Good morning .. the shape that I know and dreo q is the only one is with a Scaner you make a deletion of faults, things that can try that the light lights are many, it can happen that the wheel sensor cable makes false contacts and that is why the ECU does not record that the wheel turns and turns on the light, in the Scaner it will appear as a right front wheel sensor does not work (it can happen that the sensor can be The sensor can disconnect and buy its resistance value with a tester using the OHMS function .. It also has to do with the light that carries the sensor with respect to the phonic wheel, some car models do not have phonic wheel and the sensor reads by the ruleman voliyas (if you place alternative rulers it can happen to you that the sensor does not walk .. the problem is not the sensor but the sensor is not what you placed) I hope you are not dizzy and it serves you greetings ..
