If the check emission system light is illuminated on a 2010 Acura TSX, it indicates an issue with the EVAP system. The EVAP canister, also referred to as the purge valve, is situated on the driver side firewall to the left of the brake booster and master cylinder in the car. This canister is filled with activated charcoal and is designed to capture emissions released by your vehicle, making it more environmentally friendly and healthier for occupants. A failed canister may result in a fuel smell or a sulfur-like odor inside the vehicle, which can be harmful to breathe and cause the car to fail an emissions test, leading to potential fines. If you detect such odors or receive a trouble code, it is advisable to bring the car to a professional mechanic for inspection and repair.
