Nissan USA
SR20DE Oil Pressure Switch

Oil began leaking somewhere from my engine, dripping down onto the right inner CV-joint, splashing around the right side undercarriage while driving, and dripping from various parts while parked. After putting the car on ramps to get a good look, I saw oil coating the electrical connector on the oil pressure sending unit - called an 'oil pressure switch' in Nissan-speak. The solution was replacement.

Purchase the following part:
