On most vehicles, this component is located on top of the engine, or near the rear of the fuel system. It will have an electrical harness and two vacuum lines attached. One of the vacuum lines runs to the fuel injector rail, while the other is attached to the EVAP canister located near the fuel cell.Nov 18, 2016
The Canister purge control valve is most often located in the engine bay on a hose going from the intake to the canister. It can also be located near the fuel tank.
if your going to clean the valve, you should also blow compressed air into the center opening on the carbon canister…… all the dust/dirt will come out of where the purge valve goes on the canister…. you should also clean the big diameter breather hose that hooks on the inside of the frame……. and also blow …
The most common problem with the purge valve is when it sticks or does not close fully. This may cause the “Check Engine” light to come on. In some cars, a stuck-open purge valve can cause difficulty starting right after refueling at a gas station: for the first few seconds the engine may run rough and stumble.
Causal Failure Factors
If the canister, or any of the supply lines, are blocked or have holes, the solenoid cannot function and the purge control valve will remain closed. In addition, the solenoid’s electrical portion can fail, resulting in the valve remaining closed.
While you can still drive your car with a bad purge valve, you will only expose it to further damage not only to the EVAP system, but as well as to the other parts in your vehicle. The more you drive the vehicle with a bad purge valve, the more you will harm other parts. It is necessary to fix the problem eventually.
The cost to replace a purge valve in your car is generally between $110-$170, with the parts being the expensive price of the replacement, coming in at an average of $75-$110, while the labor usually only runs at about $50, meaning this is a quick and straightforward fix that does not take very long.
Two different things, one of which your car doesn’t have. The OG9-3 does not have EGR (which is “exhaust gas recirculation”) but does have an evap purge valve (which purges evaporative emissions from the fuel tank).
The purge valve precisely controls the amount of fuel vapour that is purged from the charcoal canister. In modern cars, the purge valve is an electrically-operated solenoid that is controlled by the engine computer (Engine Control Unit – ECU).
The good news is that having your purge valve fixed won’t break the bank. All in, the cost to repair a broken purge valve will be somewhere between $100 and $200. Most of that cost is in parts, where the average price of a replacement valve can run up to $100.
When a canister purge valve is stuck in the closed position, it will prevent the system from burning the evaporated fuel in the engine. This will cause a low purge flow code and can cause premature failure of the charcoal canister in the evaporative emissions system.
Never wash the inside of the charcoal canister with any type of liquids. Only use 40-50 p.s.i of compressed air to clean the charcoal canister.
If the canister purge valve fails and sticks open, it will create a vacuum leak that can affect the engine idle speed and quality. A vacuum leak can also be created if the purge solenoid, or any of the hoses that may be attached to it break or become damaged.
Engine Problems. If your canister purge valve is stuck open, however, it creates a vacuum leak that can affect your engine adversely. … This will change the car’s air to fuel ratio, and can cause rough idling (car feels rough and bouncy when the engine is running), as well as difficulty starting.
This valve, although it’s a small component, is crucial for your EVAP system to work properly. Without it, your engine is going to have a hard time working and it will run extremely rich. This rich fuel to air mixture can also have an impact in the long run on other components in your car.
The Purge Solenoid is normally closed but is opened by the PCM to allow manifold vacuum in the EVAP system — thus drawing fuel vapours from the EVAP system. … When the PCM commands the Switching Solenoid to open, the fuel vapours in the tank will be transferred to the canister.
The purge valve ticking noise is most likely normal and should not be noticed inside the cab when the windows are up. If it is too loud inside the cab, then have the valve replaced. The purge valve may be leaking vapor by it and into the engine when you are refueling. … Replace the purge valve to correct the problem.
Check Engine Light
A faulty purge valve can cause your car to throw a code. The most common codes are P0441 and P0446. In this case its likely that the purge valve solenoid is not completely closed or stuck open.
Normally the canister purge solenoid lasts the life of the vehicle, but it can wear out from time to time. If the canister purge solenoid starts to go out, the Check Engine light will come on and your car will not pass an emissions test.
The average cost for fuel evaporative canister replacement is between $404 and $427. Labor costs are estimated between $89 and $112 while parts are priced at $315.
But you might be wondering, will my car run bad without a vapor canister? Well, yes, it would. A bad canister can cause poor engine performance affecting the vehicle’s acceleration.
If the canister is clogged, it may be cleaned using low pressure compressed air. To clean the canister, blow low pressure compressed air into the tank pipe while holding the upper canister pipe closed. If any of the activated carbon comes out, replace the canister.
