Ive search for weeks and have not found an answer. Im wondering if anyone knows how much current in amps our Gs draw to the yaw rate sensor. I have a 2006 g35 6mt and am about to put in a switch to disable the yaw. I have my eye on this nice led one thats small enough to mount in a ver small space in the center console. Its 12 volts and rated for 5amps im wondering if thats enough because i dont want to fry my orange power wire to the yaw like ive read so many do. Anybody have any idea what the yaw draws in current?

 

The power circuit feeding the ABS controller (which then feeds the yaw sensor) is on a 10amp fuse.

I imagine the yaw sensor has VERY little current draw though, when I've cut these things apart in the past all they are is a little plastic disc with a bunch of black lines printed on it, magnetized (or just weighted, automotive ones are probably just weighted) on one side like a compass and suspended so it's floating. Then there is an LED on one side of the disc and the light is read by the pickup on the other side of the disc, it basically "watches" the movement of those lines printed on the disc.

As you spin the sensor the disc in the middle stays in the same orientation even though the housing is being moved. This is also why you can't use an impact driver when installing these things and need to handle them like a crystal wine glass anytime they're outside the vehicle, they are INCREDIBLY delicate.

My guess is it draws less than 1 amp since it's usually just an LED light and some minor electronics. I have never tested current draw on it though.

 

Without looking it up I would agree with Cleric that it's in the milliamp range. I did try to look it up though and could only find the datasheet for the current version of the Bosch yaw rate sensor, which looks similar and has a similar part number. It draws 130mA.
