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.

Suggestion
You can try clearing the code and cleaning the sensor with some of the CRC sensor cleaner spray (silver can, available in most parts stores) but the sensors have what seems like a fairly high failure rate and you will probably end up replacing it eventually.

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.

POST 1 / ORIGINAL POSTEROriginal post

Hi Guys, Anyone successfuly resolve P1123,1125 errors causing check engine light? After having the Timing tensioner replaced and ECU repaired as dealer fixed a P1321 error, the codes cleared and CEL was clear for around 150km. Now they're back and I'm not feeling too confident in the dealer now. OBD2 stats below. I have no clue what these might help point to but hoping someone on here might! Cheers, Mark === Stored Error Code(s) === Error Code: P1123 Possible Causes: Error Code: P1125 Possible Causes: Freeze Frame Information: 1. DTC for which Freeze Frame was Stored - P1123. 2. Fuel System 1 Status - Closed Loop. 3. Fuel System 2 Status - Closed Loop. 4. Calculated LOAD Value - 2.35 %. 5. Engine Coolant Temp - 190.40 °F. 6. Short Term Fuel Trim - Bank 1 - -7.03 %. 7. Long Term Fuel Trim - Bank 1 - 9.38 %. 8. Short Term Fuel Trim - Bank 2 - -10.94 %. 9. Long Term Fuel Trim - Bank 2 - 8.59 %. 10. Engine RPM - 709.00 Rpm. 11. Vehicle Speed Sensor - 0.00 Mph.

POST 2Original post

The P1123 and P1125 code pairs usually indicate a failing MAF sensor. You can try clearing the code and cleaning the sensor with some of the CRC sensor cleaner spray (silver can, available in most parts stores) but the sensors have what seems like a fairly high failure rate and you will probably end up replacing it eventually. When this happened to me, clearing the codes and cleaning the sensor would keep the check engine light off for a few thousand miles and then one or both of the codes would return. I did notice a big improvement in the way the car idled and responded to the throttle once I finally replaced the sensor.

Hellp C2951, Where can i locate the MAF in 1999 911 carrera? Please help. Thanks

Unplug the sensor (Item 3 is the sensor). Remove the two T20 security Torx screws (Item 4). Replace the sensor and tighten screws. Plug electrical connection back in.
