Evap Canister Vent Valve Circuit High at Justin Wells blog

Evap Canister Vent Valve Circuit High. An illuminated check engine light. The p0499 code stands for “evaporative emission (evap) system vent valve control circuit high,” which means the powertrain control module (pcm) detects a problem with the evap system’s vent valve. The most likely cause of an abnormal pressure in the evaporative emissions system vent valve control circuit is an improperly installed fuel. The evap vent valve can produce different symptoms for each vehicle, but two common symptoms are a check engine light and a noticeable fuel smell. P0499 code indicates high voltage in the evaporative emission system vent valve control circuit. A broken charcoal canister, a. Common causes for this error code to appear are: Detailed information on diagnosing and repairing a p0499 dtc code which refers to a high resistance in the evap vent valve solenoid circuit. The fault code p0499 can be caused by a faulty evaporative emission vent solenoid valve, an open or shorted harness for the solenoid valve, a poor electrical circuit connection for the solenoid valve, or a faulty engine control module (ecm). Test the vent valve for open circuits or shorts to diagnose the problem accurately. Check the gas cap, purge solenoid, evap canister, hoses, pressure sensor, and fuses for issues. Check for acid damage to wiring under the. Some of the common causes of the p0499 code include evap vent valve failure, wiring issues, and pcm failure. A faulty purge control solenoid or valve, a faulty evap canister vent valve, a clogged charcoal canister or. Nvld canister vent valve solenoid circuit high;
