What is CID 982 & How to Solve It?

What is CID 982:

cid 982 refers to an issue with the engine coolant level sensor circuit. the ecm detects that the sensor signal is out of range or missing, which can lead to overheating or inaccurate coolant warnings.

‍

Why This Happens:

• faulty coolant level sensor.
  
• damaged or shorted wiring harness.
  
• corroded connectors.
  
• low coolant levels.
  
• ecm misreading sensor data.
  
  

How to Fix It:

1. check coolant level and top up if low.
   
2. inspect the coolant level sensor for damage.
   
3. test voltage and resistance across sensor terminals.
   
4. clean or replace corroded connectors.
   
5. replace the sensor if readings remain incorrect.
   
   

How to Avoid It Before It Happens:

• maintain correct coolant levels.
  
• clean connectors during every service.
  
• perform periodic system checks.
  
• clue’s equipment maintenance services help monitor cooling systems and prevent overheating before damage occurs.
