Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 9 - ENGINE -
DIAGNOSIS AND TESTING)
Diagnostic Test
1.
DTC IS ACTIVE
Ignition on, engine not running.
With the scan tool, Clear DTCs in the Engine Control Module (ECM).
Monitor the scan tool for at least two minutes.
Cycle the ignition key off and on several times, leaving the ignition on for at least 10 seconds at a time.
Start the engine.
Allow the engine to reach normal operating temperature.
With the scan tool, select View DTCs.
Is the status Active for this DTC?
Yes
>> Go To 2
No
>> Refer to the *CHECKING FOR AN INTERMITTENT DTC Diagnostic Procedure. (Refer to 9 - ENGINE -
DIAGNOSIS AND TESTING)
2.
(F851) OIL PRESSURE SENSOR 5 VOLT SUPPLY CIRCUIT VOLTAGE
Turn the ignition off.
Disconnect the Oil Pressure Sensor connector.
Turn the ignition on.
Measure the voltage of the (F851) Oil Pressure Sensor 5 Volt Supply
circuit in the Oil Pressure Sensor connector.
Is the voltage above 4.5 volts?
Yes
>> Go to 6
No
>> Go to 3

3.
(F851) OIL PRESSURE SENSOR 5 VOLT SUPPLY CIRCUIT SHORTED TO GROUND
Turn the ignition off.
Disconnect the Engine Control Module (ECM) connector.
Measure the resistance between ground and the (F851) Oil Pressure
Sensor 5 Volt Supply circuit in the Oil Pressure Sensor connector.
Is the resistance above 1000.0 ohms?
Yes
>> Go to 4
No
>> Repair the (F851) Oil Pressure Sensor 5 Volt Supply circuit
for a short to ground.
Perform the ECM Verification Test Ver. 1. (Refer to 9 -
ENGINE - DIAGNOSIS AND TESTING)
4.
(F851) OIL PRESSURE SENSOR 5 VOLT SUPPLY CIRCUIT SHORTED TO (K936) OIL PRESSURE
SENSOR GROUND CIRCUIT
Measure the resistance between the (F851) Oil Pressure Sensor 5 Volt
Supply circuit and the (K936) Oil Pressure Sensor Ground circuit in the
Oil Pressure Sensor connector.
Is the resistance above 1000.0 ohms?
Yes
>> Go to 5
No
>> Repair the (F851) Oil Pressure Sensor 5 Volt Supply circuit
for a short to the (K936) Oil Pressure Sensor Ground cir-
cuit.
Perform the ECM Verification Test Ver. 1. (Refer to 9 -
ENGINE - DIAGNOSIS AND TESTING)

5.
(F851) OIL PRESSURE SENSOR 5 VOLT SUPPLY CIRCUIT OPEN OR HIGH RESISTANCE
Measure the resistance of the (F851) Oil Pressure Sensor 5 Volt Supply
circuit between the Oil Pressure Sensor connector and the Engine Con-
trol Module (ECM) connector.
Is the resistance below 10.0 ohms?
Yes
>> Go to 10
No
>> Repair the (F851) Oil Pressure Sensor 5 Volt Supply circuit
for an open circuit or high resistance.
Perform the ECM Verification Test Ver. 1. (Refer to 9 -
ENGINE - DIAGNOSIS AND TESTING)
6.
(G6) OIL PRESSURE SENSOR SIGNAL CIRCUIT SHORTED TO GROUND
Turn the ignition off.
Disconnect the Engine Control Module (ECM) connector.
Measure the resistance between ground and the (G6) Oil Pressure Sen-
sor Signal circuit in the Oil Pressure Sensor connector.
Is the resistance above 1000.0 ohms?
Yes
>> Go to 7
No
>> Repair the (G6) Oil Pressure Sensor Signal circuit for a
short to ground.
Perform the ECM Verification Test Ver. 1. (Refer to 9 -
ENGINE - DIAGNOSIS AND TESTING)
