What is CID 980 & How to Solve It?

What is CID 980:

cid 980 points to a fault in the turbocharger vane position sensor circuit. when this sensor malfunctions, turbo boost control becomes inconsistent, causing lag or overboost.

‍

Why This Happens:

• faulty vane position sensor.
  
• stuck turbocharger vanes due to soot buildup.
  
• damaged or shorted wiring.
  
• poor ecm calibration.
  
• loose connectors.
  
  

How to Fix It:

1. inspect turbo vanes for free movement.
   
2. clean carbon buildup in the turbo housing.
   
3. test vane position sensor voltage range.
   
4. replace faulty sensor if signal is irregular.
   
5. recalibrate ecm turbo control system.
   
   

How to Avoid It Before It Happens:

• perform turbo cleaning during scheduled services.
  
• avoid running engines at low rpm for long periods.
  
• ensure wiring is shielded from heat exposure.
  
• clue’s construction fleet management software monitors turbo vane systems for consistent boost control and performance.
