What is CID 975 & How to Solve It?

What is CID 975:

cid 975 refers to a fault in the fuel injector driver circuit. this means the ecm cannot properly control injector timing or pulse width, leading to misfires or low power.

‍

Why This Happens:

• faulty fuel injector.
  
• damaged injector driver wiring.
  
• short to ground in injector harness.
  
• corroded connectors at the ecm.
  
• ecm failure.
  
  

How to Fix It:

1. inspect injector harnesses for chafing or burns.
   
2. test voltage and resistance of each injector circuit.
   
3. clean or replace corroded connectors.
   
4. replace faulty injectors or ecm if confirmed defective.
   
5. clear fault codes and retest engine balance.

‍

How to Avoid It Before It Happens:

• conduct periodic injector balance tests.
  
• keep harnesses secured and clean.
  
• avoid moisture exposure near ecm.
  
• clue’s fuel management services monitor injector health to prevent electrical or timing issues.
