Diagnostic Trouble Code (DTC) 335 indicates the Pressure Feedback EGR (PFE) / Differential Pressure Feedback EGR (DPFE) sensor is out of Self-Test range.

Possible causes are:
• Damaged PFE/DPFE sensor.
• Obstructed pressure inlet hose(s).
• Garage exhaust ventilation system affecting PFE/DPFE sensor operation.
PFE/DPFE system can sense a lack of pressure in the vehicle exhaust system. An efficient garage exhaust ventilation system that is installed during KOEO test mode may generate a DTC 335.
• Remove garage forced ventilation system and properly vent to atmosphere.
• Rerun KOEO test.
