The code came back as P0455, any ideas what it could be.

 

what year mustang?and what engine and whatnot


well not sure what year ya got but P0455 indicates Major Leak or no flow Detected in EVAP system.

I just had them fix mine not to long ago. It was the EVAP management valve it was stuck. The part costs like 30 bucks and its behind the right front inner fender well.

You have a check fuel cap light on?

 

2000 V6(please dont move this) and no fuel light

 

Will driving with a stuck valve hurt anything

 

the code is the same on eitehr a V6 or V8. Its evap system. I have no clue if it will hurt or not but if u have emissions it may not pass due to it being messed up

 

Anything on the evap system I could check for myself

 

Tac how much did you pay to get it done? My emissions control valve needs replaced (or so my codes are tellimg me) and i think thats actually the same part. How hard is it to get to the gas tank on a mustang? Ive never dont it. Its a 96 Cobra.

 

I paid like 300 bucks total. TOTAL rip but it was at the dealer and i didnt feel like doing it myself. Also i was assuming my warranty would cover and it didnt so since it was already there i said sure go ahead.

 

This might sound stupid but I got a similar code off my GT at Advance Discount Auto(they'll read the code for you). A website I found listed the code as an EVAP problem. I changed the gas cap, unplugged the battery for ten minutes, plugged it back in, and I have not seen that damn light since then. Spend ten dollars before you fork out 300.00 plus.

 

You could find the valve and see if it hold vacuum yourself. or like the above stats try dat
