Oil Pressure Sensor Replacement
What is an oil pressure sensor?
The oil pressure sensor is monitors the pressurization of the oil as it travels through the engine, and reports that pressure to the engine's computer.
How does the oil pressure sensor work?
Without the proper pressure, oil can't reach all parts of the engine or move as rapidly as it should, thus wearing it out faster. The oil pressure sensor is able to monitor this pressure and alert the computer when it drops to low. The computer can make changes to protect the engine and alert the driver of the problem.
Symptoms of a failing oil pressure switch can include:
Oil pressure warning light on
Oil pressure light flickering
Oil pressure light doesn't illuminate at all
