As posted previously, I have had a problem with vapor rushing out when I remove the gas cap as well as the nozzle after a fill up. Finally, got a code: 450 - Fuel Tank Pressure Sensor. I searched, and to no avail, can not locate the sensor. Will someone kindly direct me to it's location?

 

Maybe

 

UPDATE: As it turned out, the fuel tank pressure sensor is part of the fuel level sensor assembly..... a $220. part. Well, at least the code is gone.
