What is CID 907 & How to Solve It?

What is CID 907:

cid 907 indicates an issue with the turbocharger boost pressure sensor circuit. the ecm detects that the boost sensor signal is outside its expected range, leading to reduced power and poor engine response.

‍

Why This Happens:

• faulty turbo boost pressure sensor.
  
• damaged or shorted wiring in the boost circuit.
  
• loose or corroded connectors.
  
• blocked turbocharger or intercooler system.
  
• ecm failure to process pressure data correctly.
  
  

How to Fix It:

1. inspect the turbo boost pressure sensor and its wiring.
   
2. test the sensor’s voltage and compare it with specifications.
   
3. clean the intercooler and turbo lines for obstructions.
   
4. replace faulty sensors or connectors if necessary.
   
5. clear codes and verify boost pressure readings.
   
   

How to Avoid It Before It Happens:

• regularly inspect the turbo system and sensors.
  
• keep air and boost lines clear of debris.
  
• perform ecm diagnostic scans during service intervals.
  
• clue’s construction fleet management software monitors turbo performance and ensures engines stay efficient under load.
