The piston cooling oil jet solenoid is located on the left side of the cylinder block, below the electric throttle. The piston cooling oil jet solenoid is located in a port in the cylinder block and sealed with an o-ring seal. A screw secures the piston cooling oil jet solenoid in the cylinder block.

The piston cooling oil jet solenoid controls the oil supply through a drilling in the cylinder block to the piston cooling oil jets. The piston cooling oil jet solenoid is a 2 stage device and controlled by the PCM  . The piston cooling oil jet solenoid can open and close the oil supply to the piston cooling oil jets depending on engine speed and load.

The piston cooling oil jet solenoid is normally open and powered closed by the PCM  . Any electrical failures in the solenoid circuitry mean that oil gets supplied to the piston cooling oil jets.
