Schematic for the engine speed/timing sensorsTest Step 1. Check for Diagnostic Codes
Connect Cat ET to the service tool connector. Refer to electronic troubleshooting Troubleshooting, "Electronic Service Tools".
Restore the electrical power to the ECM.
Start the engine and run the engine until the engine is at the normal operating temperature.Note: If the engine will not start, monitor the engine rpm on Cat ET while the engine is being cranked. Cat ET may need to be powered from another battery while the engine is being cranked.
Look for these codes on Cat ET:Note: Wait at least 30 seconds in order for any codes to become active.
190-11
342-11Expected Result:One or both of the diagnostic codes that are listed above are logged or active.Note: If the engine will not start and Cat ET displayed 0 rpm during cranking, select "No Engine rpm".Results:
No Engine rpm - Engine rpm is not indicated on Cat ET. Proceed to Test Step 2.
Active or logged code - There is an active diagnostic code or a logged diagnostic code for an engine speed/timing sensor. Proceed to Test Step 4.
No codes - Neither code is active or logged.Repair: Refer to troubleshooting without a diagnostic code Troubleshooting.STOPTest Step 2. Check the Installation of the Sensor Assembly
Remove the electrical power from the ECM.

Left side view (1) Engine (2) Mounting flange (3) Bracket
Visually inspect the sensor assembly without removing the sensor assembly from the engine. Flanges (2) must be flush against engine (1) in order to ensure proper operation.Inspect bracket (3). Verify that the bracket securely holds the flanges of the sensors flush against the engine.Verify that the bracket is not bent. If the bracket is bent or if an obstruction is preventing the sensor assembly from being installed correctly, the engine will not start.Note: The bracket cannot be replaced separately.
Remove the sensor assembly from the engine. Inspect each sensor. Replace the sensor, if necessary.

Exploded view of the engine speed/timing sensors (4) O-ring seals
Ensure that one O-ring (4) is installed on each sensor. Check the O-rings for damage. Replace the O-rings, if necessary.Results:
OK - The sensor assembly's components are OK.Repair: Perform the following procedure in order to properly install the sensor assembly:
Lubricate each O-ring with engine oil.
Fully seat the sensor assembly in the engine.
Tighten the bracket bolt.
Connect the sensor's electrical connectors. Verify that the connectors are latched on both sides.
Ensure that the harness is properly secured, and that the tie-wraps are placed in the correct location. Proceed to Test Step 3.
Not OK - At least one of the sensor assembly's components is not OK.Repair: Obtain a new sensor assembly. Perform the following procedure in order to properly install the sensor assembly:
Lubricate each O-ring with engine oil.
Fully seat the sensor assembly in the engine.
Tighten the bracket bolt.
Connect the sensor's electrical connectors. Verify that the connectors are latched on both sides.
Ensure that the harness is properly secured, and that the tie-wraps are placed in the correct location.Verify that the problem is resolved.STOPTest Step 3. Inspect the Electrical Connectors and the Wiring
