Hello all. I'm having a problem with a service van. I'm getting a code P2135 Dealership charged me 910 to replace the throttle body. The very next day reduced power all the way down to an idle. After that i replaced the pedal drove it a week no problems. Gave the van to a tech. The same day i gave it to him BAM reduced engine power and P2135. Took it to gm and they said it was my obd2 gps module causing it. I dont feel confident that that is the problem. It has happened with the gps out to. Monday i will be ordering a new PCM, throttle body Harness and a Pedal Harness. I dont know what else it could be and GM Cant Figure it out either its been there multiple times. Any ideas will be tested this weekend.

 

What does code p2325 mean?
What year is the van, what model what engine.
your tags say position sensor. The camshaft position sensor went on my van, and it is in the distributor.
Need way more info.

Throttle position sensor. Ok. Have you replaced that? If not, then start there.
Why the dealership would not have done it is beyond me.

The throttle body was replaced by the dealer. I replaced the pedal. Still with no success took it to another mechanic and he could find no problems.

After replacing the computer and the harness for the throttle body and the pedal. The problem has been solved. It was the connector harness for the throttle body. Broken wire inside sheath. 22 dollar harness a little bit of time soldering and heat shrink. Total price 900 to gmc for throttle body 250 for towing 100 each the two additional mechanics that looked at it 50 for throttle pedal 250 for computer and 50 for both of the harnesses and 100 to Chevrolet to reprogram crankshaft position sensor. Grand total 1700. Word of advice start with the harness.

 

Glad to hear its fixed and thanks for posting the update.

 

It was a costly learning experience. But I have 7 more of this vans and some of the Silverados I believe I know what to look for now if I have any other problems.
