This has happened to my friend as well. Everything was kosher with my setup untill i installed the VAFC, now at high RPM's mainly in 3rd and sometimes 2nd, i get code 22 which is the VTEC oil pressure sensor. What gives? i know the VAFC is now wired in between the sensor and the ECU, is the ECU just throwing the code because it knows its not getting the proper signal? checked oil, all the basics, and everything was fine....?
Ran 100% flawless prior to installed the VAFC, yes it was done properly, and im left clueless...help!

anyone?

 

where the info at?

 

hello?

 

Search... vtec pressure switch or vafc hook up wrong "vtm" wire not cut or connected.

 

my VTM isnt connected, this i know for sure.
i have a 94 del sol S and i followed the wiring diagram according to APexi to wire in the VTM wire, after i did this, can ran like *** and i got a CEL (code 3, the map sensor) stupid diagram licks ***. obviously the wire they specified for the VTM is the wrong one,,, just like how the TPS is the wrong one as well....

What is the proper pin for the VTM signal on a 94 del sol???

 

I had a vafc in my 94 gsr and it was giving me a code 3, for the longest time I didnt know why. I took out the vafc and wholla it was gone , i was running it a 0 settings etc. but now I got hondata s200b on its way
Oh and the code 3 puts the car in crap mode

 

code 3 is map sensor,,, stupid Apexi says thats where you cut and wire in the VTM signal,,, WRONG! Trying to figure out where the VTM signal really is. Also apexi's diagram as to where the throttle signal should be is totally wrong as well...

 

You think even in my gsr I was actually tapping ino the map sensor wires?

 

yes,,, you car ran rough as **** and probably wouldnt idle,,, correct?
code 3 is the map sensor, after i reconnect it back to stock, the code went away and car ran like a champ..
Still throwing code 22 on high RPMs tho... stupid asses at apexi...

 

Oh i could idle and run it fine but it would somewhat flood the engine and bogs, but thats before I took out that crap
