2005 Ford Mustang Q&A
2005 Ford Mustang Question: fuel tank pressure sensor assembly
I have a 2005 mustang g.t., the service engine light is on, had a tech check and he said the fuel tank pressure sensor assembly shows a problem, also the fuel fill shuts off when filling the tank, are these problems related and what is involved with changing the pressure sensor assembly? - totempole
These are likely related, and I would not go changing the tank pressure sensor, I think you have another issue. The fuel filling issue may be due to a plugged venting system, which will cause the tank pressure readings to be inaccurate. Can you post which codes you pulled from the engine module? - Bret Bodas
The tank filling issue is not a pressure sensor issue. When you fill your car, the key is off, so the sensor is not even 'on line' so to speak. That sensor is only to check for Evaporative System Leaks. The tank filling issue could very well be a defective vent valve or solenoid or a stuck roll over valve or even, in some cases a saturated carbon canister whose carbon pellets have plugged up the vent valve etc. ( common on other cars ) this is often caused by folks who 'top off' their fuel tanks i.e. just keep filling and the nozzle keeps clicking. Most folks don't realize that this does real harm to your emissions system and can cause very expensive problems. - dandd
