Due to their age the stock oil pressure sending units are notorious for fluctuating, inaccurate, and often low oil pressure readings.

Often times the connection for this sensor on the harness is bad or the connector is broken leading to erratic operation or inaccurate readings.  An affordable repair harness with a new boot is now available as an option with this sensor, or you can purchase just the terminal, connector and retainer as a kit HERE. 

Sold individually.

Fits:

• 1990-1996 Nissan 300ZX (Z32)
