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.

 

its a 96 dx hatchback. Should i just tell my friend to use jumper and use a stock obd1 ecu instead of the us obd2 ecu?

 

yes, i'd use the obd1 ecu

 

coo, rite on. problem solved... I love HT....
