Common Causes
Faulty Exhaust Pressure Sensor.
Blocked or cracked pressure sensor hoses.
EGR valve malfunction or excessive soot accumulation.
Wiring harness issues (short to ground/power). [1, 2, 3, 4]
Fixes and Diagnostics
Inspect Hoses: Check for cracks, splits, or clogging in the hoses leading to the sensor.
Sensor Replacement: Replace the Exhaust Pressure Sensor if it is sending bad data.
Check Wiring: Inspect for electrical issues or corroded connectors.
EGR System Check: Diagnose and clean or replace the EGR valve/filter, which is a known issue for this code on some models.
Software Update: In some cases, a dealer software update for the ECM may be required.
