Q: 2005 Chrysler 300c has a code P0406. I believe EGR needs replacing, Don't know if it will make it 25 miles to dealer.

asked by on

Car runs but sputters in power sometimes. Got a check engine light that comes on and off but mostly on. Checked the code through the ACC-ON ignition switch and it shows P0406 something with the EGR sensor. The dealer is 25 miles out and I don't trust the car that far. Car feels like it will cut out sometimes and also lurches at other times. I'm still driving it but only 5 or 6 miles from home.

My car has 96000 miles.
My car has an automatic transmission.

P0406 involves the EGR system but that may or may not be the only factor causing your rough running condition. Typically, P0406 will set if you have a failed EGR valve, excessive carbon buildup, an open or short in the wiring harness, a poor electrical connection and/or a leak in the vacuum line to the EGR valve. To obtain a diagnostic and repair you need not drive the car anywhere as YourMechanic is a mobile repair service and thus can come right to your location. If you desire an on-site repair, please request a check engine light diagnostic and a certified mechanic from YourMechanic will pinpoint the cause of the fault and estimate the repair for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
