THANKS IN ADVANCE

 

List of code numbers is not valid. Per prior post this quote "P11500, U01000, B0200, P0002,P0202,P1200, P000, AND FINALLY P0400...." The only one that is listed in OE manual is the P0400 which is for the EGR flow malfunction. Try getting codes pulled again at perhaps an Autozone that will do OBDII scans for nothing. Do you have the 2.5 engine or 2.3 miller cycle?

 

sometime there are one 1 or 2 code that is the main problem but they lead to many other code like the problem you have now. buy scan tool from autozone or advance auto part to erase all code and drive it for couple day to see which code came up and verify and fix that code.
