Customer Concern: Ford P1450 Fuel Tank Vacuum "Most Common Cause" The Check Engine Light (CEL) is on and the Powertrain Control Module (PCM) sets Diagnostic Trouble Code (DTC) P1450.
Fuel Tank Emissions Vapor Canister Purge Valve Solenoid Assembly w/ Hoses & Bracket Fits 2013-2014 Ford Fusion: amzn.to/2EklIHh
Pocket Scan Tool: amzn.to/2JmtJ24
Tests/Procedures:
1. Check the canister vent solenoid and related hoses for any restrictions and repair as needed. Be sure the canister vent solenoid is open at rest as it should be.
2. If the solenoid and hoses are OK, access the charcoal canister. Verify the canister is not restricted. Replace as needed if it is and recheck operation.
3. The purge valve is a normally closed solenoid. Verify it is not stuck open and applying vacuum to the fuel tank.
4. If the purge valve checks out OK and the canister appears free of any restriction, remove the fuel vent hoses as close to the fuel tank as possible. Check the hoses from the tank forward for any restriction. If the hoses are OK and no external restrictions are found, suspect a possible problem with the fuel tank vent valve(s) in the top of the fuel tank.
Tech Tips: Anything that causes a restriction in the venting of the Evaporative Emission (EVAP) system can cause a code P1450.
