What is CID 82 & How to Solve It?

What is CID 82:

CID 82 refers to a problem with the exhaust gas temperature (EGT) sensor. The ECM detects that the sensor’s signal is out of range, which can affect exhaust temperature regulation, leading to increased emissions or poor engine performance.

‍

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.
   
2. Test the sensor’s voltage and resistance to ensure it is within range.
   
3. Check wiring and connectors for visible 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.
