Hi,
I have replaced my SOHC VTEC engine (D16Y1/P28) with a JDM B16A/P30 (Serial # 5###). The ECU is throwing a CEL of 3 which indicates a MAP sensor electrical fault.
Where is the MAP sensor? It is not on the firewall (the D16Y1 had it mounted on the Throttle Body) and it is not on the TB. So, how do I fix this problem? Also, I am using the original harness from the ECU to the strut towers, and then the B16A harness from there. There is no plug connection for the MAP sensor.
It is also throwing a 14 which is the EACV, which I have replaced but to no effect.
Main symptom is the car idles at between 1500 and 2000 RPM, resulting in very poor fuel economy (300KM on a 45L tank of ULP98 octane).
I understand I have to also send a wire from the Knock Sensor to the ECU to enable the VTEC. What is the best way to do this? I tried inserting a pin in the plug but it didn't quite fit. Should I trace the KS wire through the harness and see where it ends up, and connect to there?)
My car is an Australian-delivered EH9 ('92 - '95 Civic sedan, designated VTi here in Australia).
PS. I am running a modified P30 with ROM socket but the ECU is switched to "standard" mode.
