Leading evidence: 'Replace oxygen sensors' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Replace 4 7k ago' (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.

Reset code and drove it for 15 miles and CEL is not on.

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.

Have a code P2096 (Post Catalyst Fuel Trim System Too Lean Bank 1) with a check engine light. Is this serious and can it be ignored or reset? What is the fix? 2002 911
P2096 Signal Delay Time for Oxygen Sensor Ageing - Above Limit
Possible fault cause
- Oxygen sensor
Try clearing the code and see if it comes back. If it does, replace the oxygen sensor which is not difficult to do.
Just to be more specific, the sensor in question is the bank 1 post-cat O2 sensor. It has probably aged enough to trip the code (about slow response time of that sensor).
Yes, it's probably not that O2 sensor then. You need to run it on a scanner that shows live data and have someone that knows how to interpret it. And then go from there.
^Good question. Exhaust leak could also be a possibility. I agree with Imo that someone needs to read the O2 sensor voltage in real-time and interpret the reading.
I just had a Porsche mechanic read the computer and the only error code was the 02 sensor New cats at 91000. Reset code and drove it for 15 miles and CEL is not on.
That might not be enough for the ECU to determine if the O2 sensor is still good or not. Is the ECU done with completing the drive cycle? Readiness modes are all OK?
Dude, statistically speaking, the OP probably has sold the car by now.
And, it's highly suspect that you're affiliated with this shop when you first post is a plug for their business.
