What is CID 1004 & How to Solve It?

What is CID 1004:

cid 1004 indicates a problem with the crankshaft position sensor circuit. this sensor plays a crucial role in timing engine combustion and ensuring smooth engine operation.

‍

Why This Happens:

• faulty crankshaft position sensor.
  
• shorted or damaged wiring.
  
• corroded connectors.
  
• timing belt or chain misalignment.
  
• faulty ecm processing.
  
  

How to Fix It:

1. inspect the crankshaft position sensor for damage.
   
2. test the sensor’s voltage and signal output.
   
3. check wiring and connectors for visible damage.
   
4. replace the sensor if the voltage remains irregular.
   
5. verify proper timing after sensor replacement.
   
   

How to Avoid It Before It Happens:

• inspect timing belts and chains regularly.
  
• maintain clean and intact wiring.
  
• perform diagnostic checks to monitor crankshaft position.
  
• clue’s equipment maintenance services track engine timing and help avoid sensor issues that affect combustion.
