pr3 ERROR "code 17" VSS issue
 

I got b16a pr3 ecu and my vtec doesnt kick in..........
VSS i guess is causing issue. How do i correct this issue?
I have a 94 gsr gauge cluster in place of the original.
any help please
thanks

Re:pr3 ERROR "code 17" VSS issue
 

well does your speedo work? that could be cousing it ::)

YES it will couse VTEC not to kick in...

Re:pr3 ERROR "code 17" VSS issue
 

and which car is this in!?!? some details, motor swap, wiring changes, tranny? give us all the info man.

Re:pr3 ERROR "code 17" VSS issue
 

Ok i got a 88 civic hb.
It has a b16a sir engine. PR3 is written on the head and the block just says b16a on it.

I have a 94-01 GSR gauge cluster in it. I am not sure which tranny it is but when i am going 80 miles an hour it's running 4500rpm on the interstate.

My speedometer does work. But it seems to be intermitent.
But even when it is working my VTEC does not start.

I usealy get the check engine light when i am in 5th gear.
I can restart the car and the light goes away.

But i still got CODE 17 when i look at the ecu.

Re:pr3 ERROR "code 17" VSS issue
 

i bet it has to do with your cluster. use the orignal cluster with the car and see if it goes away. I bet there is a sensor on the back of the orignal cluster and the ECU doent understand the signal.

Sensor on the back of my 88 DX cluster?
That thing was realy shitty. I got 9000 redline on my gsr, but i will try it. I gotta go pick one up from a junkyard. I threw mine away.

Re:pr3 ERROR "code 17" VSS issue
 

correction, the CEL on the cluster goes off, the ECU is still throwing the code. you need to reset the ECU for the code to be gone. pull the hazard fuse (in the fuse box under the hood) for a minute, put it back in then go rip up and down the street for a minute. i will bet VTEC works till the light comes back on....

Re:pr3 ERROR "code 17" VSS issue
 

I tried that. It still didnt help.

But i did take a WIRE and run it from my battery to my vtec solenoid while my friend held down the gas to 4000. And BAM you can hear it kick in no problem.

Just it seems the damn ecu sends now power to it.

Re:pr3 ERROR "code 17" VSS issue
 

don't you mean 8200 redline

Re:pr3 ERROR "code 17" VSS issue
 

Well to be correct my GSR cluster doesnt go to 9000 it goes to 9500. My ecu did limit me to 8200 before i got a chip off ebay. I have no limit now.

Re:pr3 ERROR "code 17" VSS issue
 

wait? you shipped the ECU?? put the orignal one back in and use that and see ifthe problem goes away. i dont trust the chips on ebay worth a ----.

Re:pr3 ERROR "code 17" VSS issue
 

well the eGAY chip is prolly the culprit, also, if the rev limit is changed (via chipping the ecu), i doesn't matter which cluster you use, you will still be able to rev to whatever it is set at. and i sure as hell hope your not really revving to 9500 ;)

Re:pr3 ERROR "code 17" VSS issue
 

Yeah i know everybody hates on the ebay.......
But guess what already tried another ecu from my friends car same freaking issue. And i am not revving to 9500 lol
I have took to 9000 on the track before though.

Is there a way i can trick this VSS?

Re:pr3 ERROR "code 17" VSS issue
 

---- it, just run a wire from the solenoid to an accessory fuse in your fuse box ;D

Re:pr3 ERROR "code 17" VSS issue
 

Well having the VTEC solenoid on all the time, doesnt sound to healthy.

Re:pr3 ERROR "code 17" VSS issue
 

well, you said it kicked in like normal when you had it hooked to the battery right? if so then it wouldn't be on all the time, it sounds like it may be getting the rpm reading when to engage, maybe just not getting power, i wonder if you can check it with a votmeter.

Re:pr3 ERROR "code 17" VSS issue
 

No i only had my friend rev it up to 4000, So i could hear it KICK in. It will come on anytime there is a 12+ source going to it. Plus vtec works in stages and with that plugged up it will be on through the whole RPM range .


No VSS signal will stop the ECU from engaging the high cam lobes for the B16A. I wish i knew a way to trick that bastard.

Re:pr3 ERROR "code 17" VSS issue
 

here are some pics of my engine and my intake manifold
That has vaccum lines that need to be hooked up and i dont know where they go.

Re:pr3 ERROR "code 17" VSS issue
 

has this always been a problem or only since you installed something?>

what VSS on the tranny do u have??

88-91 use a cable driven VSS and 92+ use electronic.

Re:pr3 ERROR "code 17" VSS issue
 

Hey guys i got it fixed

I use a electric vss becuz of my GSR gauge cluster

All i had to do was rewire my vss

I had one wire as ground
One wire going to ecu
and one wire going to the speedometer

Well all i had to was make one wire split going to the ecu and the gauge clusters orange wire

and then run the other to the ignition

and ground stayed where it was

bam got VTEC

what what
