Japanese Subaru Oil Pressure Switch

Description

Watch Out for These Common Systems

There are plenty of potential signs that you need to replace your oil pressure switch. If your check engine light is on, it could be because the engine control unit has detected that the switch has stopped working. A faulty switch may be the cause of an oil leak, though there are plenty of other potential causes for oil leaks, so this warrants a close inspection under the hood. The surest way to tell that the oil pressure switch is malfunctioning is a warning light that either never turns off, or never turns on. At that point, the switch is not regulating the light according to the oil pressure.
