Fuel Tank Leak Test: Description

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2003 GMC Sonoma, 2003 GMC Safari, 2003 GMC Jimmy, 2003 Chevrolet S10 Pickup, and 2003 Chevrolet Blazer. However, it is still accessible from the selected car via links, so may be relevant.

Fuel tank leak test is used to locate any fuel or fuel vapor escaping fuel tank area.

Malfunction Indicator Light (MIL) will illuminate after EVAP diagnostics complete 2 test cycles.
