Map sensor/ECU.
Can somebody tell me which way the current flows? Does it go from the ECU to the MAP, or the opposite? Thanks.

uhh...what? 5v is provided at the MAP any time the ignition is on, it is grounded as well. depending on manifold pressure there is a voltage output to the ecu.

Re: Map sensor/ECU.
Yeah yeah, I'm scratching my head too. Thanks.

5v is coming from the ECU, that's all I wanted to know.
