourage proper maintenance of your vehicle. If an EPA-approved I/M program is enforced in your area, you may also be eligible for Emission Performance Warranty coverage when all of the following three conditions are met:
• The vehicle has been maintained and operated in accordance with the instructions for proper maintenance and use set forth in the owner manual supplied with your vehicle.
• The vehicle fails an EPA-approved I/M test during the emission warranty period.
• The failure results, or will result, in the owner of the vehicle having to bear a penalty or other sanctions, including the denial of the right to use the vehicle, under local, state, or federal law.
GM warrants that your dealer will replace, repair, or adjust to GM specifications, at no charge to you, any of the parts listed under the "Emission Warranty Parts List" later in this section which may be necessary to conform to the applicable emission standards. Non-GM parts labeled "Certified to EPA Standards" are covered by the Federal Emission Performance Warranty.
<A href="http://service.gm.com/servlets/BlobShtml?ShtmlFile=1409367&evc=sm&pubid=972&cellId=120821&mspsdsubkey=4095#ss4-1409367">California Emission Control System Warranty

This section outlines the emission warranty that GM provides for your vehicle in accordance with the California Air Resources Board. Defects in material or workmanship in GM emission parts may also be covered under the New Vehicle Limited Warranty Bumper-to-Bumper coverage. There may be additional coverage on GM diesel engine vehicles. In any case, the warranty with the broadest coverage applies.
This warranty applies if your vehicle meets both of the following requirements:
• Your vehicle is registered in California or other states adopting California emission and warranty regulations*.
• Your vehicle is certified for sale in California as indicated on the vehicle's emission control information label.
Important: Massachusetts, Maine, and Vermont have California Emissions Warranty coverage. (New York adopted California emission standards, but not the California emissions warranty. The Federal Emissions Control Warranty applies to all vehicles in New York.)


Your Rights and Obligations (For Vehicles Subject to California Exhaust Emission Standards)
The Emission Control System Warranty on your vehicle is issued in accordance with the California Air Resources Board and GM. In California, new motor vehicles must be designed, equipped, and built to meet the state's stringent anti-smog standards. GM must warrant your vehicle's emission control system for the periods of time and mileage listed provided there has been no abuse, neglect, or improper maintenance of your vehicle. Your vehicle's emission control system may include parts such as the fuel injection system, ignition system, catalytic converter, and engine computer. Also included are hoses, belts, connectors, and other emission related assemblies.
Where a warrantable condition exists, GM will repair your vehicle at no cost to you including diagnosis, parts, and labor.

California Emission Defect and Emission Performance Warranty Coverage
For cars and trucks with light duty or medium duty emissions:
• For 3 years or 50,000 miles, whichever comes first:
- If your vehicle fails a smog check inspection, GM will make all necessary repairs and adjustments to ensure that your vehicle passes the inspection. This is your Emission Control System Performance Warranty.
- If any emission related part on your vehicle is defective, GM will repair or replace it. This is your Short-term Emission Defects Warranty.
• For 7 years or 70,000 miles whichever comes first:
- If an emission related part listed in this booklet specially noted with coverage for 7 years or 70,000 miles is defective, GM will repair or replace it. This is your Long-term Emission Control System Defects Warranty.
• For 8 years or 80,000 miles, whichever comes first:
- If the catalytic converter or vehicle, powertrain, control module is found to be defective, GM will repair or replace it under the Federal Emission Control System Warranty.
• For heavy duty gasoline engine vehicles, the emission warranty period is 5 years or 50,000 miles, whichever comes first.
• For heavy duty diesel engine vehicles, the emission warranty period is 5 years, 100,000 miles, or 3,000 hours of operation, whichever comes first.
Any authorized Chevrolet dealer will, as necessary under these warranties, replace, repair, or adjust to GM specifications any genuine GM parts that affect emissions.
The applicable warranty period shall begin on the date the vehicle is delivered to the first retail purchaser or, if the vehicle is first placed in service as a demonstrator or company vehicle prior to sale at retail, on the date the vehicle is placed in such service.

Owner's Warranty Responsibilities
As the vehicle owner, you are responsible for the performance of the scheduled maintenance listed in your owner manual. GM recommends that you retain all maintenance receipts for your vehicle, but GM cannot deny warranty coverage solely for the lack of receipts or for your failure to ensure the performance of all scheduled maintenance.
You are responsible for presenting your vehicle to a GM dealer selling your vehicle line as soon as a problem exists. The warranted repairs should be completed in a reasonable amount of time, not to exceed 30 days.
As the vehicle owner, you should also be aware that GM may deny warranty coverage if your vehicle or a part has failed due to abuse, neglect, improper or insufficient maintenance, or modifications not approved by GM.
If you have any questions regarding your rights and responsibilities under these warranties, you should contact the Customer Assistance Center at 1-800-222-1020 or, in California, write to:

The emission parts listed here are covered under the Emission Control System Warranty. The terms are explained previously in this section under the "Federal Emission Control System Warranty" and the "California Emission Control System Warranty".
Important: Certain parts may be covered beyond these warranties if shown with asterisk(s) as follows:

• (*) 7 years/70,000 miles or Super Low Emission Vehicle (SULEV) with emissions RPO code (NU3) 8 years/80,000 miles, whichever comes first, California Emission Control System Warranty coverage.
• (**) 8 years/80,000 miles, whichever comes first, Federal Emission Control System Warranty coverage. Also applies to California certified light duty and medium duty vehicles.
The Emission Control System Warranty obligations do not apply to conditions resulting from tampering, abuse, neglect, or improper maintenance; or any other item listed under "What Is Not Covered" under General Motors Corporation New Vehicle Limited Warranty (http://service.gm.com/servlets/CellHandler?CellId=72602&RefDoc=1409367&evc=sm) . The "Other Terms" presented under General Motors Corporation New Vehicle Limited Warranty (http://service.gm.com/servlets/CellHandler?CellId=72602&RefDoc=1409367&evc=sm) also apply to the emission related warranties.

Things You Should Know About the New Vehicle Limited Warranty

<A href="http://service.gm.com/servlets/BlobShtml?ShtmlFile=1110707&evc=sm&pubid=972&cellId=72605&mspsdsubkey=4095#ss1-1110707">Warranty Repairs -- Component Exchanges

In the interest of customer satisfaction, GM may offer exchange service on some vehicle components. This service is intended to reduce the amount of time your vehicle is not available for use due to repairs. Components used in exchange are service replacement parts which may be new, remanufactured, reconditioned, or repaired, depending on the component involved.
All exchange components used meet GM standards and are warranted the same as new components. Examples of the types of components that might be serviced in this fashion include: engine and transmission assemblies, instrument cluster assemblies, radios, compact disc players, tape players, batteries, and powertrain control modules.
<A href="http://service.gm.com/servlets/BlobShtml?ShtmlFile=1110707&evc=sm&pubid=972&cellId=72605&mspsdsubkey=4095#ss2-1110707">Warranty Repairs -- Recycled Materials

Environmental Protection Agency (EPA) guidelines and GM support the capture, purification, and reuse of automotive air conditioning refrigerant gases and engine coolant. As a result, any repairs GM may make to your vehicle may involve the installation of purified reclaimed refrigerant and coolant.
<A href="http://service.gm.com/servlets/BlobShtml?ShtmlFile=1110707&evc=sm&pubid=972&cellId=72605&mspsdsubkey=4095#ss3-1110707">Tire Service

Any authorized Chevrolet or tire dealer for your brand of tires can assist you with tire service. If, after contacting one of these dealers, you need further assistance or you have questions, contact Chevrolet Customer Assistance Center. The toll-free telephone numbers are listed under Owner Assistance (http://service.gm.com/servlets/CellHandler?CellId=72610&RefDoc=1110707&evc=sm) .

Call GM warranty or customer service. They will let your dealer know that it is covered under warranty. $100 deductible.

Lots of dealers do this. Don't let them con you into paying for it if you don't have to.

Cobra- is this true of the all the engine harness wiring? I noticed that wiring was on the list, how extensive is it. Stealer found charred wires when they were replacing my injector harnesses, said they had to replace the whole harness! :D Just want to make sure they are not going to hit me with the costs, cause I'll be fightin!

replace the harness? Cant say that I have ever had GM tell me do anything but repairs to the harness.

The wiring only falls under the emissions warranty, not the 5/100. Not sure what your mileage is.

I stand corrected. Thank you.:duh:

Seriously, though, the dealer would like for you to pay for the whole thing. Don't do it. Call GM or go to an honest dealer.

63,000. Had to replace the whole engine harness, said I owe $400 of the cost plus the $100 deductible. Is this fair Cobra#3747?

Cobra#3747
12-20-2006, 03:57 PM
sounds like it was probably a 50/50 split on the cost? If I had to guess. Really the wires would be out of warranty the way i read it. Not the worst case possible, gm appears to of helped some.

Is it truely fair that it failed, not really, but unfortunatly they do.

jstanton
12-20-2006, 04:16 PM
Stealer says the harness was $1953 dollars, they're only hitting me for $400. My problem is that they finally found the problem after 4 band-aid fixes. I was going to try to get them to reimburse my $600 towing bill from the last time this happened, I guess the fight continues.....
