P0452B Fuel Tank Pressure Sensor Low Voltage Ok, to give a long story short.
2002 Trans Am
46k on the clock
Fuel system never touched
Has Cam, Exhaust, Lid, Catted Y.
Has been Dyno tune by Eastside Perf. in Wallingford CT but no longer in the LSx biz.
AIR pump removed 1-1/2 years ago, they tuned out the code for that.
This came on a month ago, checked and cleared last night, came back on the 2nd start up.
Searched here and Google but for my car since nothing was ever really messed with, why did this kick, how do I fix, and since I have scanable emissions, can we tune this code out???
In the internet, these post come up but no one ever really post answers so I never know how it gets resolved.
http://www.obd-codes.com/p0453 the closest active link I found. I did notice some fuel smell. Sounds like the sensor crapped out but I think that kinda stinks that I gotta pull the tank.
