1997 Honda Passport Q&A

1997 Honda Passport Question: What do the codes, p1393, and p1406 represent? And what do I replace to remedy.

What do codes p1393 and p1406 mean? -
Answer 1
1406 is egr issue. do not replace the valve yet. the code never identifies a bad part, just a failed syste. it may be a clogged intake manifold port. the 1393 is a rough road sensor. once again, do not replace the sensor until it is checked out. let a shop check these for you and give you a bid.
