I have a 92 bubble with a jdm B16 with a P72. Right now I'm missing two of the double side threaded studs to hold tighten down the valve cover. Seems the old B20 didn't take these. Got em coming from Honda. Well theres obviously air leaking through and small amounts of oil at times. My problem is that I am throwing a code 22 (Vtec Oil Pressure sensor) and we have wired this thing up atleast 3-4 different ways but we go from having a code 21 & 22 to just having a code 22 so we know the solenoid is hooked up right. My question is why is it that the 22 is still coming up? We have it wired up right, we checked the ECU pins and it dead on A4 & D6. Now I know we also have to hook up the Knock sensor, right? The question on that is will an OBD1 Knock sensor thread into an OBD0 block? Need help especially on the code 22. Thanks in advance.
