egr problem,help.....

[bedrck46]

have you changed the DPFE sensor and if you did are you certain the hoses are connected correctly??

After I had 0402, I changed egr, solenoid ($65), and sensor (~$70) only to find out that I had a bad coil in #3. Once that and the corresponding plug was replaced it went away. Though that sensor does seem to be the usual culprit.

Possible causes:

EGR valve stuck open.
EGR vacuum regulator solenoid vent plugged or iced.
EVR circuit shorted to GND.
EVR circuit shorted to VREF.
Improper vacuum hose connection.
Plugged/pinched EGR Vacuum Regulator Solenoid vacuum hose.
Plugged EGR tube.
Damaged EGR Vacuum Regulator Solenoid solenoid.
Pinched/iced pressure hoses.
Damaged Differential Pressure Feedback EGR (D.P.F. EGR) sensor.
Damaged PCM.

Possible causes:
Improper upstream pressure hose connection.
Upstream pressure hose plugged.
Plugged or damaged pressure pickup tubes
