MAFT diagnosis?

[Beanokid69]

So I was having a problem for a few days now, the rpm wire on my CAS is dead. (pin22 on ecu) It should put out 5v but reads about .17v when the maft rpm wire is spliced into it. (white wire from maft) ....When I remove the wire coming out of the maft and just run the CAS with no maft spliced into it, I get my 5v and my car will start....but because the maft is not installed properly to start the car it runs like crap.

I looked at the translators chip and nothing looked burnt or anything like that, I cant seem to figure out why its draining the voltage out of that wire?

What can I do to figure out whats up with it?

The wire going to the maft i would look for a chafed wire. Shorting to ground not letting voltage to get to your maft. Check you splice that could of been bad to. Good luck.
