Yesterday as I prepared for my weekly 3.5 hour commute on Monday morning I checked the weather as it had taken a turn for the worse in the last day going from 40 degrees with rain to freezing rain changing to snow on saturady to single digits on Sunday with strong winds. The truck was pretty much ice covered from my trip on saturday and the forecast was for 0 to sub zero temps on sunday night. So I decided to put the radiator cover on and to plug the truck in for the night in preparation for my early morning departure. I had read some of the posts about about setting off the codes using the block heater if it wasn't cold enough, but since it was predicted to go below zero I plugged it into the timer and took the chance. The truck started right up in the morning with only a momentary flash of the glow plug indicator light and no check engine light. Tranny temp stayed real low throughout the trip and engine temps stayed below 220.
Everything was fine until after about 3 hours into my trip I stopped to get a cup of coffee. I only shut it off for 5 - 10 minutes, but after restarting the truck the check engine light came on. Since the dealer that I bought the truck from was only a short diversion from the trip to my office I stopped there first. I had them pull the codes and 4 codes came up.
1) Coolant Temp sensor
2) Fuel Temp sensor
3) Air intake Sensor
4) Transmission Module Sensor.
I wasn't too surprised by the first 2 and the 3rd. The fourth surprised me. The first 2 I can relate to the problem that others have mentioned due to the block heater though I am not sure why it came on only after I stopped. The thrid might be related to running with the radiator cover on and getting a hot sensor by parking the truck and not getting enough cool air. The fourth I don't understand, but since the light came on the truck does shift differently. The symptoms are that it revs higher before shifting. It does shift, but just revs higher before shifting.
The dealer gave me 2 options.
1) Leave the light on and make an appointment for them to check out.
2) Have them reset the light and see if it comes back.
I took option #1 and have an appointment on wednesday.
Today was probably in the low to mid 30's for a high and tonight may go to 18. Back home it is supposed to go to -10. I plugged the truck in tonight as I figure I can't set off any more codes than I already have and then I don't have to let it idle as long to warm up.
What are everyone else's experiences with the LBZ with the block heater and the engine cover, I only used the radiator cover and not the bottom cover. Anyone else setting off codes in a similiar situation?
Any comments on this please let me know. Thanks.
