Test Step 1. INSPECT ELECTRICAL CONNECTORS AND WIRING
Turn the Engine Control Switch (ECS) to the OFF/RESET position.
Thoroughly inspect the J1/P1 ECM connector and the J2/P2 ECM connector. Thoroughly inspect any connectors that are associated with the circuit.Refer to Troubleshooting, "Electrical Connectors - Inspect" for details.
Perform a 45 N (10 lb) pull test on each of the wires in the ECM connector and the sensor connectors that are associated with the active diagnostic code.
Check the ECM connector (allen head screw) for the proper torque of 6.0 N m (55 lb in).
Check the harness and wiring for abrasions and for pinch points from the sensors back to the ECM.Expected Result:All connectors, pins, and sockets are coupled and/or inserted. The harness and wiring are free of corrosion, of abrasion, and/or of pinch points.Results:
OK - There are no problems with the wiring and/or the connectors. Proceed to Test Step 2.
Not OK - Repair: Repair the connectors or wiring and/or replace the connectors or wiring. Ensure that all the seals are properly in place and ensure that the connectors are coupled.Verify that the repair eliminates the problem.STOPTest Step 2. CHECK FOR ACTIVE DIAGNOSTIC CODES
Connect the electronic service tool to the service tool connector.
Turn the ECS to the COOLDOWN/STOP position.
Verify whether any of the following diagnostic codes are active or logged:
190-02
190-11
342-02
342-11
If the diagnostic code is logged but not active, run the engine until the engine is at normal operating temperature. The problem may only occur when the engine is at the normal operating temperature.
If the engine will not start, monitor the engine speed on the electronic service tool while the engine is being cranked. The electronic service tool may need to be powered from another battery while the engine is being cranked to ensure that the electronic service tool does not reset.Note: Upon initial cranking, the status for engine speed may indicate that the engine speed signal is abnormal. This message will be replaced with an engine speed once the ECM is able to calculate a speed from the signal.Expected Result:The engine speed signal is normal.Results:
OK - The engine speed is normal.Repair: If there are logged diagnostic codes, there may be an intermittent problem. If the problem is intermittent, refer to Troubleshooting, "Electrical Connectors - Inspect".STOP
Not OK - Diagnostic Codes - An active diagnostic code is present. Proceed to Test Step 4.
Not OK - No Engine rpm - Engine rpm is not indicated on the electronic service tool. Proceed to Test Step 3.
Not OK - Engine Speed Erratic - There are no diagnostic codes for the engine speed/timing sensors, but the engine is not running properly.Repair: Proceed to the appropriate topic in Troubleshooting, "Troubleshooting without a Diagnostic Code".STOPTest Step 3. CHECK THE INSTALLATION OF THE SENSORS AND THE BRACKETS
Illustration 3 g00810795
Sensors and mounting brackets (typical example)
The flange of the sensor should be flush against the engine to ensure proper operation.
Inspect the bracket to ensure that the installation allows the flange of the sensor to be flush against the engine.Verify that the bracket is not bent.Note: The bracket cannot be replaced separately.
Ensure that the O-ring has been installed on the sensor, and ensure that the O-ring is free of damage.
If either of the following diagnostic codes is active, there may be a problem with the assembly of the timing gears on the camshaft or crankshaft:
190-11 Engine Speed Sensor mechanical failure
342-11 Secondary Engine Speed Sensor mechanical failureExpected Result:The sensors and the bracket are installed properly.Results:
OK - The sensors and the bracket are installed properly. Proceed to Test Step 4.
Not OK - Repair: Perform the following procedure to properly install the sensors and the bracket:
Loosen the bolt that holds the sensor mounting bracket to the engine.
Seat the sensor and tighten the bolt.If the sensor will not seat, repair the sensor or replace the sensor, as required.Note: Do not remove the sensor from the bracket.
Ensure that the sensor is properly oriented and that the harness is secured in the proper location.
Verify that the repair eliminates the problem.STOPTest Step 4. MEASURE THE SENSOR RESISTANCE THROUGH THE ENGINE HARNESS
Turn the ECS to the OFF/RESET position.
Thoroughly inspect the ECM connector J2/P2. Refer to Troubleshooting, "Electrical Connectors - Inspect" for details.
Perform a 45 N (10 lb) pull test on the following wires in the ECM engine harness connector P2 that are associated with the engi
