Where is the Charcoal canister on a 99 volvo s80 2.9 located. Trying to find the purge valve on top of it.

purge valve solenoid/ purge vent/ purge canister... NEVER TOP OFF GAS!!! ruins evap system and activated charcoal from purge canister enters lines clogging purge valve solenoid, problem often causes fuel nozzle to "click" multiple times while fueling

Visit the on-line store, know as reliable-store, they have the repair manuals. I'm sure you will get the solution of your problem.

Location should be back by the fuel tank.

first off, the P1447 DTC is triggered when the EVAP control system isn't operating properly or there is a leak between the intake manifold and the pressure sensor. the parts between the pressure sensor and intake manifold are:

1. EVAP canister purge control solenoid valve
2. EVAP canister purge control valve
3. EVAP canister purge volume control valve (Part # 14930-3M201) YOU WILL HAVE TO DOUBLE CHECK ON THE PART NUMBER WITH THE DEALER FOR THE PRICE.

If you've received this P1447 DTC, chances are that the brick of charcoal in the canister has fallen apart over time, and filled the lines with charcoal. this affects parts 2 & 3 from the above list, and of course the EVAP canister (Part # 14950-1s717 $144.22). but when you replace the canister, you have to replace the EVAP canister vent control valve (part # 14935-54u06 about $100), and don't forget the o-ring (part # 16618-40u00 about $1.60) that goes between the canister and the vent control valve.

If you attack this DTC early enough, all you have to replace is the canister and vent control valve with the o-ring, which will add up to under $300 MSRP...a lot better than paying upwards of $1000 for parts and labor. Don't be scared to do it, it's actually quite simple.

The purge valve is usually on top of the charcoal canister or sometimes in a vacuum line that is attached to the canister. I purges the fuel vapor from the canister when the engine is running. the fuel tank is vented via the canister.

Controlling Emissions How Evaporative Emission Control Systems Work

yes you should see a small round canister with an electrical plug and a vacuum line on each side of it like a tee fitting follow the vacuum line to the big black charcoal canister box or go in the reverse from the charcoal canister backwards and you should find it the charcoal canister should be on the inside of the fender and you will find the purge valve LATER MAN!

1--Evap system hoses
2--Purge Valve
3--Check Valve
4--Air pump
5--Canister valve(some people call canister purge valve)

A crack in an evap hose is the most common thing. I would definitely check the two evap canister hoses. These are easy to fine, one being the J hose, which is in a J shape, and connected to your canister and the other end to a valve. Then the Canister Evap hose, which is 18" or so long with a 4" L on the end of it. It connects to a hard plastic or metal hose that can easily be reached by removing the rear passenger side tire on a 98 S70 turbo. Check these 2 first. I found that the cracks in both of these hoses were where the clicks were or close to them(many old style clips causing this). Check these too, again they will both be connected to the canister valve that is right beside the charcoal canister on the passenger rear side.

The canister purge valve is a computer controlled solenoid valve that allows any stored fuel vapors in the charcoal canister to be recycled back into the engine combustion process. The valve is typically located on or near the throttle body. The canister purge valve is controlled by the power train control module (PCM). The canister purge valve is closed each time the power train computer runs the OBD-II (Onboard Diagnostic Generation II) EVAP monitoring self-test.--------------------------------------------------------------------------------

hi,
I had the same problem, which ended up being a faulty charcoal canister. the canister was causing the purge valve to fail because tiny pieces of charcoal were damaging it. if you remove the purge valve and tap it on a white sheet of paper on a table , if you see tiny black specs then the charcoal canister is faulty.
i hope this helps

9 times out of 10, your gas cap isn't on tight enough. Check your hoses to and from the canister for damage, or possible disconnection. Also check your pcv valve and connecting hose. Last, look to the purge solenoid.
