1994 Acura Integra 4-Vtec mileage: 81,000. I bought the car at 78,000 miles. It seems in excellent condition. I changed the oil at 81K and since then the oil light flashes intermittently, although oil is full and car drives excellent, with no engine noise. I suspect a sensor but am concerned. Any ideas or help will be appreciated.
You may have low oil pressure. With the engine off, remove the oil pressure-sending unit. Replace with a temporary mechanical oil pressure gauge. Start the engine and note pressure at idle and at 2000 RPM. At 2000 RPM, the pressure should be approximately 40 to 50 pounds and about that at idle. If you do not get these results, you may have internal engine problems. One possibility is a stuck oil pressure relief valve.
