What is SPN 520245 & How to Solve It?

What is SPN 520245

SPN 520245: Refers to a fault in the diesel particulate filter (DPF) pressure sensor, which measures the pressure difference across the DPF to monitor its condition.

When SPN 520245 is triggered, it indicates an issue with the DPF pressure sensor, which could affect emissions control and engine performance.

‍

Why It Happened

This fault code is typically caused by:

• A malfunctioning or failed DPF pressure sensor.
• Blockages or restrictions in the DPF system affecting sensor readings.
• Wiring issues or poor connections between the sensor and ECM.
• A clogged DPF that is not allowing exhaust gases to flow properly.
  
  

How to Resolve It

To resolve SPN 520245:

1. Inspect the DPF pressure sensor for faults and replace if necessary.
2. Check the DPF system for blockages or contamination.
3. Inspect the wiring and connectors for any damage or corrosion.
4. After repairs, clear the fault code and restart the engine to verify the fix.
   
   

How to Avoid Before It Happens

To prevent SPN 520245:

• Regularly inspect the DPF system and pressure sensor.
• Keep the DPF system clean and clear from blockages.
• Use Clue to monitor DPF pressure data and receive early alerts for sensor or system issues.
