yo yo yo yo !! well i got the problem fixed . . i guess whoever wired the vtec wired it wrong . . its fixed now ! ! thanx to SkIp_Civic_Ek6 who went out of his was and gave me a call to help me out with wiring and a showed me a diagram . . and also thanx 2 every1 else who had suggestions, but the problem that i suspected at 1st turned out to be the problem . . i still have 2 codes . .

DTC - O2 Sensor Heater Circuit Malfunction
&
DTC - IAT Sensor 1 Circuit Malfunction

anyone know anything about those? one thing i want to point out is that im pretty sure that obd2a harnesses are supposed to have a sensor that goes into the intake before the throttle body . . i dont have that . . can that be throwing a code?

also the next project that im going to go 2 u guys for help is a dual point injection conversion to multipoint fuel injection . . maybe u guys can give me pointers on that ?


(BELOW THIS IS THE OLD QUESTION I ASKED U GUYS AND I GOT FIXED ALREADY)
pretty much my car will not go past 5k rpm .. .. if the vtec is not hooked up will it not let me go past 5k rpm? im running a p72 gsr ecu . . i have a check engine light that says vtec malfuncion . . i tested the vtec solenoid and it pops. well my question is do any of you guys know that if the vtec is not wired on a obd2a will the ecu not let u go past 5k rpm? thanx . .

call eugene @ prostreet right there in la mirada.

KamiKazeEG

i guess that would be the easy way . . but im giving you guys a challenge . . lol you cant ask the teacher for the answer . . lol eventually if we cant figuer it out ill ask eugene ..

blackKready

for one thing , your trying to run a b16 with a GSR ecu. GSR's have IAB's , secondary intake runners. thats prolly your problem. its not seeing them , cause B16 has none. convert the car to OBD1 and run a P30.

KamiKazeEG

well . . its got a blox manifold . . i know for a fact, on my blue eg the one you see in my avatar . . i droped a gsr complete swap in it . with the obd1 p72, and i put a supercharger on it. throwing away the stock p72 manifold. and it didnt bother anything. so i doubt that the butterflys are the problem . . anyone ever disconnect theyre butterfly plugs on theyre obd2 gsr with p72 ecu and experience the car to cut off on the rpm?

KamiKazeEG

anyhow . . i ran 2 other ecu's that werent p72's and it still did the same thing . .

blackKready

clean solenoid and test resistance on pressure switch. sounds like limp mode.

KamiKazeEG

ive opened the solenoid and took it apart . the vtec screen was clean . . im kind of doubting the wiring is done correct .. anyone have the instructions on how 2 wite vtec on a obd2a? ive searched and searched . . no luck . . i only find obd1 . .

i had the same problem with my EK w/GSR. there was a wire going to the dizzy was cut, so it might be something some thing with your ignition...

before listening to Mr. skateboarder man...you might wanna have the car running well on the obd2 system like its supposed to.....then mess with an obd1 conversion if you want.
anyways...i had a b16 in a 96 hatch also, running a obd2a p72.wouldnt rev past 5 grand either until i wired the vtec up to the ecu.
if that doesnt work...then try something else, but i think thats ur problem.

SkIp_Civic_Ek6

could be 2 problems there buddy 1 problem is if u dont wire the vtec up then it wont go over 5 thousand thats when the area its supposed to be popping in and the wires arent hooked up then it wont work. now if you wire it up right and if it is still doing it check the fuel system like the fuel line when you guys did the swap. could be because of the crush washers or something jam most likely its the vtec probably not wired right. go on katmans website he knoes best get ur info on the wiring there bro.

KamiKazeEG

yea, i dont wanna convert to obd1 . . i dont see the need for it . . i just want it running normal and keep it obd2. . i was also thinking the vtec wiring was done wrong . . i also did think about the distributor as a problem . . maybe they used the wrong dizzy when they did the swap .. cause i didn't do the swap, so i didn't know . but i tried taping the vtec wires on the vtec component in the engine bay and at the ecu and doing an ohms test and i showed that the wires from the vtec component wasn't getting to the ecu. thats most likely why i got a vtec malfunction DTC (P1259). but then again im not sure which pin is the for the vtec wiring . . i did have a DTC of P1336 which is CKF sensor no signal before but i found out about the bypass trick. i did that, cleared the codes and it never came back. car idles alot better after that was done. but didnt fix my rpm cut out problem .

KamiKazeEG

yo yo yo yo !! well i got the problem fixed . . i guess whoever wired the vtec wired it wrong . . its fixed now ! ! thanx to SkIp_Civic_Ek6 who went out of his was and gave me a call to help me out with wiring and a showed me a diagram . . and also thanx 2 every1 else who had suggestions, but the problem that i suspected at 1st turned out to be the problem . . i still have 2 codes . .

KamiKazeEG

i also have a EVAP code but its pending . . i know its because i drove the car once without the gas cap so obd2 cars have a gas tank pressure sensor and without the cap it senses a leak and DTC for EVAP malfunction is stored .. I'm pretty sure if i drive the car around after the ecu monitors the evap fuel tank s (FTS) it will see that the pressure is fine and erase the code . .

KamiKazeEG

bump . . maybe some of you technical people know anything about those DTC's i stated above?

blackKready

ive seen some people have issues with the purge solenoid after OBD2a B series swaps into civics. causes idle issues though. pull the backup fuse and reset your ecu , see if it comes back. or maybe youve tried that.

KamiKazeEG

yea . . i have a scanner so it can erase the codes by sending a comand to the ecu . .

KamiKazeEG

2 questions here people . .
a 97 civic obd2a has how many o2 sensors? and where are they located . .

and is the IAT sensor the one that goes on the intake before the throttle body?

blackKready

IAT should be white plastic male clip on one of the runners of the intake manny i beleve. held on by 2 screws. round clip. you should have 2 O2 sensors. one in the exhaust manifold , and one in the top of the cat. if you have a JDM ecu it wont look for 2 O2 sensors anyways , even if it is OBD2A.

KamiKazeEG

hmm . . well i have a skunk 2 manifold . . so maybe it doesnt have a place for the plug .. i have to check that . .

blackKready

if your manifold doesnt have a hole for it , research , i cant see why you couldnt wire a D series intake airstream version in there and use that.

KamiKazeEG

hmm . . anyone know anything about this situation?

KamiKazeEG

not that it really matters . . but challenging ourselves makes us better when theres other problems down the road . . car drives fine . . i would just like to get rid of all CEL's . .

blackKready

if you want rid of the CEL's than fix it. wire in an IAT for one. check your O2 sensor wiring and test the O2 sensor itself for resistance.
