What is CID 911 & How to Solve It?

What is CID 911:

cid 911 indicates a fault with the throttle position sensor (tps). the ecm detects an inconsistent throttle signal, affecting acceleration and idle stability.

‍

Why This Happens:

• faulty throttle position sensor.
  
• worn or misaligned throttle body.
  
• wiring harness corrosion.
  
• connector oxidation.
  
• calibration error within ecm.
  
  

How to Fix It:

1. inspect and clean the throttle body.
   
2. test the tps voltage range during pedal movement.
   
3. replace the sensor if output fluctuates irregularly.
   
4. recalibrate the ecm throttle settings.
   
5. ensure harness integrity and connector tightness.
   
   

How to Avoid It Before It Happens:

• avoid excessive moisture exposure in sensor areas.
  
• check for calibration accuracy during tune-ups.
  
• maintain regular throttle body cleaning.
  
• clue’s construction fleet management software tracks throttle and performance data to ensure smooth operation.
