Help! - check engine light - " 91 Fuel Tank Pressure Sensor low input "
Need some help, i posted in the integra forum but i get nothing over there..my 99 gsr just recently threw code 91 for Fuel Tank Pressure Sensor low input.
everything seems to be running fine and i get fairly good gas mileage. the light came on yesterday while driving normally. one thing though, i don't get that suction sound whenever i unscrew the gas cap to fill up. could that be a sign of something? also, i've already tried switching gas caps..somebody help meeeee
.
*mods*
i bought the car with these fuel mods already installed:
aem fpr
high flow fuel pump (don't know the brand)
aem fuel filter
everything else is stock besides an intake
