morning all,
It's an 03 deville. Happened to call Detroit on another point, but learned that
according to their records my recalled fuel pressure sensor was replaced on a certain date by my dealer. Only trouble is I wasn't at the dealer since I bought the car. Hmmmph. Anyone know exactly where this sensor lives in my car? If I knew
the part number of the original and new part, I could determine if the car is safe yet. Not looking to screw anyone, just want to live long enough to see my kids grow up. Any input is greatly apprecheated-apresheeated-upreecheaited-ughprieacheeatid-ueighioschiouciecheeaieghttied---wellcomed.
Thank you,

It's actually a "fuel tank pressure sensor".
It monitors the pressure inside the tank to aid in on board diagnostics of the EVAP system.
On an '03 Deville it's under a plate bolted to the floor inside the trunk.
It's way up by the back seat on the right side.
Several 7mm head screws hold the plate down, you won't be able to tell if the sensor has been replaced by looking at it.

EWill3rd,
thank you for the quick response. Finding the part is not a problem now, and I understand I can't tell the difference by looking at it installed.
If I remove the sensor will there be any difference in the two parts.
Thinking maybe best to just replace the part anyway.

Barry, nope there are no visible differences.
I think the part number changed.
If you want to replace it I am sure it will do no harm.
sometimes they go bad anyway. Take it out slowly so the nipple doesn't break off. It's kind of a pain.
Be careful if the fumes get too strong, get out of the trunk and take a breather.
