1. Turn the ignition switch to the RUN position.
2. Disconnect the engine oil pressure sensor.
3. Connect the red lead of J 33431-C to the engine oil pressure sensor connector.
4. Connect the other lead of the tester to ground.
5. Set the resistance dial to 0 ohms.
6. Slowly move the resistance dial to 90 ohms.

Did the oil pressure gauge read 0 at first and slowly move until reading the full scale?

0 ohms-90 ohms

Go to Step 2

Go to Step 3

Replace the engine oil pressure sensor.

1. Disconnect the instrument cluster.
2. Use a J 39200 DMM to measure the resistance between the instrument cluster connector, cavity 15 and ground.

Is the resistance greater than the specified value?

5.0 ohms

Go to Step 4

Go to Step 5

Repair the high resistance in CKT 31 (TAN) between the instrument cluster connector and the engine oil pressure sensor connector.
