What is CID 1034 & How to Solve It?

What is CID 1034:

cid 1034 refers to a fault in the exhaust after-treatment pressure sensor circuit. this can lead to improper dpf (diesel particulate filter) regeneration, which can affect vehicle emissions and performance.

‍

Why This Happens:

• faulty exhaust after-treatment pressure sensor.
  
• shorted or damaged wiring in the sensor circuit.
  
• blocked or restricted exhaust system.
  
• corroded or loose connectors.
  
• ecm failure to interpret the sensor’s readings.
  
  

How to Fix It:

1. inspect the exhaust after-treatment pressure sensor and wiring.
   
2. test the sensor voltage and resistance.
   
3. check exhaust system for restrictions or leaks.
   
4. replace the sensor if malfunctioning.
   
5. verify dpf regeneration and sensor response after repair.
   
   

How to Avoid It Before It Happens:

• clean exhaust systems and dpf regularly.
  
• perform routine diagnostics on exhaust pressure sensors.
  
• inspect wiring for wear or damage.
  
• clue’s fleet management software tracks exhaust and dpf systems to ensure proper regeneration.
