Go to Step 2

Go to Instrument Cluster System Check

1. With the engine in operation, measure the actual engine oil pressure.
2. Compare the actual engine oil pressure with the specified value.

Is the difference between the actual engine oil pressure and the specified engine oil pressure less than 68.95 kPa (10 psi)?

68.95 kPa (10 psi)

Go to Step 3

Go to Oil Pressure Diagnosis and Testing .

1. Disconnect the Oil Pressure Sender.
2. Place the ignition switch in the RUN position.
3. Connect one red lead of a J 33431-C at the Oil Pressure Sender connector, cavity A.
4. Connect the other lead to ground.
5. Adjust the tester to 88 ohms.

Does the oil pressure gauge indicate pressure less than the specified value?

211.60 kPa (80 psi)

Go to Step 5

Go to Step 4

Replace the Oil Pressure Sender. Refer to Engine Oil Pressure Sensor and/or Switch Replacement in Engine Controls.

1. Remove the I/P Cluster.
2. Connect a J 39200 DMM (continuity) between cavity 15 of the I/P Cluster and ground.

Is continuity present?

Go to Step 7

Go to Step 6

Locate repair the short to ground in CKT 31 (TAN) between the I/P Cluster and the Oil Pressure Sender. Refer to Wiring Repairs in Wiring Systems.
