well after the problems with the tranny then repinning it, im all set untill yesterday when i got another CEL light.

well i got to checking them with an Xcal2 and got these.

P0402-EGR Flow ecessive at idle
P1000-Mass Air Flow sensor intermittent
P1406-Differential pressure feedback electric sensor circut downstream hose

can anyone clear this up and dummy it down for me on what may be going on?

car SEEMS to run fine.....no bucking no, maybe a little rough idle nothing major.

thanks alot guys

For the codes P0402 & P1406 I would check the hoses that go from the DPFE sensor to the EGR tube that hooks to the exhaust. Then I would clear the codes and drive the car and see what happens after that.

thanks alot...


and the DPFE sensor would be??

Connected to the hose or hoses that go to the EGR tube that goes to the exhaust.

Or in that general area. I believe it is a black plastic sensor with 2 ports on the bottom and a wire connector.
