Review on Original Engine Management Oil Pressure Switch 80021 by Ronggolawe Denney

Direct replacement for 2006 Nissan Pathfinder SE. My oil pressure sensor suddenly went to the maximum pressure and stayed there with no change in the car's behavior. Stopping the car and turning it on without starting the engine showed that the pressure was still at maximum. This pretty much proved the problem was electrical and not oil pressure. Watching several videos on this symptom convinced me that the problem is with this sensor (apparently most people have a problem immediately after changing the oil) and showed me how to replace it. I would say this is one of the easiest repairs to do under a car. Luckily, the Pathfinder has enough ground clearance so you can get the job done without lifting it. The exchange went into effect immediately, and it would be a shame to pay multiple times the price of a dealer to do a job anyone with a wrench can do.
