I just finished putting in my JDM B16A into my 1995 Civic CX. One of the CEL codes I'm getting is for the MAP sensor. I know on JDM Civics the sensor is on the firewall, and USDM on the throttlebody. Can I just use one of the vacuum lines off of the intake manifold and stick the MAP sensor from the old CX engine on it and mount it somewhere for stability? Seems logical enough but I thought I'd ask first.

 

Sure, all Honda MAP's operate in the same voltage range to my knowledge. Just don't T off that vacuum line, I learned the hard way that Honda MAP sensors like to run on their own line.
