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.

Leading evidence: 'gas cap' (1 discussions report identifying this cause; no attributable repair resolution). Across 1 matching discussions, the most frequently mentioned possible cause is 'gas cap' (1 discussions; 1 report identifying it and 0 suggest it). The most frequently discussed action is 'Check other possible causes.(end quote)' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.

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.

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

  • Planet-9: 1 discussions

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

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

POST 1Original post

I had the P2187 (bank 1) and P2189 (bank 2) error codes come up several times after I reset them with durametrics. I was in Pin and Needles for a while. You allways think of the worst. My searches resulted in this post from a fellow at Renntech forum with the handle Loren: CEL fault code p2187 - RennTech.org Forums (quote)P2187 Oxygen Sensing Adaptation, Idle Range, Bank 1 (RKAT1) - Above Limit Possible fault cause - Incorrect main charge signal - Intake air system leaking - Fuel pressure too low - Volume supply of fuel pump too low - Mechanical fault in injection valves - PCV valve leaks - Cap of oil filler neck leaking - Leaks in exhaust system - EVAP canister purge valve mechanically faulty (hangs open) - EVAP canister purge valve output stage faults Chances are it was the gas cap. Don't worry about unless it comes back on. Then check the other possible causes.(end quote) In my particular case it turned out to be the oil filler cap was not fully closed. In the mean time I cleaned the mass air flow sensor, (Scott Slausons suggestion). I had a mechanic tell me my alternator was starting to fail, I would had to change the mass air flow sensor, the catalitic was failing, I had a leak in the exhaust. The world was comming to an end. Thank goodness it was just the oil cap. The renntech info was the best I could find on this particular error codes. I hope this post saves someone some of the anguish and grief I went through.

POST 4Original post

Thanks for the TShoot findings! How did you narrow it down to the oil cap since the code seem to focus on the fuel intake side?
