Focus 2008 - Fault Code C1235 And C 1165

Is this fault likely to be in the wiring or the ABS pump ( or electronics )?

Any experiences?

A quick google says those fault codes point towards the right rear wheel speed sensor, is that the description it gives you?

I'm no expert but I'd first check the condition of the exciter ring and sensor for damage, then find out if the sensor is providing a signal to the PCM *or is it ABS module?*

Yes, it says right rear sensor 'missing input signal'. My Ford dealer will do a repair very soon. They have found so far these codes, and that the sensor is having too low voltage input. Therefore I guess that the exciter ring is out of question, so is the right rear sensor itself since it cannot do the job without it's correct operating voltage.

I fear that the abs control module supplying the voltage is bad. $$$$ :'(
