i just put in my friends 94 gsr ecu into my 93 hb which has a 96 b18c swap. when i put in his ecu, code 22 came up which is the vtec pressure valve. i've read that it could be low oil pressure, however, a couple hours prior to putting in the ecu, i changed my oil.

i've also read something about oil pressure switch or something, but what is that and where is it located?
can anyone else pinpoint the problem and how i can fix it?

 

ok heres what i found and i really think this might work.

however im still unclear and how to connect A4 to D6?

 

<FONT COLOR="royalblue"> Did you even bother to check to see if do have the Oil Pressure Sensor, before you jump to conclusion. Which ecu were you using before? Which Harness are u using now? OBD2?</FONT>

 

no i dont think i have it because ive just read that jdm and edm models 96+ dont have the oil pressure sensor. i was using my chipped p28 before and am using the obd1 harness.

so im guessing i have to splice D6 to A4 but i have no idea how to do this.
can someone post up a pic of the pin layout?

 

yeah i checked. i dont have that green thing that comes out from the vtec solenoid.
bump cuz i have state ref tomorrow.
someone please help.

<FONT COLOR="royalblue"> Open your hood & check. It's a Big Green Plug. Before you go do any splicing. If you don't have the sensor, that means u have a plug hanging somewhere, just get the sensor and put it on.

i've aleady found that thread. but thanks though.
also one more question: do u just twist on the oil pressure switch?

im trying to borrow my friend's oil pressure switch and i was wondering if i could just twist his off and put it on mine.
