Acura P0498 Code

If your Acura is displaying the P0498 code, it could be a sign of a faulty evaporative emission (EVAP) canister vent shut valve control circuit. This code is triggered when the powertrain control module (PCM) outputs the ON signal to the EVAP canister vent shut valve, and the return signal is OFF for 5 seconds or more. Poor connections or loose terminals at the EVAP canister vent shut valve and the PCM, an open or short in the wire between the two, an open in the wire between the EVAP canister vent shut valve and the under-hood fuse/relay box (PGM-FI sub-relay), or a faulty EVAP canister vent shut valve are all potential causes of this issue. Fortunately, there are solutions available to you so you can get your Acura back on the road.
