[ **** FIXED ****]


Ok... i bought this 96 hatch about a month ago, with a B18C1

Just recently i started to test out VTEC... but when i get up to the approprate RPMs, NOTHING. I first started out by changing the oil (Mobil 1) and it hasnt fixed my problem.

So here are a few pictures of the engine bay. See if you can notice anything wrong. I appreciate the help.



Boring ol motor



Appears everything is plugged in



On the right something is not plugged in and just above it that nozzle sucks in air



Seems like this should be plugged in somewhere

The orangeish/clear hose connects to the bottom of the fuel filter. The thing above it looks like an IAT sensor to be plugged into the intake tube.

It sounds like you have no idea what you're doing... Better get a manual or someone to help you...

 

If i had an idea as to what i was doing... I wouldnt ask any questions.

 

IAT... plug that **** in man. Your car will run so much better.

 

Definitely a sensor missing.

If im not mistaken the IAT plugs in to there... but theres already something there... does this sensor go to the short ram? And would this even be the cause for VTEC to not kick in?

 

up

 

Plugged in... now im letting the ECU reset

 

read the ECU thread at the top of this page and learn how to pull the code and pull what codes the ECU is saying. then report back with those findings

 

the IAT(intake air temperature) sensor has absolutely nothing to do with your vtec working or not, and it won't run noticably better when its plugged into the intake path. may run a tad rich with it laying out, no big deal.

what you need is a guy like me to come over there and go through your wiring, but im only local to michigan about a week or two out of the year

have you checked for codes?

jump the blue connector near your ecu and see what basic codes your CEL flashes. long pulses = 10, short pulses = 1. extra long pulses = seperation between numbers. directions are here in the forums. an example would be long pulse long pulse short pulse = 21. 21 is either vtec pressure switch of vtec solenoid, i forgot. etc.

then say you get a code for vtec pressure switch... you find which location the vtec pressure wire goes to at the ecu (d6 or something?) and check for continuity and make sure things are running to the correct location.

etc etc etc.

happy wiring

edit: you may also want to clean out the vtec solenoid too, theres directions for that in the archives.

 

after looking at it again i think i see where some wiring went wrong.

you have two IAT sensors running right now.

the sensor thats just laying out is probably the correct plug for IAT on the original d series motor, those are your actual iat wires most likely. call this IAT #1.

the one that is plugged in to the intake manifold is also an iat sensor, just the different design, but that plug going to it is most likely a vtec pressure switch plug or an engine coolant temp plug. call thi IAT #2.

you will most likely need to cut the plug off of the IAT #1 and #2.

leave the plug and sensor #2 in their location.

take the wires from iat #1 and wire them up at #2.

take the wires from #2 and put them to whatever sensor they are actually for. you'll need another round plug to wire in of course to connect to the sensor.

like i said its most likely temperature sensor or vtec or maybe even that egr vacum whatever it is thing, they are close by, its most likely a sensor that the wires can easily reach.

 

ya homie u missin the purge valve plug fuel hose sensor just take your time get a honda manual make sure everything is hooked up right just take your time hard to tell someone how to fix your prob liek that on here u have have to check all your plug sensors the works bro good luck

 

lol I was just about to point that out myself. I was like wtf why does he have 2 IAT's? You definitly have some strange things going on with your wiring. Check for codes then figure out which sensor your computer is reading and remove the other one by unpluging one at a time to figure out which one throws a CEL. Use the one in the manifold.

I would also be willing to bet that something is throwing a CEL already and maybe someone took the bulb out to fool you into thinking there was no wiring problems.

 

could be... ill check tomorrow

 

It looks like the hanging wiring would go to the sensor you pointed out that doesn't have anything plugged in to it. It looks like, from whats dangling there, that an old sensor broke and you have the remains of it still plugged in. Remove that and plug it into the sensor missing a clip. That's where that lingering wiring goes IMO because it's right there and there is the right amount of slack to be plugged in there. I'm not sure about this setup, but I know some CELs on a P28 cause a limp mode that stops VTEC.. Good luck..

 

A more obvious question, what ECU are you running?

don't you just love it when someone doesn't really know what the fu*k they are doing, or just plain lazy.

I'll break it down like this. None of us started ou pulling engines and rebuilding trannys. I applaud the people who ask questions because all they want to do is learn. I'm more than willing to help those who display common sense. But people that are like "I drove my car with no oil and it stopped working, what happened?" need to be shot before they breed more complete morons.. This world already has plenty.

But I would like to see some sense of family here, you know, helping those that can be helped. Lets try being less critical of people who might just have a little less experience with this then some of the rest of us, all they want is our help. But as far as complete morons goes, FLAME ON!!

It is screwed in to the valve cover but it wont function as a ground only being attached to the valve cover like that. Its gotta go under that acorn nut right by it otherwise it isn't acting as a ground for him..

 

i appologize for my ignorance. I did not put this car together. I have not had it that long and the only things ive done to it all sit on the front bumper.

I was told the ECU was the stock gsr.

 

and no the CEL light was not taken out because it lights up when the car is turned on...

I know that the speed sensor (VSS) was a problem before... it is kind of on and off when it gives me problems... some days it will jump around some days it wont.

Does the VSS affect VTEC?

 

Go find the guy that did that and ask him wtf was he thinking....and then to you for buying a modified car and being clueles...

God seeing the 2 IATs, the ground on the valve cover, etc. GOD KNOWS what he didnt do right.

 

Sorry i dont have the time or the resources to do much... i guess im just gonna have to take it to my friend who knows what hes doing and fix it that way

they meant to check the CEL. And being told it is a stock GSR ECU is ALOT different than checking what ECU it actually is.
