What is CID 1062 & How to Solve It?

What is CID 1062:

CID 1062 refers to a problem with the fuel pump actuator circuit. The ECM detects improper signal voltage or movement from the actuator, which regulates fuel flow to the injectors.

‍

Why This Happens:

• Faulty fuel pump actuator.
  
• Damaged wiring harness or poor connections.
  
• Malfunctioning fuel pressure regulator.
  
• ECM misinterpretation of actuator feedback.
  
• Fuel contamination or blockage.
  
  

How to Fix It:

1. Inspect the fuel pump actuator and wiring for damage.
   
2. Test actuator voltage and resistance.
   
3. Replace the actuator if it fails diagnostic tests.
   
4. Clean the fuel system and replace clogged filters.
   
5. Reset ECM codes and retest fuel delivery pressure.
   
   

How to Avoid It Before It Happens:

• Maintain fuel cleanliness through timely filter replacement.
  
• Inspect electrical connectors routinely.
  
• Perform regular system diagnostics on the fuel pump actuator.‍
• Clue’s fuel management services monitor actuator operation to prevent engine shutdowns.
