Starting a new thread. I'm new to trying to diagnose faults on our lovely 206 cc.
We've just had the exhaust replaced, MOT. When you start driving though it shows ABS fault. The car drives fine and the brakes work :-).
I suspect a sensor fault but would like to know. I got a cheap ODB2 scanner. Using an android app called Car Scanner. It reports two things:
PO502 Control Unit 10 Vehicle Speed Sensor (VSS) low input
PO133 Control Unit 10 Heated oxygen sensor (HO2S) 1, bank 1 - slow response
Neither of these seem to have any bearing on the ABS fault?
There is an option in the scanner to send extended read codes but it says "at your own risk" so I'm a bit nervous.
Any insight on the above welcome before we head to our normal garage.

Re: "ABS Fault" and OBD2 query
P0502 can be an ABS sensor depending on speedo drive type. See if any of them are open circuit with a meter

It was a sensor fault and fixed by our nice garage.

A lot of OBD readers don't display the correct codes ... Peugeot/Citroen have a slightly hybrid system and bury some in the BSI which OBD can't read. Plus many are based on OBD2 which is fine for US cars or cars imported to US but Europe uses EOBD which is a derivative and some parts re-coded. Hence .. it can make mistakes..
