OBD P1450

Hi there:
The first thing that I suggest could be replace the gas cap; also check a possible defective EVAP (Evaporative Emission Canister Vent solenoid). HERE the instructions.


DTC P1450 - Unable to Bleed Up Fuel Tank Vacuum
Monitors the fuel vapor vacuum and pressure in the fuel tank. The system failure occurs when the EVAP running loss monitor detects excessive fuel tank vacuum with the engine running (but not at idle).



Keep in mind that, if problem persists you will need a smoke machine to properly diagnose.


Hope this helps.
