What is CID 887 & How to Solve It?

What is CID 887:

CID 887 refers to a problem with the vehicle’s fuel system, specifically with the fuel pressure sensor. The ECM detects that the sensor is malfunctioning, leading to incorrect fuel pressure readings and potential engine performance issues such as stalling or reduced fuel efficiency.

‍

Why This Happens:

• Faulty fuel pressure sensor.
  
• Shorted or damaged wiring in the sensor circuit.
  
• Loose or corroded sensor connectors.
  
• Low fuel pressure due to malfunctioning fuel pump.
  
• ECM misinterpreting sensor data.
  
  

How to Fix It:

1. Inspect the fuel pressure sensor and wiring for visible damage.
   
2. Test the sensor’s voltage and resistance to ensure proper functionality.
   
3. Check connectors for tightness and cleanliness.
   
4. Replace the faulty fuel pressure sensor if necessary.
   
5. Inspect the fuel system for low pressure or malfunctioning fuel pumps.
   
   

How to Avoid It Before It Happens:

• Regularly inspect the fuel pressure sensor and wiring.
  
• Perform routine fuel system maintenance.
  
• Keep connectors clean and corrosion-free.
  
• Perform diagnostic checks to monitor fuel pressure.
  
• Clue’s fuel management services track fuel pressure systems and detect issues before they affect engine operation.
