What is MID 163 & How to Solve It?

What is MID 163:

MID 163 refers to a problem with the Exhaust Gas Temperature Sensor Circuit. The ECM detects an invalid or out-of-range signal from the exhaust gas temperature sensor, which can lead to improper regulation of exhaust after-treatment systems.

‍

Why This Happens:

• Faulty exhaust gas temperature sensor.
  
• Shorted or damaged wiring in the sensor circuit.
  
• Loose or corroded sensor connectors.
  
• Blocked exhaust system affecting sensor data.
  
• ECM failure to interpret sensor data correctly.
  
  

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 specification.
   
3. Check wiring and connectors for damage, corrosion, or loose connections.
   
4. Replace the faulty sensor if necessary.
   
5. Inspect the exhaust system for blockages that might affect the sensor.
   
   

How to Avoid It Before It Happens:

• Regularly inspect the exhaust gas temperature sensor and wiring.
  
• Perform routine exhaust system maintenance to prevent blockages.
  
• Keep connectors clean and free from corrosion.
  
• Perform diagnostic checks to monitor sensor performance.
  
• Clue’s Equipment Maintenance services track exhaust systems to ensure proper temperature regulation and prevent malfunctions.
