P0400 found, please suggest
2000 Max with 156k miles.
Check Engine lights up, code found 1: P0400. Searched our forum, nothing yet found. Which part of EGR should I start with? Motor valve or temp sensor? clogged valve?
anyway, before I start to dig, any suggestion is appreciated.

I would start by checking and cleaning the EGR valve. Also, check the tubing for clogging and/or leaks; this includes the vacuum line to the MAP sensor.
