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.

Thanks

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.

Hi I have something similar but different 

I have the psm light and phc light come on instantly 

ive researched and checked the wiring near foot LHS and I actually didn’t find any previous joins like some others I’ve seen corroded, my wiring was dry also, I also researched that it could be the brake light switch but my lights are working and like someone else my switch isn’t where it should be, I did find that someone asked the same thing about where his switch is but the answer was written on a different post which I couldn’t find, if someone could help it would be much appreciated 

Id like to ad that I used my obd but those faults won’t show so I can’t get a computer reading to help me

thanks
