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.

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.

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

Anyway, they found no leaks either (guess I fixed it) but they did pull some codes:

POST 1 / ORIGINAL POSTEROriginal post

Howdy, I had been chasing down a vacuum leak on the 2003 Targa and changed out the regen valve on the motor. After changing it out, it ran like absolute poop - low idle even during warmup and driving it went into limp mode not able to get over 2,000 RPM. I did some smoke tests and found nothing, so I scheduled a dealer appointment. Of course the day I drove it over there it ran perfect! Would the computer need to relearn after changing the regen valve? Anyway, they found no leaks either (guess I fixed it) but they did pull some codes: Control Unit: DME P1575 Gas pedal encoder movement (inactive) (signal implausible) P0121 Drosselklappe (signal implausible) 50502: fault memory not documented (signal implausible) Control Unit: Tiptronic Fault code 24 CAN: front right wheel rpm from PSM implausible From my reading, if it's throwing these codes together it's not necessarily those sensors going, but rather MAF issues. Does that sound correct? I'd hate to $300 myself to death to find it out it's just one thing causing it. Thanks!

POST 2Original post

U need a scanner that can graph the inputs. U can store the results and review after a test drive. Clear the codes and compare the 2 front wheel sensors an the throttle position. If the codes trip again review the data to see if the signal drops out. If not it can be the maf causing the issues.
