Hi,

i have a 3500 hd , 6.5 turbo diesel.
and the SES light is on,so,had a friend read the codes,and got PO216B and P1214B.
i would like to correct it.:help:
can someone tell me what to do??

thanks Michael

p0216 is injection timing control (steeper?)
p1214 is injection pump timig offset

I'd wonder if your pump had moved and is putting the stepper in a bind.

What did your friend read the codes with, hopefully with a diagnostic scan tool and there is some more info we can use, time actual & desired would be handy, pulse width, fuel delivery, water temp, is this code active always or can it be cleared and it comes on immediately or comes back on at a certain rpm or after a period of time, happen more frequently on cold days.

The electronic IP is hard to diagnose without a scan tool & just codes, are you having any other problems or just codes, a bad PMD does not set codes but in some cases causes sympathetic codes drawing your attention to the IP when root cause is something else like something as simple as a wiring problem.

Not trying to be evasive but need additional info if you have it.

Hi TD,

he used a scan tool.
truck seems to run fine. not like my 03 with the duramax ):h
he resets the SES light, and it comes on within a few miles.
the injection pump was replaced at 80,000 miles,truck has 166,000 on it now.

thanks Michael

What kind of scan tool just a code reader or a diagnostic one like Snap On, GM tech 2, Matco, or MAC T2

Hi TD,

i think the brand was OTC.
i will ask him tommorrow.

thanks Michael

great IIRC OTC can pull some of the info we need to do some in depth recommendations

Hi Tim,

so,what should i do? should i have him hook it back to his scanner?

Michael

Yes hook it back up and pull a list of what is displayed for parameters, also see if codes can be cleared and see if they pop back on as soon as they are reset rev engine/drive truck to see if you can catch what is happening when codes set SES lite, also look in history, the 2nd & 3rd tier codes get stored there, those are things that don't set a hard code, but give some indication what might be helping to set the hard code.

Hi Tim,

he reset the light and it came back on within a mile.
i will stop there today to see if he can do it.
i do all of my own mechanical work, on my cars and trucks. i'm new to diesels.
i just started buying diesel trucks, i have a 88 with a 6.2 and i use it to plow,and i love it,i'd rather use that than my new truck with the duramax!

thanks for all the info!
Michael
