Evaporative emissions control system check

1. The function of the evaporative emissions control system is to draw fuel vapors from the gas tank and fuel system, store them in a charcoal canister and then burn them during normal engine operation.

2. The most common symptom of a fault in the evaporative emissions control system is a strong fuel odor from under the vehicle. If a fuel odor is detected, inspect the charcoal canister. The canister is located under the vehicle on the left side, forward of the fuel tank (see illustration). Check the canister and all hoses for damage and deterioration.
