ok i have the biggest hack job Honda i have ever seen and even Honda doesn't know what to tell me. the day i bought the car i had my head up my *** and didn't look over everything very well. i have a D15b motor with a p2j-1 head on it Honda says that they don't even have a p2j in there books. i only have one 02 sensor plug when i have a ob2 computer and the manual says that there is suposto be two there but there is only one. when i run the right computer it troughs p1166 and p0141 i bought the same bosh 02 sensor (universal) that my buddy has in his Honda and it didn't clear up either of the codes, when i try to drive it it starts and idles at like 1500 then if you dive it it idles fine, but when your driving it when you start getting around 4500 with your foot to the floor it cuts out all through the rpm band from there on. but if i put a auto computer in it it runs fine but troughs all kinds of codes for the auto trany not being there.

for posting your phone number to the world.
why cant you start by posting your problem?

boostedcivicsir

quick google says the p2j-1 is a vtec e head. (personally i have never seen that) so im not even sure.

kinda need to start with knowing what engine is in the car, what ecu, what harness you have.

then go to i have an obd2a (im assuming with your signature) car, so i need a 2a ecu, 2a harness (get one from a dx and make it work it will have the 2 o2 harnesses.) and make it work, sounds like you got someones sloppy seconds, or a project someone else couldnt get towork.

if your honda dealer couldn't tell you a pj2 head was a vtec-e then i think you went to the wrong dealership.

and if you have a manual then you should know where your second o2 sensor should be, so why not purchase one?

some contradictions but the head code is mentioned here.
https://honda-tech.com/zero...age=2

either way, standard SOHC VTEC head.
Note: the D15B dual VTEC ECU is the P2J, but it was never released in the US, so the honda dealership will never be able to pull up those numbers unless they have the JDM EPC. (electronic parts catalog)
That is if I remember correctly... that the head code is not used when looking up parts.

which ECU are you using? P2P?

94EG8

Also, which D15B Vtec engine do you have, theres at least 3 different ones
D15B vtec - OBD1 normal vtec, similar to D16Z6
D15B Vtec - OBD1 Vtec-e similar to D15Z1
D15B Vtec - OBD2 3 stage vtec, oddball JDM only engine as far as i know, first stage is vtec-e, then regular 16 valve operation, then normal vtec. this one takes a P2J ecu that very hard to come by.

slappy95633

p2p is the only ecu that will let the car run normally and vtec to work but it still troughs all kinds of codes about a automatic trany the other ecu is p2n

manual trans P2P(EX ECU) will get rid of the auto trans CELs.
P2N(HX ECU) would run the car like crap and throw CELs for the 5-wire O2 and a few other things.

Does your head have two VTEC solenoids like in the top left of this pic (and in my avatar)?



If so, then you should swap the head because you're never going to find a P2J ECU. Or you could run an AEM EMS like I am, but good luck finding a competent tuner (most Honda "tuners" are crap). Another option would be to put ignition power to the red wire going to the VTEC-E solenoid, and then just use a D16Y8 ECU. You didn't say what car you have so I'm assuming it's OBD2?

btw "trough" is spelled "throw".

Frankly all of those options are bad options. Running the wrong ecu is not a good idea. You need to get ahold of a p2j ecu if you ever want it to run properly. Also you will probably have to wire up those vtec solonoids and check the rest of the wiring.

You could try calling steve at hmotorsonline.com and see if he has an ecu.

Otherwise you should just get a different motor if you cant deal with it.

true, but cali insists on USDM OBD2 ECUs in OBD2 cars. So aim for something close to pass emissions with.
As far as the P2J ECU, only if it has two VTEC solenoids. Most likely it's a P08 or something like that.

I have a P08 ECU for sale. 150 shipped.

Its for the JDM D15B

Its still not really gonna help him, from the code numbers the OP's posted i'm assuming its an OBD2 car, and he's in california, even if it was OBD1 i'm pretty sure your not allowed to run a JDM ECU. somehow i get the impression he might have gotten the OBD2 3 stage vtec D15B vtec, if this is the case he's pretty much screwed, theres only one ecu for that, and theres nothing even close to it in north america.

JeffBro is right. I know everything about this motor why u say? Because I just did this obd2 D15B 3 stage vtec in my 1996 civic lx like yesterday i swear. Because of taking people opinions out there who think they know it all but dont telling me i can run a p2p (EX ECU) and it work it WRONG! When i did use it my car was idling weird. It would go from 1,200 to 500 then back to 1,200. If i try to accerlerate the rpms would drop down to zero and bogg out then cut off. You CANT use d16 maps to run a 1.5 liter motor. You HAVE TO HAVE THE P2J computer to run this motor smoothly and properly. You can not HONDA rigg this motor like all the other ones. This motor is very rare and unique. I got the proper ecu and it freakin pulls...the strongest d series motor i've ever felt. Better than the obd1 d15b cuz i got the same power but save way more gas! But im probably going to unwire the vtec E solonoid from the computer cuz im going to boost it soon.

Scott.

i can top that. i went to honda dealership for them to find me a 96-00 hatchback and the salesmen said, and i quote "i didn't even know those exsisted."

sorry about me being useless and not giving some helpful info
but here's a free bump =]
