Q: Oil Pressure Gauge

asked by on November 18, 2016

My oil pressure gauge is reading zero like it has no oil pressure at all the check engine light is on and also the check oil pressure gauge does this mean that my oil pressure sensor is bad.

My car has 107300 miles.
My car has an automatic transmission.

This light will usually come on when one of two things are happening. Either the motor is in fact low on oil or the oil pressure sending unit is not working properly and may be producing a faulty reading. I would recommend first, to check the actual oil level in the motor by using the dipstick. Be sure the oil level reaches the "full" mark. If this registers as "full" then you likely have a faulty oil pressure sending unit. I would recommend having an expert from YourMechanic come to your location to take a look at your vehicle to determine what may be causing your low oil pressure light to come on.
