Does anyone know how to get rid of this code??

 

try disconnecting the battery.. need more info on the swap and circumstances.. that codes is only for a 96+ obd2 cars i think...

 

its a d16y7 block, d16y8 head, d16y7 wiring harness

 

do you have your purge system hooked up and is your gas cap on?

 

what car is this motor in and what ecu do you have?

 

1997 dx
1997 ex ecu
minime

is the dx purge different than the ex?

 

I am not sure if the purge are diff. but that code is for a 99+ car though. Are you sure you do not have a 99-00 ecu. b/c the 96-98 cars do not have that sensor.

 

yes 96-98 ex's have a 91 code

 

well youre getting it because youre ecu isnt seeing pressure in the fuel tank so either you have a leak somewhere stopping the pressure from building up, or youre fuel tank pressure sensor is bod/nothooked up/ (insert any other sensor trouble here).

 

dx fuel tanks dont have this sensor, this is a problem many people run into even when they swap dohc motors

 

I have had this damn code ever since I did an auto to manual on my 96 ex. The helms has extensive troubleshooting to find out the problem, but you will need a multimeter and a vacuum pump to get started. I check all the lines, and tried replacing the canister so far, no luck. What year engine/head/harness are you using? Ive been wondering if the problem is a wiring issue that needs to be sorted out.
