resistance. If the circuit tests normal, replace the ECM. 3. Ignition ON, test for 4.8-5.2 volts between the 5-volt reference circuit terminal 2 and ground. If less than the specified range, test the 5-volt reference circuit for a short to ground or If greater than the specified range, test the 5-volt reference circuit for a short to 4. Verify the scan tool Engine Oil Pressure Sensor parameter is less than 8 kPa (1.2 psi). If greater than the specified range, test the signal circuit terminal 3 for a short to 5. Install a 3A fused jumper wire between the signal circuit terminal 3 and the 5-volt reference circuit terminal 2. Verify the scan tool Engine Oil Pressure Sensor parameter is greater than If less than the specified range, test the signal circuit for a short to ground or an 6. If all circuits test normal, test or replace the EOP sensor. Repair Procedures Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
