What can cause P0497?
A faulty EVAP canister vent valve. A compromised connection in the canister vent valve circuit. A faulty pressure sensor. Damaged or disconnected vacuum or fuel vapor hoses.
What does the p0497 code mean on a car?
The P0497 code, or Evaporative Emission System Low Purge Flow, is indicative of a problem somewhere in the EVAP control system. When a vehicle sets the P0497 code, it lets you know that there is a fault in the evaporative control system, the system which helps to regulate the amount of fuel vapor that is released into the environment.
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.
How to test EVAP purge solenoid / valve operation?
If it resets, continue with your diagnosis. Consult the service manual for particular system specifications and test EVAP purge solenoid/valve operation. Use the scanner to activate the purge control solenoid and physically check vacuum flow with the engine running and the purge control solenoid activated.
When does the EVAP purge valve set code p0497?
The EVAP Purge Valve allows vapors from the EVAP System to enter the intake and go through the engine’s combustion process. When the engine control module (PCM) detects the evap system is not purging when it should, it will set code P0497. No comments yet…

How does purge control solenoid valve ( pcsv ) work?
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. Need more information on how to fix the P0497 HONDA code?
