Whenever an oil presssure sensor is replaced on the above vehicles, a shield should also be added to protect against water intrusion. This shield is part

Parts are currently available from GMSPO.
Use the following procedure to install the shield:
1.
Disconnect the wire harness connector to the oil pressure sensor.
2.
Push the connector through the small end of the shield, and move the shield up the harness, out of the way.
3.
Reconnect the wire harness connector to the oil pressure sensor.
4.
Pull the shield over the sensor, so that the large end covers the entire sensor. The shield should fit loosely over the sensor.
5.
Use a silicon sealer, such as GM Silicone Sealant (P/N 1052915), inside the small end of the shield. Then, secure the small end of the shield to the
wire harness with a plastic tie strap. Tighten the strap as securely as possible, and cut off any excess length.

Tape the wire harness and shield with electrical tape, starting at the tie strap on the shield to the first junction in the harness.
