NOTE: If DTC P1405 is in Continuous Memory, diagnose that first starting with �?«HE50�?». Possible causes: -- EGR valve stuck open. -- EGR vacuum regulator (EGR V.R.) solenoid vent plugged or iced. -- EVR circuit shorted to GND. -- EVR circuit shorted to VREF. -- Pinched/iced pressure hoses. -- Improper vacuum hose connection. -- Plugged/pinched EGR V.R. vacuum hose. -- Plugged EGR tube. -- Damaged EGR V.R. solenoid. -- Damaged Differential Pressure Feedback EGR (D.P.F. EGR) sensor. -- Damaged PCM. In the past threads, most P0402 codes have been due to a faulty DPFE sensor. Originally posted by chongo: Did someone call me out.......LOL here you go.
