Anyone had to fix their canister purge control valve?

Hey All!!

Been a while since i've been on here.. my old girl is still going but got my emissions test coming up... Had some codes on my car P0444 being the culprit.. the other codes were P0171 &P0174.

My research tells me its the canister purge control valve. Has anyone else had to replace theirs?

Any help is appreciated...

The other codes could be CCV leak, or failing pre-cat O2 sensors. I just replaced mine at 190K km.

P0444 is the Purge Valve or also called (breather valve), its located in the front part of the engine, right behind the Power steering fluid tank. Its attached to the engine. it has a sensor attached to it and two hoses. Only the dealer has the part, and the cost is $120, it took me about 15 min to replace.
Here are the steps i took.

1. Remove the air filter with the air ducts(will give you more room)
2. Remove the power steering tank(2 screws) and just move it to the side(no need to remove the hose)
3. Remove the Purge Valve, its attached to the engine (similar attachment as the muffler) has a rubber part which attache to the engine.
4. Remove the sensor
5. Remove the bigger(thicker) hose(you have to push in/pres on the safety pin) when locked it sticks out, to unlock you must push in.
6. Remove the smaller(thinner) hose(coming from engine) twist and pull(might take a while)
7. You are done removing.

Installing the new Purge valve is much faster, You may encounter problems installing the smaller(thiner) hose.(i just greesed the tip of the purge valve and it went in with no problems)
