Verified

The Check Engine Light may illuminate because of a failed knock sensor. Although the sensor often tests okay, it can fail intermittently, while the vehicle is being driven.

  • 7 months old, less than 5k miles and service engine light as well as vehicle stability system (I think that's what it's called) light came on while driving. Dealership said it was a bad camshaft sensor. Was covered under warranty but does not make me happy to have a problem with such a new car and I worry about it's reliability.

  • I took car in because I was told that the knock sensor was causing the check engine light to go on. The work was done but the light has stayed on.
