Another name for this should be a purge valve solenoid. Try and find a small green cap on a plastic hose (that comes from fuel tank) in engine compartment, ...

Check out this video on the pugre valve location.

Remove the plastic cover off top of engine . purge valve solenoid under it.

Evaporative Emission (EVAP) Canister Purge Solenoid Valve
Top rear of the engine, on the intake manifold, near the fuel injectors. If you don't know what it looks like google part to see a picture .

It could just be a electrical problem !
A DTC P1655 set indicates an improper voltage level has been detected on the EVAP canister purge solenoid circuit , Can you check electric circuits with a volt ohm meter ?
Diagnostic Aids
Check for the following conditions:
?€¢
Poor connection at PCM. Inspect harness connectors for backed out terminals, improper mating, broken locks, improperly formed or damaged terminals, and poor terminal to wire connection.

?€¢
Damaged harness. Inspect the wiring harness for damage. If the harness appears to be OK, disconnect the PCM, turn the ignition ON and observe a voltmeter connected to the EVAP Canister Purge solenoid driver circuit at the PCM harness connector while moving connectors and wiring harnesses related to the EVAP Canister Purge solenoid. A change in voltage will indicate the location of the fault.

Test Description
The numbers below refer to the step numbers on the Diagnostic Table.

1. Normally, ignition feed voltage present on the output driver circuit with the PCM disconnected and the ignition turned ON.


2. Checks for a shorted component or a short to B+ on the output driver circuit. Either condition would result in a measured current of over 1.5 amps. Also checks for a component that is going open while being operated, resulting in a measured current of 0 amps.


3. Checks for a faulty EVAP canister purge solenoid.


4. This vehicle is equipped with a PCM which utilizes an Electrically Erasable Programmable Read Only Memory (EEPROM). When the PCM is being replaced, the new PCM must be programmed. Refer to Powertrain Control Module Replacement/Programming

Sorry you wasted your money on parts you didn't need ! There is a very specific diagnostic flow to testing this DTC - diagnostic trouble code ! An tools needed , scan tool , vacuum gauge ! the vent solenoid has nothing to do with this code .

Here's a link to what it look's like. Dorman Canister Purge Valve 911 625 2005 Toyota Corolla 4 Cylinders 1...

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.--------------------------------------------------------------------------------

? Do you want to know where it is? There is a Canister Vent valve located on the engine. Then there is a purge solenoid, which is located on top the gas tank.

Hope this help (remember comment and rated this post).

The EVAP service port is located in the EVAP purge pipe between the EVAP purge solenoid and the EVAP canister. The service port is identified by a green colored cap.
