Oil Pressure Test

NOTICE: Inspect the engine for installation of an aftermarket oil filter. Review oil and filter maintenance history to make sure that the vehicle has not gone beyond the standard Ford recommended oil change intervals. Check the engine oil level and check the oil for contamination. If the oil is contaminated, engine damage can occur. The source of the contamination must be identified and repaired as necessary.

1. Disconnect and remove the Engine Oil Pressure (EOP) switch from the engine.

2. Connect the Oil Pressure Gauge to the oil pressure port.

3. Run the engine until normal operating temperature is reached.

4. With the engine at idle record the gauge reading.

5. Run the engine at 2,000 rpm and record the gauge reading.

6. The oil pressure should be within specifications; refer to the specifications in the appropriate engine system.

7. If the pressure is not within specification, GO to Pinpoint Test A Pinpoint Tests.
