Conditions Generating This Code

The Electronic Control Module (ECM) generates this code under the following conditions:

1. The ECM detects an intermittent or complete loss of signal from the primary speed/timing sensor for 2 seconds.
2. The engine has been running for more than three seconds.

System Response

• If equipped, the diagnostic lamp will flash, and the derate lamp will illuminate. The shutdown lamp may also come on.
• The diagnostic code will be logged.
• The ECM will switch to using the signal from the secondary speed/timing sensor.

Possible Performance Effect

• The engine will be derated.
• If the signal from the secondary speed/timing sensor is also lost, the engine will shut down.

Troubleshooting

This diagnostic code indicates a loss of signal from the primary speed/timing sensor. To address this issue, perform the following diagnostic procedure:

Engine Speed/Timing Sensor Circuit Test

Follow these steps to test the engine speed/timing sensor circuit:

1. Check the connections to the primary speed/timing sensor for any signs of damage or corrosion.
2. Verify that the wiring to the sensor is intact and properly connected.
3. Use a multimeter to check the sensor’s voltage and signal output.
4. If any issues are found with the sensor or its wiring, repair or replace the components as necessary.

Results

• OK: If the sensor and its circuit are functioning correctly, the test is complete.
• Not OK: If there are issues with the sensor or its circuit, take corrective action based on the test results.
