Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

Suggestion

I am assuming the next step is to check the o2 circuit for damage, but wanted to run tests first to see if the signal is erratic or just frozen/non-operational.

The Codes showed up probably 2000km ago maximum, but car has never had any running issues.

I only know what I know from running the line (with the engine covers off) to replace it, but I don't know so much where the black car-side plug/wire leads to.

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

Unsuccessful attempt

I replaced the driver front (Bank 1 Sensor 1) o2 sensor with a Bosch 17224, and cleared the codes with my Durametric. I drove the car close to 30km, then the code returned.

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.

1 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1Original post

I was hoping someone could help me out here, as I am not sure what steps to make next... 2009 Cayman 2.9 Car is running flawlessly, but am getting a CEL for P2231 (O2 Sensor Signal Circuit Shorted to Heater Circuit Bank 1 Sensor 1) I replaced the driver front (Bank 1 Sensor 1) o2 sensor with a Bosch 17224, and cleared the codes with my Durametric. I drove the car close to 30km, then the code returned. I cleared it a second time, and after 70km it returned. Third time, 30km again. I tried to monitor the values on the front o2, but the Durametric only has an o2 monitor for the rear o2 sensors. The o2 sensors and o2 sensor heaters have a ‘pass’ under the ready monitors. Approx 8000km ago, I had Soul long tube catted headers installed at a shop. The Codes showed up probably 2000km ago maximum, but car has never had any running issues. I am assuming the next step is to check the o2 circuit for damage, but wanted to run tests first to see if the signal is erratic or just frozen/non-operational. Also, I am currently working on jack stands, so does anyone have a diagram for the o2 sensor circuit on hand? I only know what I know from running the line (with the engine covers off) to replace it, but I don't know so much where the black car-side plug/wire leads to. Does anyone have advise as to the next steps to take? For now the car is running and driving fine, but obviously the CEL is illuminated. I'd like to try my best to remedy the issue myself before I drop it off at a shop so soon before storage, and dump 100's of dollars on diagnostics... Much appreciated!
