It's a $10-$15 switch threaded into a power steering pressure hose just below the power steering fluid reservoir on the driver's side of the engine near the front. Look at the reservoir cap, slightly to the right (facing the front of the engine), and down a few inches. Unplug the 2 wire connector, then hold the boss the switch is screwed into with one wrench and turn the switch with another wrench. When it comes loose, plug the opening with a finger so you don't drain all the fluid and quickly screw in the new switch. 5 minute fix, then have someone clear your trouble codes.

Check to see if you have excess air pressure inside the reservior. I removed my cap and had alot of air blast out the top which made me wonder how air was entering the system. Found fluid had leaked through the sensor and into the connector. If fluid can go out then we know air can enter so had to replace the sensor and went ahead and changed the fluid while I was at it. Disconnected the neg battery terminal to reset the codes and everything is running great!.

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.

Already had power steering fluid flushed. P0551

you need the power steering performance switch. around $30 at autozone. I am not 100% sure of the name. Basically what it does is raise the idle when turning at slow speeds to keep the engine from dying on you.
