I had the check engine light come on over the weekend. Stopped into O'Reillys and read the code: P0401 - EGR Flow Insufficient Detected. I had the same code about 2 -3 months ago. I replaced both the EGR valve and the sensor. Is there something else I should be doing? Did I just get a defective valve and/or sensor back in July?
BTW, I have a 2001 4x2 with 145,000 miles.
Thanks in advance,
