Order of inspection
P0497 Evaporative Emission System Low Purge Flow Low
The P0497 code means the expected vapor flow is not reaching the engine when the purge opens. It is usually caused by a purge valve that will not open or a clogged hose. It does not affect driving, but you will not pass an emissions test.
