What is CID 1116 & How to Solve It?

What is CID 1116:

CID 1116 refers to a problem with the vehicle’s air-fuel ratio sensor circuit. Inaccurate readings can cause improper air-fuel mixture adjustments, resulting in poor engine performance or fuel efficiency.

‍

Why This Happens:

• Faulty air-fuel ratio sensor.
  
• Shorted or damaged wiring.
  
• Dirty or blocked sensor tip.
  
• Loose or corroded connectors.
  
• ECM failure to process data.
  
  

How to Fix It:

1. Inspect the air-fuel ratio sensor for damage or contamination.
   
2. Test the sensor’s voltage output and resistance.
   
3. Clean or replace corroded connectors.
   
4. Replace the faulty sensor if necessary.
   
5. Verify proper fuel-air balance post-repair.
   
   

How to Avoid It Before It Happens:

• Clean exhaust and intake systems regularly.
  
• Inspect wiring and connectors during maintenance.
  
• Monitor air-fuel ratio data with diagnostics.
  
• Clue’s fuel management services ensure air-fuel systems are calibrated for optimal performance and efficiency.
