My Ex is throwing a P1451 Canister Vent Purge valve issue. Is the canister for the Ex hidden on the frame above the gas tank? I looked around the frame in the back of the truck but am having no luck finding it so I'm guessing ill have to drop the tank to get to it. I've read that wire chafing for this valve could be the problem.
View 3 RepliesI have a 1999 Ford Explorer with the V-6 SOHC that is stuttering and stalling when I try to accelerate. A very slight acceleration will get the vehicle moving, but anything coming close to normal gas pedal pressure causes immediate stuttering and/or stalling. Check Engine light came on when problem started yesterday.
Where is the EVAP System Canister Vent Solenoid? I bought a code reader after beating my head against the truck all afternoon and got code "P1451 EVAP System Canister Vent Solenoid Circuit Malfunction". My Haynes book says on the left side frame rail... can't find anything along there that looks like it (based on picture from Rock Auto for replacement part) and found some people online talking about it being in the engine compartment on the passenger side...
Just crawled all over the truck and I think I found the charcoal canister, but couldn't trace it back to the vent solenoid... There was something right next to the canister, but again, it looked nothing like the replacement part listed on Rock Auto...
I'm not too knowledgeable about wiring and electrical systems. I'm getting a P1451 code (EVAP Control System Canister Vent Solenoid Circuit Malfunction) on my 99 4.2. I've read that it could be a bad solenoid, bad wiring, or a blown fuse. So far I've;
- checked (and changed) the related fuse
- checked the wiring for damage at the connector
- checked voltage at the connector (12 volts)
- checked the resistance at the solenoid (around 60 ohms)
- actuated the solenoid with a 9V battery (can hear it opening and closing)
I haven't had a chance to check the wiring all the way back up the frame to yet, but I noticed that the ground at the trailer wiring harness has broken off the frame. Would this potentially cause a fault in the upstream wiring? I'm going to slap a new connector on and bolt it back down anyway, but as it's Labour (Labor) Day I'll have to wait for the stores to be open tomorrow.
I recently got a check engine light. I went and got it checked, the person said its the canister purge valve that needs to be replaced. Where it is located and the difficulty replacing it. The part is cheap and I want to replace it this weekend. 2007 elantra
View 2 RepliesI just had my 3rd Canister purge valve installed a month and a half ago, and it's already dead.
I noticed while I was driving that it was constantly pulsing after the engine warmed up, and continued to do so as long as I was driving.** This did not seem normal to me (I can hear it in the cab).
The solenoid is burning up and measures open circuit. No codes are thrown during the time it continues to pulse, but when it burned up again, the 3 codes (P0441 Incorrect Purge Flow, P0440 Solenoid Failure, P0443 Purge Valve Circuit Trouble) are immediately thrown? indicating the solenoid is fried.
The system runs a series of tests during normal operation, so if there was a problem with an actual leak or clog, it should show up as a test failure code, but does not. My inclination is that the problem is a sensor.
So... p1451. Vent solenoid. I pulled the part and put 12v to it. Opens/closes just fine. Checked resistance on part, 55ohms like it should. Pulled vent canister, no apparent leaks or blockages. I traced wires back to cab. Cannot locate anybroken wiring. I looked up the pinpoint test on this dct and all thats left to test out is the pcm itself. Before I buy the obd2 scanner with all modes I wondering if I am missing something.
I did find a broken ground wire in my searching. Frame to body. My thoughts on a bad ground are that that would cause more than one monitor to register one fault code.
My 2001 6cyl 4x4 Xterra is a clogged gas tank vent solenoid, or as it is called now a "Vapor Canister Vent Valve". For the last 2 or 3 years, very infrequently, the vehicle turns completely off while decelerating (sometimes at very fast speeds so I have learned to be calm and put the car in N and turn the key and keep going with the flow so to speak). It also, either during a stop in idle or accelerating very slowly and steadily, makes popping sounds directly under the left back seat--which is where the gas tank is located. It sounds like the tank (or a metal can if you will) is being sucked in until it gives making the popping/banging sound against the car (underneath).
The other issue this problem seems to be linked to is the engine light coming on when the tank pops. I have had that diagnosed too, and it just reads "engine knock sensor". My previous wonderful mechanic, who moved about 30 states away, is no longer available but he did tell me it sounds like a blocked or clogged gas tank vent solenoid. He also said it's not a big problem per se, but at some point I should probably replace it. Sometimes there are 6 months that go by with no popping, stalling, or engine light coming on. So maybe 'bad gasoline' also plays into this issue?? I did an internet search recently and found a replacement part called a vapor canister vent valve. My question is how easy or hard is this thing to replace? Can it simply be 'blown out' with an air hose, or otherwise 'cleaned' instead of replacing it. The only thing scarier for me to fix than home electrical wires would be anything dealing with GAS.
I need the PCM pinout for a 2002 F150 4.6 For the Purge Control Valve Circuit. If possible the wire schematic would be nice also. Getting code PO443 (( hard code )) I have checked battery voltage at valve connector with key on (( 12.2 volts )) valve resistance is at be 35 ohms so I'm thinking I may have a bad wire or a bad PCM .
View 2 RepliesCEL turned on this morning heading to work. Truck drove completely normal with no signs of altered performance.
Stopped by Autozone after work and they checked it with a code reader.
Came back with P0442 - "Purge Valve Solenoid"
Part sold with or without bracket.
Is this a common part to fail? How can I be sure it has truly failed? Is it acceptable to reset CEL and see if it fails again? If so, how do I reset? Where is part located?
Where the EVAP canister purge solenoid is located on a 1999 Ford Windstar with the 3.8 engine?? I replaced the vent valve that is located on the canister itself but cannot locate the purge solenoid valve.
View 2 RepliesEngine light came on a week ago, finally made it in to get the code pulled yesterday : P0441
From reading on this site, thinking its a faulty purge valve.
I have found pics of its location on an 04, but cant seem to find it on my 08 2.7L.
I have a 06 Elantra having a problem with a p0441 code flow fault I changed purge valve and canister purge valve I don't know what else to do what else can I do to get it to go away permanent so I can get car inspected no codes for my car can be on but only 1 i/m

They want to install a new 9C915 which they called in hand writing a Canister purge sensor but I've seen it called a canister purge valve on another thread by FIREME who puts 9C915 as "toward the driver's headlight assembly, near the radiator. You'll need an 8mm socket to remove it"...

Have a 2012 gas powered Escape XLT, 2.5L 4 cylinder.
I need to replace the evap purge valve. Looking at youtube videos and from other posts it seems easy to replace. My problem is where is it located on this Escape?
Is it under the hood or underneath the driver's side? This is just the valve mind you, not the canister in the back.
I am getting an error code of 1201. Is this the ERG valve? How do I change out? Looking for Pictures or diagram?

View 2 RepliesMy 06 accent GLS has become difficult to start only after refueling, which I'm guessing is related to a bad purge control valve from what I've read. Where exactly is the valve located, and is this something that someone with relatively little automotive repair experience could do on their own? I think I've located it on the backside of the engine near the air intake.
View 2 RepliesI have difficulty starting after I fill the tank (usually to about 3/4 fill, not topping off.)
I searched the forums and noticed the evap. system N-80 purge valve may be the culprit. Other VW's have the issue including one thread on a Touareg.
I think I'm the first with this issue on a Phaeton. Sometimes getting loose gas cap faults too and on occasion a CEL. I had a fuel pump replaced last week, but this problem predates the pump failure.
Does this sound like the issue here? Doesn't it throw a code? I'm wondering why they didn't discover it when the diag'ed the bad fuel pump.
