DTC Code P0402
I've read a lot of posts on problems with P0401 Insufficient flow in the EGR and replacing the backpressor sensor to correct, but mine reads "excessive flow detected". Same fix or something different?

Re: DTC Code P0402
Check for a broken vacuum line in loom on back-side of intake plenum between manifold port and EGR solenoid. If broken line is found repair with a piece of 5/32 vacuum hose.
