Check the fuller nosily they sometimes rot and get little pin holes or the vapor line is rusty, this will cause them to leak vapor and trip your engine light giving you an emissions code, especially in the Dodge caravans VERY COMMON!

How much will it cost to fix codes po551, po442, and po455. I am having these problems in my 2001 dodge durango


two of the codes are EVAP codes. The cost of the repair could be $20 or it could be up to $1200 dollars or more. It just depends on what they find. It could be as simple as a cracked hose or it could be something a little more sever like a NVLD pump or a charcoal canister.

The P0551 is a power steering switch code, i think.

I have trouble starting my 2002 Jeep Liberty plus I have error codes P0442 &P0455. What is wrong? and how can I fix.


PO442 & PO455 are for your evap system which has to do with monitoring your fuel tank and fuel vapor system this shouldn't affect starting at all.

Evap Emissions Leak


This can be because the Gas cap is not holding the pressure. I would start there first.
