What is CID 1108 & How to Solve It?

What is CID 1108:

CID 1108 refers to a problem with the intake air temperature sensor circuit. When this sensor fails, the ECM cannot accurately adjust the air-fuel mixture, leading to poor engine performance and fuel economy.

‍

Why This Happens:

• Faulty intake air temperature sensor.
  
• Shorted or damaged wiring in the sensor circuit.
  
• Loose or corroded sensor connectors.
  
• Debris or carbon buildup obstructing the sensor.
  
• ECM misinterpretation of sensor data.
  
  

How to Fix It:

1. Inspect the intake air temperature sensor for damage.
   
2. Test the sensor’s voltage output and resistance.
   
3. Clean the sensor and its surrounding components.
   
4. Replace the faulty sensor if necessary.
   
5. Reset the ECM and verify proper sensor readings.
   
   

How to Avoid It Before It Happens:

• Clean the intake air system regularly.
  
• Inspect wiring and connectors during routine service.
  
• Monitor sensor output with diagnostics.
  
• Clue’s equipment maintenance services help monitor intake air systems to ensure optimal engine performance and fuel efficiency.
