Refer to Disassembly and Assembly, "Camshaft - Remove" and refer to Disassembly and Assembly, "Camshaft - Install".If necessary, replace the crankshaft timing ring. Refer to Disassembly and Assembly, "Crankshaft Timing Ring - 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.STOP
No faults found - Repeat this procedure from Test Step 3.Test Step 5. Measure the Supply Voltage at the Sensor Connector
Turn the keyswitch to the OFF position.
Disconnect the speed/timing sensor with the active diagnostic code.
Measure the voltage from terminal 1 on the sensor connector to engine ground.Note: The voltage should read 7.5 to 8.5 VDC.Expected Result:The readings agree with the values that are listed above.Results:
OK - The sensor is receiving the correct supply voltage. Proceed to Test Step 7.
Not OK - There is a fault with the 8 VDC supply.Repair: Repair the faulty connectors or the harness. Replace the faulty connectors or the harness. Reconnect all sensor and ECM connectors. Ensure that all of the seals are correctly in place. Ensure that all connectors are correctly coupled.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 6. Disconnect the Power Supply Connections for the Speed/Timing Sensors at the ECM
Turn the keyswitch to the OFF position.
