1. Check the actual engine oil pressure while the engine is running.
2. Compare the actual engine oil pressure to the indicated value.

Is the oil pressure indicated by the gauge approximately equal to the actual oil pressure within the specified range?

69 kPa (10 psi)

Go to Step 2

Go to Step 3

Inspect the engine for operating problems.

Is the engine operating properly?

1. Disconnect the connector at the engine oil pressure indicator sender.
2. Place the ignition switch in the RUN position.
3. Connect one red lead of a J 33431-C at terminal A of the engine oil pressure gauge sensor connector for CKT 211 (TAN), CKT 7 or CKT 383 (TAN/WHT) or CKT 331 (TAN/WHT).
4. Connect the other lead to ground.
5. Adjust the tester to 88 ohms.

Is the test oil pressure gauge reading higher than the specified value?

550 kPa (80 psi)

Go to Step 6

Go to Step 4

1. Disconnect the 17 way IP harness connector.
2. Connect a J 39200 between the instrument cluster connector C3 terminal 11 and the engine oil pressure gauge sensor connector terminal A for CKT 211 or CKT 383 (TAN) or CKT 331 (TAN/WHT).

Does the DMM indicate continuity?

Go to Step 5

Go to Step 7

Locate and repair the short to ground in for CKT 211 (TAN), CKT 383 or CKT 7 (TAN/WHT), or CKT 331 (TAN/WHT) between the instrument cluster and the engine oil pressure gauge sensor.
