Wheel speed sensor intermittent was created by JohnJas
Hi everyone,
I have a VW Golf mk6 cayc with codes  01279(longitunidal acceleration sensor adaptation), 01435 (brake pressure sensor 1 adaptation), 00778(steering angle sensor adaptation), 01423(lateral acceleration sensor)
My main concerns are= 01314 (engine control module read trouble codes - intermittent), 00285/00283 (left/right wheel speed sensors G45 electrical problem intermittent), 00668 (supply voltage terminal 30 upper/lower limit reached - intermittent) and finally 01305(databus for infotainment - no signal/no communication)  

The wheel speed sensors on this car I think it's a magneto resistive active sensor. It's a two wire sensor 1x is ground wire and 1x is both power supply and signal. Would like someone to direct me on where to find testing methods for this type on scanner danner premium. Thank you

The signal wire of a magnetoresistive sensor will produce a very small (about 500mv +/-) squarewave when the wheel spins.

The good thing about wheel speed sensors is there is usually four of them.
You can do all the checks your heart desires on a functioning one and compare results to non functioning one.
