Scotty I have a 07 camry with 180k miles. Recently changed the transmission and had to do a zero point calibration. Now I have code p0606 for ecm processor fault. I’ve read the heated oxygen sensors can cause that. Should I fix that first?
I would have someone with a high level scan tool check the codes stored in the PCM, which at this point probably needs to be replaced and programmed.
Thanks for the reply. I’ve checked with a high level scan tool and there’s no other codes. I checked the live data and the only thing that looked weird was the data from both of the heated o2 sensors. Sometimes it would stay in a straight line and when I rev the engine the voltage would go up but when the rpms returned to normal the voltage would stay high and in a straight line
I can't find any references to heated 02 sensors causing this problem. It's pretty common for the heating element in the sensor to fry. If you want to just try replacing it, should only be about $40 or so. I am more concerned about the replacement transmission not being properly programmed to your existing PCM after installation. Something to consider.
I’m currently working on replacing the sensors right now. I’m getting oem ones that are about 100$. The one new one I’ve put in seems to be working much better. I had the transmission replaced at the dealership. It had seized up on us. For many years it would slip between 1st and 2nd gear whenever it was cold but it never had any other problems. It’s a manufacturer rebuilt one. I’ve done an all module scan and it doesn’t say anything about a loss of communication or any problems between the transmission and ecm.
Unfortunately, going to a dealership for ANYTHING is a kiss of death for your car. I wouldn't let a dealership change my windshield wipers, let alone a transmission. It sounds to me like they screwed this up and need to take responsibility for their incompetence.
