Acura TL fuel cap light issue persists after replacing EVAP canister purge valve on Acura TL

Some Acura TL owners report experiencing persistent fuel cap light issues even after replacing the EVAP canister purge valve. These problems may require further diagnosis to identify the root cause if the initial replacement does not resolve the warning. Additionally, some owners find that ensuring the gas cap is tightened properly can help, as a loose or improperly sealed gas cap can trigger the warning light. Others have reported needing to inspect other components of the EVAP system, such as the charcoal canister and vent control valve, for faults or leaks that may be contributing to the issue. In some cases, replacing the gas cap itself has been necessary, as a faulty cap can also cause the fuel cap light to activate. If these measures do not resolve the problem, many owners recommend seeking professional assistance from a mechanic or dealership experienced with Acura vehicles for effective diagnosis and resolution.
