My burb with 266K miles has the check engine light comming on with code 0753. This is apparently the second gear solenoid in the tranny. Dealer replaced the solenoid but code wouldn't clear he says due to feedback circuitry going to the ECM (PCM). It shifts fine but I don't (can't) want to spend the money to replace the ECM but need to get the truck inspected. What can I do to temperarily turn off the check engine light while I get it inspected and is there a way to repair these ECM (bad solder joints maybe) or find a cheap replacement ? One other question, are the O2 sensors the same in all positions on the exhaust system ? I believe I may have a slow O2 sensor and would like to just switch the position to see if there is a change. These are the original senors on the truck.
