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

So I have a crazy gremlin going on that I can't figure out. Both lights come on randomly. Sometimes within a few blocks, sometimes within a few miles, and sometimes never. I have replaced the following: MAF, brake light sensor, fuel filter, air filter, oil change, AOS, plugs, coil packs, and tubes. I can turn off the PMS, and the ABS has yet to come on when the ABS is turned off. Has anyone experienced a bad PMS switch, or have any other ideas? Thanks in advance. 2001 Boxster Base 164k miles.

POST 2Original post

Might be a wheel speed sensor. If you can get a diagnostic tool that will read the abs system, then you should be able to tell.

I know, I know It's almost 5... but I'm just not going to.
