P1450 Code 98 Windstar

[w9nl]

Service Engine Soon light came on the other day. Everything is running fine right now. I went to Autozone and the pulled a P1450 code. The scan tool they used said it was a Auxiliary Emission Control.

The Ford site says it is a Unable to Bleed Up Fuel Tank Vacuum.

Any thought's on what I might try here? I have a service appt next Wednesday with Ford so I have a few days to see if I can save a few bucks here.

The only thing I have done recently was I replaced the existing AM/FM radio with a after market AM/FM/CD player. The light came on the next day.

Could I have pinched a hose behind the area where the radio goes? Thats the only thing I can think that I may have done.

Here's the list of possible causes for a 2000, hopefully some of these will steer you in the right direction for your 98 (looks like the gas cap or EVAP lines would be a good easy place to start looking):

-Blockages or kinks in EVAP canister tube or EVAP canister purge outlet tube (between fuel tank, EVAP canister purge valve and EVAP canister)
-Fuel filler cap stuck closed
-Contaminated fuel vapor elbow on EVAP canister
-Restricted EVAP canister
-CV solenoid stuck open
-Plugged CV solenoid filter
-EVAP canister purge valve stuck open
-VREF circuit open
-Damaged FTP sensor

Thanks for the reply. I'm still looking for an answer if the tube runs through the area where the radio is. If it does, I suppose I could have kinked in when I installed the radio.

How do you know if the Fuel filler cap is stuck closed??

You have to hook up a pressure gauge to the cap to see if it bleeds pressure, for the 2000 it relieves pressure above 14kPa. But for most people, it's cheaper just to try a new gas cap. Check all the EVAP tubing first, everything should be in the engine compartment and near the canister by the fuel tank.

I replaced the gas cap yesterday. The tank was almost empty and when I opened the cap I got alot of air hissing. When I mentioned this to the auto parts guy, he thought that could be the problem. So, new cap, drove a bit, fresh tank of gas...and still have the light.

I am not going to comment on whether or not the cap is the problem but once a fault is corrected it will take 2 or 3 OBD11 drive cylcles to automatically clear the CEL light and about 40 drive cylces to purge the code from memory.

Just Wondering if you were able to fix this problem, I have one I'm checking this week, I know the gas cap is fine.

After taking it to the Ford dealer I really think I fixed it by replacing the gas cap. They read the same code, cleared it and then looked for a problem but didn't find anything. Go figure...

At least the CEL has stayed off, even after a 2k trip.
