ABS light on randomly

[toyotavios_11]

Model 2011 yaris sedan.

ABS light comes on randomly after some distance of driving and the wheel turns hot.

The light will eventually come off after stopping for a few moments and the wheel temperature get colder.

Or clear the code using OBD2 scanner.

Pull the code and get DTC C1402 "Malfunction in Front Speed Sensor LH Circuit".

Already tried to clean both ABS sensor tip and ring sensor, but error is still on and off.

Does this mean i have bad ABS sensor?

I have the same issue I already changed the bearing for a genuine one, I’ve already changed the speed sensor and the code still showing so abs light and the traction control light still on even when I cleared the codes many times, I don’t know what else to do.

Look carefully for a cracked tone ring.
