The oil pressure light in my '02 Civic (~96K) has been randomly flickering on, for a second or less, at different speeds, road conditions, length of time in the car, etc. I have taken it to a good reputable shop and to a Honda service shop, and neither of them can pinpoint the problem. The good shop thought it might be a faulty sensor, but Honda shop guy said he’s never replaced a sensor in his career. I’ve been driving ~400 miles per week since August. I had the alternator replaced at the good shop a couple months before the oil light started flickering. The Honda shop just said that the alternator was charging too high, but they didn’t say if that was related to the oil light coming on. The battery was replaced in August, the oil level and pressure are good, and I got the oil changed two weeks ago when the good shop checked out the oil light problem.
Any suggestions for what is causing the oil light to come on??
