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.

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

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!

added IAB trouble shooting, OBD1

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

Very helpful. Thanks

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