Is purge valve solenoid?
In newer model vehicles the purge valve is electrically operated solenoid controlled by the engine computer. When your engine is off the valve is closed. Once your engine is up and running the computer continuously and moderately opens the purge valve.
How does the purge solenoid work in an EVAP system?
The Vent Solenoid is a normally open valve that is commanded closed to seal the EVAP system and stop air flow into the charcoal canister. 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.
Is the purge control solenoid valve genuine Honda?
This is a genuine Honda part, not third party aftermarket. My local dealer wanted twice this price for the same item and wouldn’t have it for over a week. I ordered this and had in less time at half the cost.
Where is the purge solenoid valve on a muffler?
The Evaporative Emission (EVAP) Canister Purge Solenoid Valve is located in the EVAP canister, above the rear of the muffler. The Evaporative Emission (EVAP) Canister Purge Solenoid Valve is located in the EVAP canister, above the rear of the muffler.
How to open EVAP purge solenoids on Honda Odyssey?
Unplug the electrical connector. Then on the valve itself (not the wire!) there should be two pins. If you have a couple of test leads connect one lead to each pin. Connect battery positive on one and ground or negative on the other. You should hear it click. Read DRD’s post above about opening/closing and blowing through it:
What is the purge valve on a Honda EVAP?
One valve vents the vapor into the intake manifold; it is called a purge valve. The other valve allows air into the tank to equalize pressure, or it can direct the vapors into the charcoal canister so they can be burned off later. This valve is called the canister control solenoid or valve.
How are solenoids controlled in Honda EVAP system?
These solenoids are controlled by a module and can generate codes if an open or short is detected, or if a command did not produce the expected result for the EVAP sensor in the tank. To test the entire system, it is necessary to set the positions of the purge and vent valves to entirely seal the system.
How can I test my Honda EVAP system?
To test the entire system, it is necessary to set the positions of the purge and vent valves to entirely seal the system. For Honda cars and trucks, doing this requires a scan tool that can bi-directionally test EVAP solenoids. On some non-factory scan tools, it may take some time to find the correct menu to control the EVAP system.
This is a genuine Honda part, not third party aftermarket. My local dealer wanted twice this price for the same item and wouldn’t have it for over a week. I ordered this and had in less time at half the cost.
Can I drive with a bad purge solenoid?
It’s certainly possible to drive with a broken purge valve, but we don’t recommend it. The longer you drive with a bad valve, the more risk you run of damaging the vehicle’s EVAP system and other parts. There’s also the possibility of wasting fuel and pumping out more emissions than is necessary.
