This P0401 occurred as soon as I put in the ecu after having it re-tuned again. Is there any way a tune can affect something like this? Sounds weird to me...... In the meantime the car has been in the shop a few days and they supplied me with a Dodge Avenger rental. So far the warranty is covering all of this unless they detect that the ecu was reprogrammed which may cause me mucho bucks.... Has anyone experienced something like this before?
I believe code P0401 is Insuffecient EGR flow. Did they find a problem with the air pump or the diaphrams, or did they just testing after the new relay and order the ECU?
