'01 V6 Accord threw the 401 code along with the TCS light illuminating. 1,000 miles later, same code plus a new one, 1491. TCS light comes on after car is warmed up and 401 code keeps coming back. The 1491 code now stays on all the time.

Any suggestions?

I do most of my own maintenance and any help is appreciated.

Codes that wont go away usually say there is an open or shorted sensor or wireing.

code 1491 is an egr problem insufficient flow in the egr system.. honda has been having a lot of problem with v6s ...i believe they have a bulletin on the subject you might want to call honda and see if they are willing to help you since it is a well known problem ..hope you dont have too many miles on car
