Does EVAP affect idle?
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.
When is the p0497 Honda code detected?
The cost of diagnosing the P0497 HONDA code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour. When is the P0497 HONDA code detected? The ECM has detected pressure in the EVAP system during a non-purge condition.
What is the p0498 code for Honda evaporative emission system?
If the return signal is “OFF” when the Powertrain Control Module (PCM) outputs the “ON” signal to the EVAP canister vent shut valve, the PCM detects a malfunction and stores the P0498 code. The Evaporative Emission (EVAP) canister vent shut valve is attached to the EVAP canister to control the venting of the EVAP canister atmosphere.
What is the purge control solenoid valve in a Honda?
P0497 Honda Description. The Purge Control Solenoid Valve (PCSV) is a device used to meter vapor flow to the engine. The Engine Control Module (ECM) controls the PCSV using a duty cycle signal. The ECM sets the OBDII code when the PCSV is out of factory specifications.
What causes a Honda EVAP canister to shut off?

Where does p0497 evaporative emission system low purge flow?
Engine vacuum draws the fuel vapors into the intake manifold where they are burnt alongside conventional fuel. In some systems, if there is not sufficient change in manifold air pressure or exhaust oxygen content, when the purge control solenoid/valve is opened, a P0497 will be stored and a service engine soon lamp may be illuminated.
Where is the p0497 purge control solenoid located?
The P0497 code is related to the EVAP purge valve. The purge control solenoid/valve is usually located in the engine bay. A constant intake vacuum supply hose (from the engine intake manifold) is attached to one opening of the purge control valve with a second line attached to the only other opening.
