2001. Where is purge valve? - L300 Saturn Cars & Trucks

A purge control valve circuit open.

code p 0440 refers to EVAP system--system malfunction==causes --hose connections --intake leak---EVAP canister purge valve
code p 0441 refers to EVAPO system --incorect flow detected ====causes --hose connections ---intake leak---EVAP canister purge valve
code p 0446 refers to EVAP system---vent control--circuit malfunction====causes wiring---EVAP canister purge valve ---ecm
replace the purge valve
as to where it is , the location will be in the workshop manual or have a shop point it out to you.

code p0443 refers to evaporative emission (EVAP) canister purge valve--circuit malfunction===causes --wiring---EVAP canister purge valve---ECM

circuit malfunction is either wiring and connections problems ( water , dirt corrosion) or the canister purge valve needs replacing

code p0440 refers to evaporative emission (EVAP) system--malfunction=== causes --hose connections --intake leak--EVAP canister purge valve
code po441 refers to EVAP --incorrect flow detected==causes the same as for po440
code po446 refers to EVAP system vent control --circuit malfunction===causes --wiring---EVAP can purge valve--ECM
generally I would replace the purge valve as it is common to all codes

Possible causes- Evaporative Emission (EVAP) Purge Solenoid Control harness is open or shorted
- Evaporative Emission (EVAP) Purge Solenoid Control circuit poor electrical connection
- Faulty Evaporative Emission (EVAP) Purge Solenoid Control

heres a pic I found, http://www.tundrasolutions.com/forums/attachments/camry/14562d1159064715-diy-camry-2-2l-2001-vsv-fromback2frontview.jpg hope that helps ,,,, the vsv is the purge valve,,

the purge valve is part of the EVAP system. p0441 is usually set when the ECM can not monitor the purge valve performance. the EVAP system takes the gas fumes out of the tank and purges them into your intake system while you drive the car. if the ECM doesn't see a drop in fuel tank pressure then it sets the code. most common failure is the purge valve malfunctions or loss of power or ground signal to the purge valve.

Purge Control Valve Problem

The "Purge Control Solenoid Valve" is the "Purge Control Valve".

Rough idle is a typical symptom of something amiss with the purge control portion of the evaporative emissions system. It could be the valve itself is not operating correctly, the evap canister (vapor canister) may be leaking, or full of raw gas instead of vapor, or maybe even the purge control valve is getting a faulty signal from the ECU.

The soleniod is checked by applying a voltage to it and checking to see if it closes, or opens (I'm not sure if its un-energized state is normally open, or normally closed). If the valve is bad it is a no-brainer to replace.

The vapor canister can be removed and checked to see if it is full of raw gas (not supposed to be), but checking it for leaks is a bit involved, and probably requires equipmet not normally owned by a home mechanic. Vapor canister failure on cars with a lot of miles is common. Replacement is the fix.

Of course if the ECU is not sending a purge signal to the valve correctly, figuring out why may proove difficult, and possibilities could even include a faulty ECU. I expect this is unlikely though.

It's a $20 part. I first would change pcv valve because it can give same error if it's plugged up. You can always remove it and shake it. It should rattle around real easy. If not, it should be repalced

The EVAP service port is located in the EVAP purge pipe between the EVAP purge solenoid and the EVAP canister. The service port is identified by a green colored cap.

Hope this help (remember rated the post).

po444 is an evap problem, check the purge valve may be bad, also check the vacuum line going to and leave the purge valve if lines are good replace purge valve,hope this is helpful.
