SR20DET CAS voltage check?

[Dyl510]

Just hoping someone can give me the procedure to checking for proper readings from the CAS on an S13.

I assume it's similar to the MAF and TPS, just a matter of probing certain wires and turning the engine over and checking for proper voltage outputs. Can't seem to find one single internet writeup on how to do it properly.

Cheers!!!!

No it's not similar to a TPS or MAF. It's a wave(square IIRC). You need an oscilloscope if want to see it. But you can check the voltage input and the ground of the CAS with a multimeter.
