- Check the actual engine oil pressure while the engine is running.
- Compare this value to the indicated value. The oil pressure gauge
should indicate approximately the same as the actual pressure, within about
69 kPa (10 psi).
Is the oil pressure gauge reasonably accurate?

| This indicates that the oil pressure gauge is functioning
properly. Check the engine for operating problems, if appropriate.

- Disconnect the connector at the engine oil pressure gauge sensor.
- Place the ignition switch in the RUN position.
- Connect one red lead of a J 33431-B
at engine oil pressure gauge sensor harness connector terminal A
.
- Connect the other lead to chassis ground.
- Adjust the tester to 0 ohms, then to 88 ohms.
Is the oil pressure gauge indication within the specified values?
| 0 kPa
(0 psi) 550 kPa (80 psi)

- Disconnect the connector at the instrument cluster.
- Connect a fused jumper wire between B+ and terminal 27
of the instrument cluster connector.
- Connect a fused jumper wire between terminal 20 of the
instrument cluster connector for CKT 250 (BLK) and ground.
- Connect one red lead of a J 33431-B
at terminal 21 of the instrument cluster connector.
- Connect the other lead to ground.
- Adjust the tester to 0 ohms, then 88 ohms.
