2zr MAF amperage draw, help needed

[tmontague]

Yes, until I have a chance to test the LH lightbulb fuse simply disconnecting the maf at the sensor connector will remove 80-90mA of draw. MAF's typically have a heater in always thought, so running constant power to them could cause a constant draw. Either that or they are always measuring intake temps as that is where the IAT reading comes from

Your 140mA that you had left over is the exact number I had when the ecu was still awake. Make sure you keep your probes on the baggery/terminal for over a minute. You should see the amperage drop to below 40mA at one point. If that doesnt happen after a few minutes then either the ecu is staying awake from something or something entirely different is pulling that draw.

Easy way to tell is to pull fuse "ecu-B" and then re test amperage draw with and without maf connected and see what you have.

Take note*** simply disconnecting your probes from the terminal and/or clamp will re awake the ecu as it essentially disconnects and then reconnects the battery. So will opening or closing doors or locking and unlocking them. That amperage long enough for the ecu to sleep (approx 1min) so you get proper amp draw
