Look at that - a systematic way of figuring out why VTEC doesn't work. After reading so many of these threads around here, I was beginning to think visual inspection followed by randomly replacing parts and hoping for the best was how it was done.

Good post.

HondaPartsHero · 11-16-2006, 12:24 PM

let me know if people like this and I'll post OBD2 shots as well

EE_Chris · 11-16-2006, 02:35 PM

I like it. I got it bookmarked. Do the OBD2 stuff so we have a central place for both gens.

HondaPartsHero · 11-18-2006, 10:43 AM

added OBD2

I guess I will toss it out there as well for the JDM owners that do not have Vtec Pressure Switches and want to run USDM ECU's. Splice the Vtec Solenoid wire (Green wire with a yellow stripe) and Vtec Pressure Switch wire (Blue wire with a black stripe) together and this will fix it.

I'd love to see the IAB sheets for OBDI if you have them. Otherwise it's great!

Azn Kenny · 01-12-2007, 10:43 AM

Nice find.

HondaPartsHero · 01-12-2007, 03:36 PM

yeah I can get it up later for the IABS

HondaPartsHero · 01-13-2007, 07:43 PM

added IAB trouble shooting, OBD1

Also is it possible to change the title to "My VTEC/IAB doesn't work" to reflect the updates?

g2_teg_ · 04-02-2007, 06:49 PM

will this be needed at all if im not getting a CEL?

MHBb16CRX · 06-02-2007, 07:49 AM

HondaPartsHero · 07-07-2007, 08:20 AM

Mattb16teg · 04-14-2008, 02:10 PM

travis-b16a2-eg · 04-14-2008, 06:45 PM

bump this, very useful... if you don't have a manual.

Nachos · 10-03-2008, 11:53 AM

very useful, Thanks! I just got a new multi-meter. so test the soleniod do I use DC or AC settings? is there a general rule of thumb where if there's X amount of wires then its a AC/DC?
Thanks! still new at this

racebucket_eg · 10-13-2008, 09:17 AM

Very helpful. Thanks

What is the manual referring to when they say "connect the ECU test harness"??
