What is MID 142:
MID 142 refers to an issue with the Crankshaft Position Sensor. The ECM has detected a problem with the signal from the crankshaft position sensor, which can affect engine timing, leading to stalling, misfires, or difficulty starting the engine.
Why This Happens:
- Faulty crankshaft position sensor.
- Damaged or shorted wiring in th sensor circuit.
- Loose or corroded sensor connectors.
- ECM failure to interpret the sensor’s data properly.
- Mechanical issues affecting the crankshaft sensor.
How to Fix It:
- Inspect the crankshaft position sensor for damage or malfunction.
- Test the sensor’s voltage and resistance to ensure proper functioning.
- Check wiring and connectors for visible damage or corrosion.
- Replace the faulty crankshaft position sensor if necessary.
- Ensure that the ECM is receiving the correct data from the sensor.
How to Avoid It Before It Happens:
- Regularly inspect the crankshaft position sensor and wiring.
- Keep connectors clean and free from corrosion.
- Perform routine diagnostic checks to monitor sensor performance.
- Verify ECM signal processing for accuracy.
- Clue’s Equipment Maintenance services track crankshaft sensor performance to prevent timing issues before they affect engine operation.
