hey guys. just got a 96 civic dx with a b16a2 swap on it, using a p2p ecu, 96 civic ex. bought it from a coworker. anyways im trying to pass inspection but i got 2 codes, well 1 now. i fixed the 02 sensor problem. now the only thing left is check engine code p0452 - fuel tank pressure sensor. i've searched and found that cx/dx dont have this sensor at all. but the ex ecu is looking for it. so wat can i do to fix this problem? can i hook up a resistor to the wire from the ecu of the tank sensor? do i hook up a sensor to the tank? i need this code cleared to pass inspection. this is the only thing holding me back. thanks for any info.

nobody got anything....hmm....thought it was honda heaven or something...guess its time to start thinking..

B16_ek

really...no real honda swap experts here????

so i have the same code, i have a cx hatch w/ a dx motor. from what i found out is that there are 3- 91 codes the tank pressure sensor
the low voltage
and high voltage

pm me if you find the answer, i neeed to smog mine to.



thanks

i'll see if I can figure it out... but i thought by coming here i'd get some help.... but..... guess not..

I'm pretty sure there is no way to get around an emissions code. You'll probably have to get a sensor installed.

p2p on a b16a2?
p2p is for a D16Y8.

I was just thinking the same thing...

The EX ECU will look for a tank pressure sensor, which as you mention, your car does not have.

I don't know how everyone gets past it, but with Eran's car ('97 CX with LS ECU) we replaced the entire tank with a '98 EX coupe fuel tank. We were lucky and happened to be parting an EX out, so we took the few things we could use before we got rid of the car.

I think he had heard of some other ways to fix it. I'll try to remember to ask him about it.

just got a jumper wit a p28 and mines fine now

B16_ek

ok first of all, i know the p2p ecu is for soch vtech not for doch vtech...i have a jumper harness with a chipped p28 to make my b16 run a lot better....hello!!!!!!!!

if you do an inspection - emission - and plug the car up with a p28 the inspection machine is gonna say WTF!!! wrong ecu....p28 - OBD1....car is obd2 - hence i need an obd2 ecu to/or in order to pass inspection. but the ecu is freakin reading for a tank sensor...

ya'll know were im getting at... ya'll just trying to go in circles....

since there is a little good tech in this thread ill let it fly. but next time please choose a thread title a little more clearer than the one you picked.

why dont you just get a 99si ecu? or does it also have that sensor?

B16_ek

the title. is asking for help...thats all.. how creative do u have to be for some help???

yes all of ex/si civics have the pressure sensor...

what i want to know from honda-guys/wiring gurus is - can i put a resistor in the wire for the pressure sensor and fool it to be reading as if there was a sensor der?? instead of runnig wires to the tank and installing THE sensor??

Jimster480

I dont see why you wouldnt be able to. Provided that you know the value of the return.

Damn you're being awfully cocky and assholish for a new guy demanding answers.

B16_ek

how is it that i'm being cocky?? or if that matter assholish? im just asking for answers not go in circles... thanks for the info though.. im closer to fixing it now....

85_305

No but your closer to getting fewer and fewer responses

B16_ek

thanks for the help anyway.....guru's....

The people on this board are extremely smart. Perhaps you've pissed them off? Wait around a bit and you will probably get the answer you are looking for.
