Choosing the Right Aftermarket Oil Pressure Switch

Pro Tip: Check for Leaks
When replacing the switch, check the old one for signs of oil leaking through the electrical connector. Oil leaking from the sensor body itself is a sure sign it has failed. The new switch should come with thread sealant already applied, but you can add a small amount of Teflon tape if needed.

What do the P-codes like P0520 or P0522 mean?
These are diagnostic trouble codes (DTCs) related to the oil pressure sensor circuit. P0520 indicates a general malfunction in the circuit. P0522 indicates the sensor is reading low voltage (low pressure), and P0523 indicates high voltage (high pressure). While these can point to a bad sensor, they can also be caused by wiring issues or actual oil pressure problems.
