If so then check to see if Rodents ate your wiring to the sensor......and/or test for 12v power to the sensor , and get the diagram and check the fuse ...

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Hi everyone, bought an used C4S. i have a Check Engine and it�s P0056 and P0161. i changed both sensor and still have issues. any ideas?

POST 3Original post

Need something like Durometric to read the codes. Chances are you have another problem. I eventually found and intake gasket leak- after that all was great. No codes and it smoged like an electric motor.

POST 4 / ORIGINAL POSTEROriginal post

Thank you. I do have an air leak from my oil filler tube that is craked. We did check and all the wire is right. I do have a Bank "2" Sensor "2" but we changed both

POST 6 / ORIGINAL POSTEROriginal post

Do you guys think this can be an ECU issue too?

POST 7Original post

Quotes source post: 20192869

Most likely no. But the wiring to the computer or o2 itself along with the pins in the dme plug could all be an issue. Understanding and diangnostic with a multumeter is the only way to find the issue

POST 8 / ORIGINAL POSTEROriginal post

Anybody used ECU Doctor in FL? I think of sending my ECU to remove the sensor because i still have this issue

POST 9Original post

I had to screw around with this recently and was able to figure it out. First, make sure your sensors are not installed backwards. Then I would take the plug and check (i think it's a black wire) and ensure you're getting 12v to it. Ignition has to be on. otherwise you'll get a false positive. If that's all good, then take the plug from the sensor side and confirm that you have appropriate resistance between the 2 white wires. That's for the heating element. This is what a reading looked like for me for a working sensor. If you're in the 2-3ohm range then that's a sensor issue. As as other said, check your wiring.
