Troubleshooting Test Steps Values Results
1. Inspect Electrical Connectors and Wiring
A. Turn the keyswitch to the OFF position.
B. Inspect the connectors for the speed/timing sensors. Refer to Troubleshooting, "Electrical Connectors - Inspect".
C. Perform a
45 N (10 lb) pull test on each of the wires in the suspect sensor connector and the sensor connections at the ECM.
D. Check the screw for the ECM connector for the correct torque of
5 N m (44 lb in).
E. Check the ground connection on the ECM for abrasions and pinch points.
F. Check the harness for abrasion and pinch points from the suspect sensor to the ECM.
G. Check that the suspect sensor is installed correctly. Check that the suspect sensor is fully seated into the engine.

Loose connection or damaged wire
Result: There is a fault in a connector or the wiring.
Repair any faulty connectors or replace the wiring harness. Ensure that all of the seals are properly in place and ensure that the connectors are correctly coupled.
Use the electronic service tool to clear all logged diagnostic codes and verify that the repair eliminates the fault.
Result: All connectors, pins, and sockets are correctly coupled and/or inserted. The harness is free of corrosion, abrasion, and pinch points.
Proceed to Test Step 2.

2. Check For Active Diagnostic Codes
A. Turn the keyswitch to the OFF position.
B. Connect the electronic service tool to the diagnostic connector.
C. Turn the keyswitch to the ON position. If the engine will start, then run the engine.
D. Use the electronic service tool in order to monitor active diagnostic codes or recently logged diagnostic codes.
E. Turn the keyswitch to the OFF position.

Diagnostic codes
Result: There are no active diagnostic codes for the pressure sensors.
If there are logged diagnostic codes for the pressure sensors, the fault may be intermittent.
Refer to Troubleshooting, "Electrical Connectors - Inspect" in order to identify intermittent faults.
Result: There is an active 261-11 diagnostic code.
Proceed to Test Step 3.
Result: There is an active 190-8 or 342-8 diagnostic code.
Proceed to Test Step 5.

3. Inspect the Sensors
A. Ensure that the speed/timing sensors are correctly seated in the cylinder block and that the retaining bolts are tightened to a torque of
22 N m (16 lb ft). Ensure that the speed/timing sensors are not damaged.
Replace any damaged sensors. Refer to Disassembly and Assembly, "Crankshaft Position Sensor - Remove and Install" or refer to Disassembly and Assembly, "Camshaft Position Sensor - Remove and Install".
B. Turn the keyswitch to the ON position. If the engine will run, then run the engine.
C. Use the electronic service tool to check if the 261-11 diagnostic code is still active.

Diagnostic codes
Result: A 261-11 diagnostic code is no longer active.
Use the electronic service tool to clear all logged diagnostic codes. Return the engine to service.
Result: A 261-11 diagnostic code is still active.
Proceed to Test Step 4.

4. Check the Crankshaft Timing Ring and the Timing Ring on the Camshaft
A. Remove the
