Is theCanister purge control valve (evap)difficult to access? Or do i need a Mech? got too much else eating up my $$, Thanks . Need to spend less $, Wife in Hospital

 

Easy as pie.

 

Thanks a mill guys

 

So the CEL should go away by its self, or is there a song and dance that i have to perform?, lol

 

Once you correct the issue, it might take a couple of ignition cycles, but it should turn off. You could clear the DTC and that will turn off the CEL as well.

 

You're assuming (perhaps too optimistically) that replacing the part will cure the defect.

Since the retrieved DTC is NOT a definitive diagnosis, it's usually recommended to perform the recommended tests so you get it right the first time (usually).

 

What are the recommended tests?

 

P1450 - Unable to Bleed Up Fuel Tank Vacuum

Description:
This DTC sets when the evaporative emission (EVAP) running loss monitor detects excessive fuel tank vacuum with the engine running, but not at idle.

Possible Causes:

• EVAP purge valve stuck open
• Blockages or kinks in the EVAP canister tube or EVAP canister purge outlet tube between the fuel tank, the EVAP purge valve and the EVAP canister
• Fuel filler cap stuck closed, preventing vacuum relief (if equipped)
• Capless fuel tank filler pipe damaged, preventing vacuum relief (if equipped)
• Contaminated fuel vapor elbow on the EVAP canister
• Restricted EVAP canister
• EVAP canister vent valve stuck partially or fully closed
• Plugged EVAP canister vent valve filter
• VREF circuit open
• Damaged FTP sensor

Diagnostic Aids:
Visually inspect the EVAP canister inlet port, EVAP canister vent valve filter, and EVAP canister vent hose assembly for contamination or debris.

Check EVAP purge valve for vacuum leak.

 

The purge valve sometimes fails in a "stuck open" condition. An easy check is to remove the hose from the valve and see if there is vacuum at the outlet at idle speed. Shouldn't be any in that condition.
