correctly installed.Results:
The harness is OK. - Proceed to Test Step 2.
Not OK - Repair: Repair the faulty connectors or the harness and/or replace the faulty connectors or the harness. Ensure that all of the seals are correctly in place and ensure that the connectors are correctly coupled.If the primary speed/timing sensor must be replaced or the sensor must be reinstalled, refer to Disassembly and Assembly, "Crankshaft Position Sensor - Remove and Install". If the secondary speed/timing sensor must be replaced or the sensor must be reinstalled, refer to Disassembly and Assembly, "Position Sensor (Fuel Injection Pump) - Remove and Install".Use the electronic service tool in order to clear all logged diagnostic codes and then verify that the repair has eliminated the fault.STOPTest Step 2. Check for Active Diagnostic Codes and Recently Logged Diagnostic Codes
Turn the keyswitch to the OFF position.
Connect the electronic service tool to the diagnostic connector.
Turn the keyswitch to the ON position. If the engine will start, then run the engine.
Use the electronic service tool in order to monitor active diagnostic codes or recently logged diagnostic codes. Results:
Diagnostic code 0190-08 is active or recently logged. - Proceed to Test Step 6.
Diagnostic code 0342-08 is active or recently logged. - Proceed to Test Step 6.
Diagnostic code 0261-11 is active or recently logged. - Proceed to Test Step 3.
No active diagnostic codes or recently logged diagnostic codes are displayed. - STOPTest Step 3. Inspect the Sensors
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, "Position Sensor (Fuel Injection Pump) - Remove and Install".
Use the electronic service tool to check if the 0261-11 diagnostic code is still active. Results:
A 0261-11 diagnostic code is still active at this time. - Proceed to Test Step 5.
A 0261-11 diagnostic code is not active at this time. - Use the electronic service tool to clear all logged diagnostic codes and verify that the repair eliminates the fault.STOPTest Step 4. Check the Timing of the Fuel Injection Pump
Check the timing of the fuel injection pump. Refer to Systems Operation, Testing and Adjusting, "Fuel Injection Timing - Check". Results:
OK - The timing of the fuel pump is correct. Proceed to Test Step 5.
Not OK - The timing of the fuel pump is incorrect.Repair: Adjust the timing of the fuel pump. Refer to Systems Operation, Testing and Adjusting, "Fuel Injection Timing - Check" for the correct procedure.Use the electronic service tool to clear all logged diagnostic codes and verify that the repair eliminates the fault.STOPTest Step 5. Check the Crankshaft Timing Ring
Remove the primary speed/timing sensor. Refer to Disassembly and Assembly, "Crankshaft Position Sensor - Remove and Install".
Use a flashlight in order to check
