Codes P04XX

[ThomS]

With codes P0401 or any of the 04XX codes
If they stay with the car and not fixed and you still drive the car for a long distance, can your hurt the car or damage something else?

P0401 is an EGR low flow code. It is nothing more than a nuissance. Are you available Saturday morning? I have time then and can fix that. I may know why the 1518 code came back as well. I don't think I pulled the plug from the sensor.

Other than that, how did it run?
