What is CID 145:

CID 145 refers to an issue with the vehicle's exhaust system, specifically related to the exhaust gas temperature sensor. The ECM detects an out-of-range signal from the sensor, which can result in poor fuel economy, increased emissions, or engine misfires.

Why This Happens:

  • Faulty exhaust gas temperature sensor.
  • Shorted or damaged wiring in the sensor circuit.
  • Loose or corroded sensor connectors.
  • Blockages in the exhaust system affecting sensor readings.
  • ECM misinterpretation of sensor data.

How to Fix It:

  1. Inspect the exhaust gas temperature sensor for damage or malfunction.
  2. Test the sensor’s voltage and resistance to ensure it is within specifications.
  3. Check wiring and connectors for damage or corrosion.
  4. Replace the faulty sensor if necessary.
  5. Inspect the exhaust system for any blockages or damage.

How to Avoid It Before It Happens:

  • Regularly inspect the exhaust gas temperature sensor and wiring.
  • Perform routine exhaust system maintenance and cleaning.
  • Keep connectors clean and free from corrosion.
  • Perform diagnostic checks to monitor sensor health.
  • Clue’s equipment maintenance services track exhaust temperature systems and help prevent issues before they affect engine operation.
