Large Evaporative Emissions Leak. Check all the EVAP lines. Most likely one is cracked or the gas cap is no good. The gas cap usually sets a medium leak thou.

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.

Evap Emissions Leak


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

My check engine light is on. The code is P0121


I believe all the Mopar OBDC codes are the same. A list of the 2001 codes were posted on a PT Cruiser site here: 2001 Chrysler codes

Your error says the throttle position sensor and MAP sensor disagree with each other

Check engine light comes on


"po455 large leak" means that you are not maintaining positive pressure in your fuel system. Have a mechanic do a "smoke test" on the fuel system. Could be as simple as a loose gas cap...
