another vtec stopped working thread.

[Turbo Dave]

wired it up, but its still the same code reset the ecu waited 15 minutes still the same, its wired right is their anything else that would cause the map not to work like a bad dizzy?

and this still doesnt explain the oil light. but i get code 22 which is vtec pressure switch, but ive had that code before, and no oil light came on and it still went into vtec...

[Ralphie]

you broke something

[Turbo Dave]

you broke something

thank you captain obvious

[Turbo Dave]

i had the wires upside down im going to try this now

[Turbo Dave]

wow i just noticed those two charts contradict themselves, now im really confused.


this is off the 97 lude.

[Turbo Dave]

ok this is fucked up what is what

[Turbo Dave]

im pretty sure that the ecu has gone bad, because im not getting the right voltages to the vtec pressure switch, or the map sensor.

although i cant get the oil pressure gauge in to check and i havent changed the oil yet. so i think im going to do that first. and then start looking for a computer.

That could be a possiblity. Perhaps water somewhere shorted something out.

oh my goodness your all over the place

the 97 lude has different wire colors, but same pinout. I have a h22a4 in my 92 lude and ran into the same problem. you can use a obd1 dizzy (h23, f22, h22a1) and so forth to run the h22a4.

funny how i'm running code 41, and 3 and i get vtec on a p13.

take off your dizzy cap and make sure NO moisture is in it. take off the rotor and the cap and make sure no water is on any of the sensors.

on your map it could also be your vacuum. I still can't get my map to read right on either my h22a4 or the one from the prelude.. oh well.

do you have VAFC???

i believe thats my problem im going to work on the car tomorrow and find out.

[Turbo Dave]

ok so im trying to unhook my VAFC and rewire it straight, but its being a pain in the ass i cant figure out which is d17 lol

[NAiL05]

Why didnt you just use the pinout that came with the vafc....if its used they have the diagram on there website...10x easier and it tells you where to put the wire.

vafc came with the car wired up.

i figured it out


ok i pulled out the chip and i dont know which way it goes and i put it back in but i think i fried it putting it backwards becasue now im getting a solid check engine light?

[mozzandherb]

as long as you are throwing a code ... any code ... the vtec wont work. dont ask me why it just what i have read numerous times on here. i am ordering me a new VSS and TPS tonight off ebay which will hopefully fix my problems. but good luck to you oh and just so you know the blue wire goes to the ECU and the black wire goes to ground

huh? I was throwing a "fuel system delivery" code and my vtec still worked, is what you are saying true? Any code and your vtec won't work? I don't know about that
