Usually they are a unit housing the valve and the solenoid as an assembly. If you do have power there wait for the new valve you ordered and install it. For example: The computer wants to avoid dumping gas vapors into a cold engine. Try unplugging this connector and plug it back in hard and straight and maybe you will be lucky and fix your problem. If I could get the code off for 10 minutes I could pass the smog test.
You might be best off in this case to explain where you are at and what you have done to someone with a tech-2 and get it diagnosed before throwing more money at it. If the O-ring on the gas cap is worn, distorted, or missing, that would also be a large leak. I would check for power on that pink wire and if you don't have it come back. I'm looking under solenoid valve and purge valve for my year truck. It should click once, or on some models it may click repeatedly. If it doesn't click when you manually ground it, replace the purge solenoid. I know the purge solenoid is working because before I reconnected all the tubing I plugged the thing back in, cranked up the engine, and put my finger over the end.
Listen or feel for a clicking coming from the purge solenoid. Mike, First off let me say Thank You, I really appreciate your help. That means the entire fuel supply system must be sealed and tested on a regular basis. I'll check the power on the pink wire to the valve as you recommended and let you know. I also tried putting a vice grip on it and spinning it while applying upward pressure, same result. What causes the P0443 code? If the bolt isn't out completely then it tore the timing belt from slippage and being old.
Put the tape over the light. I clear the code, everything is fine for a week or so, and then it will happen again. The easiest way to find out what this light is telling you is to hook your vehicle up to a scan tool. But, it's also possible to have a lean condition or a rough running engine if the purge valve is stuck open. The dark green and white wire is the ground side. The gas vapors are burned by the engine.
If you have battery voltage, then ground the control side manually using a jumper wire and see if the valve clicks. I did check the battery voltage and it was higher, something like 12. If you have battery voltage, then ground the control side manually using a jumper wire and see if the valve clicks. This won't really become an issue until next September when I have to get a California smog certificate to renew the registration. Updated through the 2004 model year. How does a mechanic diagnose the P0443 code? You must find it and repair it.
All trademarks are property of their respective owners. If your are for a different car, select that vehicle series before searching for the diagnostic codes because not all used by one manufacture are used by the other makes. That opens the vacuum line between the canister and the intake manifold. I plugged the hole with my finger and it ran fine. The engine must be run for two and a haLeft Front minutes with the air conditioner on and rear defroster on.
There may be no drivability problems at all. So, a vacuum leak at that point was plausable, but I didn't think likely. As I stated earlier if the positive circuit is ok and the valve is ok then you should probably take it to someone that has the proper equipment and know how. Posted on Aug 16, 2009 www. Without a scan tool that can control outputs you could check the individual circuits without checking the pcm itself. I'm short on time today so I'll explain what that is when I get a chance.
I spin the fastener with my 8mm socket but it does not back out. The system pulls a vacuum on the fuel system and holds it for a period of time. I was on the road, suddenly the car turned off. If you have battery voltage, then ground the control side manually using a jumper wire and see if the valve clicks. Then check for battery voltage on the feed wire with the key on. You didn't say how you found batt voltage at the purge.
