Hi, my 2006 Cayenne V6 gave me today some fault codes, can someone help me with them?

Fault code P0503 & 1682 on the durametric scanner, on the dash board it has turned on the  ABS & PSM lights.

P0503 Vehicle speed sensor - no signal/above limit value

Possible cause of fault:
- No signal or faulty signal from PSM control module
- Rear right wheel speed sensor faulty
- CAN data bus faulty
- PSM control module faulty


Fault code 1682 - Speed signal, rear right wheel

Possible cause of fault
- Signal from PSM control module does not correspond to expected signal (please read out fault memory)
- Signal from PSM control module does not correspond to expected signal (implausible signal)


I would check the right rear speed sensor - replace if needed - then re-test.

Good Afternoon, I changed the ABS sensor and the PSM & ABS lights turn off.

So your advice worked perfectly. But know the 4x4 light is on. What could this be?

Thanks for your advice and prompt response.
