I have a problem with the ESP ABS light.

I changed the ABS sensor and now that is good but i get

01542 - Yaw Rate Sensor (G202)
37 - 00 - Faulty

And my questions are where the YAW sensor is located?
Any tips on fixes beside changing the sensor
And can the part be changed with same sensor or does it need to be calibrated?

Here is the very first result from a Google search. You're welcome...

Thanks alot i found the sensor.

About the calibration, is it the same thing? steering angle sensor and the YAW sensor?

MrKid

Yes, readings from ABS, YAW and Steering angle all work together to control stability control.

Thanks alot.
When i get
01542 - Yaw Rate Sensor (G202)
37 - 00 - Faulty

Could the sensor have been damaged by a faulty ABS sensor? Are the wires from the ABS sensor connected to the YAW sensor?

For me faulty mean that the sensor is dead, maybe i am wrong?

Finally i got a ABS sensor from Spain that is working but maybe the wire (if it connects) to the YAW was damaged?

Any tip where to look?

MrKid

With these cars, there is no easy way to tell. You have to test each component separately to ensure they are working individually. The Ross Tech link had a diagnostic link. Follow that, and test your systems out. This is impossible to troubleshoot online.

Okey, thanks
