Any luck with this? Did you resolve it?
I have had the same problem for quite a while. The code reader showed an open circuit on the driver side rear speed sensor. Had it changed, codes cleared and nothing changed. The ABS lights (and all associated EPS, inflation etc.) come on fairly regularly however it seems to be more problematic in damp weather.
Update - I had the voltage checked for all four corners of the car, from the wheel speed sensor plug coupler to the ABS module coupler. One of the three circuits (OSR) is only delivering 8 volts.
I should add that what was previously an intermittent fault is now a permanent fault. I suppose that the lower voltage is well outside of the tolerance for wheel speed detection system.
Given the connection to wet weather I can only imagine that this is corrosion related.
I had the wiring harness exposed and partially traced but no obvious damage was found.
Does anyone have a wiring/ routing diagram for the 2013-2022 Peugeot Blue HDi Allure?
I'm not convinced that we haven't missed an intermediate plug coupler.
Does the harness pass through the firewall in one piece or is it plug coupled between either side?
Anyone have any previous experience or photos that might help?
Thanks
