What is CID 1113 & How to Solve It?

What is CID 1113:

CID 1113 points to a problem with the vehicle’s exhaust temperature sensor circuit. This can lead to improper emissions control or failure to complete the regeneration cycle of the DPF.

‍

Why This Happens:

• Faulty exhaust temperature sensor.
  
• Carbon buildup blocking the sensor.
  
• Shorted or damaged wiring in the sensor circuit.
  
• Corroded or loose connectors.
  
• ECM misreading sensor data.
  
  

How to Fix It:

1. Inspect the exhaust temperature sensor for damage or soot buildup.
   
2. Clean the sensor if it’s obstructed by carbon.
   
3. Test sensor voltage and resistance.
   
4. Replace the faulty sensor if readings are incorrect.
   
5. Verify proper regeneration and emissions compliance after repair.
   
   

How to Avoid It Before It Happens:

• Clean exhaust components regularly.
  
• Monitor exhaust temperature using diagnostics.
  
• Replace sensors when necessary.
  
• Clue’s fuel management services track exhaust temperatures and monitor DPF regeneration cycles to improve efficiency.
