DESCRIPTION

DESCRIPTION

The oil pressure sending unit uses three circuits. They are:

• A signal circuit to the Powertrain Control Module (PCM).
• A sensor ground circuit through the PCM.
• A 5 volt reference circuit from the PCM.

The oil pressure sending unit returns a voltage signal back to the PCM relating oil pressure. Ground for the sensor is supplied by the PCM.

The oil pressure switch (1) is located on the right side of the engine block. The switch screws into the engines main oil gallery.
