Why is my oil pressure sensor at zero?
Why is my oil pressure sensor at zero? Oil pressure gauge is at zero Most older cars have an actual mechanical gauge that gives the driver a readout on the oil pressure. If this gauge is reading zero even when oil levels are where they need to be, then the oil pressure sensor is probably to blame. Modern cars that have a oil pressure gauge use an electronic signal. Why does my oil pressure go to 0 and back up? Dropping to 0 and back up is likely either an intermittent wiring problem in the oil sending unit or the...
