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.

Yeah saw this on various threads (reccomendation was to clean the sensor) and discounted as it came on without moving the car...Also a reset of codes with Durametic and restart didn't resolve the problem...Weekend job is to lift her up and go over all the ABS sensors

Ordered a replacement sensor from Pelican and will replace anyway, but if I am honest I was surprised an AFM sensor change worked for a PSM failure and it wasn't an ABS wheel sensor or ring problem, but it is all in and working again.

After driving the car last weekend with no issues, when I jumped in to start the car this morning the dash lit up with error lights for PSM and ABS as well as had a strange RPM drop on startup and running extremely rich.

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.

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

POST 1 / ORIGINAL POSTEROriginal post

Just wanted to put this up in case anyone else runs into the same issue After driving the car last weekend with no issues, when I jumped in to start the car this morning the dash lit up with error lights for PSM and ABS as well as had a strange RPM drop on startup and running extremely rich. After finishing work and delving into it via GOOGLE it seems that the two (2) primary causes are: Broken brake light switch - This can be checked and discoutned if the brake lights work properly AFM Error - Pulled the Durametic and read a number of errors including ABS/PSM as well as DME codes. Thsi aligned with the AFM errors others noted online. Luckily I had previously bought a complete 2nd hand 997 airbox that included a AFM sensor. Cleaned using AFM cleaner and installed the complete air box, cleared the code with Durametic and its all back to normal. Ordered a replacement sensor from Pelican and will replace anyway, but if I am honest I was surprised an AFM sensor change worked for a PSM failure and it wasn't an ABS wheel sensor or ring problem, but it is all in and working again.

POST 2Original post

Quotes source post: 349005

Just as an FYI, something I occasionally struck with my 6.2 C2 was an ABS error caused by a front wheel lifting (eg coming out of a service station driveway at an angle, causing a wheel to lift). This seemed to confuse the system resulting in an ABS error. Solution was to turn the ignition off and restart....
