im getting a code 91????
i swapped a b18b into a friends 96 ek. He is using an obd2 ecu and he gets a code 91. i know its the fuel tank pressure sensor but where do i look to fix this problem. where is the fuel tank pressure sensor and why would it through this code after a motor swap... please help... thanks

make sure all fuel lines are properly connected...
99% of the time, this is caused by a bad gas-cap or the fact that it's not TIGHTED enough, therefore allowing no vacuum

The 96 ek, if it is a hatch, does not have the PTANK sensor some specific models have them, but most do not that year. I am actually doing some research now with the help of "acuracing" to see what is required to add it to my 96cx. I am just using a JDM ecu at this point, so I dont see that CEL.

that is definetly an option I would consider.
