Model: 1997 F150 Lariat 4X4 Fault Code: P1455 Posted: 2010-03-18 12:01

I recently diagnosed an OBD2 fault code P1455 on my 1997 Ford F15-0 Lariat 4x4 with a 4.6L engine and approximately 140,000 miles. The vehicle is currently displaying Code P1455, which indicates a substantial leak or blockage in the evaporative emission control system. I'm looking for reliable troubleshooting steps to identify and resolve this issue without unnecessary repairs. Any insights or advice from experienced owners would be greatly appreciated. Thanks, Arnie

Ford P1455 specifically points to a substantial leak or blockage in the evaporative emission control system. Common causes include damaged fuel cap seals, loose hoses, or a failed charcoal canister. Start by inspecting the fuel cap and all connections in the EVAP system.
