Q: Oil light on

asked by on

The oil light is on. I suspect the PCV valve.

Hello. The PVC valve shouldn’t cause your oil light to come on. Most likely, the problem is that the oil is low, which would cause the light to come on. The oil pressure could be faulty, which would also cause the oil light to come on. It is necessary to have your car checked for oil leaks, and any possible damage that could have been done to the oil pressure switch. This can be done by a certified technician, such as one from YourMechanic.
