My buddies truck is having some serious issues. He called me this morning and said his truck was all messed up and was throwing an ses light and reduced engine power light. He also said it was bogging really bad. I told him I would be over after work to pull the codes and see whats up. He has an 04 Silvy eclb 5.3 2wd.

I scanned the truck and then I wonder why it didnt throw a WTF? code too! H02 heater performance and all sensors in both banks. Codes p0135,p0141,p0155, p0161. It also threw a code for a TAC Module malfuction, I dont remember if it was 1516, 2101, 2108 or 2119. I think it was 2108 though.

Anyways, what is causing all of these? I figure the h02 codes are an o2 sensor malfuction, but all 4 of them?!?!

We have had issues with his TAC in the past, do you think we should just replace it? I have a spare throttle body (DBW), should we just slap it on and see what happens or should the truck just be taken to the dealership? BTW he has had the REP light come on several times since he bought the truck.

Did he was the engine bay lately? I had some water get into my TB and I bought a new one. I'd pull the connectors and blow them out. I know I had a 1516 code I can't remember the rest (there have been so many)
