Basically, from what I could glean from my conversation with the service manager, they cleaned the sensor.

What happened in my car is : they have changed the O2 sensor first step and second step they changed ONE oil sensor, dono if it is the same thing you are talking about (cam sensor)

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.

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

POST 1 / ORIGINAL POSTEROriginal post

Last week my check engine light came on and when I took it to the dealer they diagnosed a cam tension sensor problem. Because the car has a newish sensor (I was told the same one that produced the error code) BTW, is there more than one sensor? I know there are four cams. Does that mean four sensors?) Anyway, I digress. The shop was convinced I wiped a lobe on the camshaft. They tore it down and found it to be carbon related. The camshaft and sensor were fine. Basically, from what I could glean from my conversation with the service manager, they cleaned the sensor. Is this possible? Where could the carbon come from? Would not the oil filter take care of loose carbon in the oiling system? This sounds very questionable to me. Any comments? What could or should be done to prevent this from happening again? Weird, wacky stuff.
