sup peeps! well swap my 97 civic d16y7 with a d16y8 motor but got a check engine code 91 fuel tank pressure switch. Has anyone came across of this problem and how to fix it thanks in advance.

 

im sure the search button and a service manual knows how to fix it

 

no, you are the only one to get this problem

 

i had this problem in my 97 ek hatch wit a gsr swap! jus try to find a 96 ex ecu i believe those dont look for that code, thats one option. another is to go obd1 and get a chipped p28. or if ur down, u'll have to drop ur gas tank and add that sensor and all the wirin! best bet is run obd1!

also wat ecu u runnin?
