Oil Pressure displays 0 psi at all times
Last Updated 2 years ago
Verify the connection between the instrument and the sending unit is not shorted to ground by disconnecting the wire to the oil pressure sending unit. If this causes the oil pressure reading to read 99 psi, there is no short in this wire. If it remains at 0, this wire is shorted to ground.
If there is no short in the wire, either the oil pressure is actually 0, or the oil pressure sending unit is failed.
