I picked up a sensor for logging fuel pressure and I was going to build a small 5V power supply with a voltage reg for it but just had another idea. Is there any down side to tapping the 5V feed to the TPS or MAP sensor from the ECM and using that to power it? Current draw should be very low (10mA max) so as long as the ECM drivers aren't borderline in their output I'm guessing it should work. Any comments?
Here's a link to the sensor.
