i put a gsr swap in a 97 integra ls. everything is obd2a. the only code i get is 453 with is a evap code but the reason the code keeps coming on is the ls dont have have a fuel tank pressure sensor. i tried tricking the ecu. but other codes would come on. like 1457 and 420. those code only come on with i trick the ecu. when i leave it alone. just the code 453 and 450 come on. does anyone knoe how to hard wire a ftp sensor into the tank or fuel line. i cant seem to find a obd2a gsr gas tank and the obd1 convertion cost too much and wont pass emission. think about getting a jdm ecu but that will be the same thing. does anyone know if a 96 se integra have one of them ftp in the tank.

 

Supposedly theres a way to trick the ecu. Because i am having the same problem with my car. I just recently swapped a gsr motor into my integra rs. And yes of course i got the same code. ALso i didn't pass emission. But from the research i gathered. http://technet.ff-squad.com/code91.htm. Thats the best information i could find. I haven't tried it myself yet. But I picked up a potentiometer and i just haven't gotten the time to try that out. Good luck with that if this helps in any way
