Re: Scenic 11 ABS
The sensors are electrically passive. All they are is a
, wound round a magnet. The ABS ring castellations cause a minute electrical pulse in the
. Typically an ABS sensor is about 100 Ohms resistive. SO... one can check them with a mutimeter. There's not always voltage at the sensor, that ONLY needs to be there at start up, when the system checks they are connected.
After that, it relies on the pulses. Which are effectively AC (Alternating current), which you can measure, but only when the wheels are spinning
You are only young once, but you can be immature forever
