ABS Sensor fault live readings

ericbeauchamp said:

Diagnostics indicate LH rear fault.
Live readings indicate stable voltages for other 3 sensors but LH rear fluctuates from 2.39v to 0v when idling & stationary.

Does this confirm faulty sensor?

Took it for a run.... ABS Fault is still there.
Tried to clear the fault & it wouldn't clear.
Does this point more now to a broken wire?

4065 - sensor left hand rear (sensor dc failure, broken wire, sensor impedance too high/low) Current fault.

Thanks warmers.
I take it continuity across the pins of sensor OK, open circuit bad.
Volts across feed to sensor good, no volts bad.

Update

Followed Wammers suggestion, removed LH rear sensor, connected digital meter between connector pins & wiggled entire length of cable. There was no break in continuity so thought it must be the main loom.
Before checking further, a quick inspection of the connector pins in the socket showed the two pins to be a wee bit wide.
Using long nose pliers I carefully squeezed the sockets a bit tighter.
Re connecting the sensor to the main loom had a tighter fit.
Connected to diagnostics, cleared historical fault & monitoring live data showed the voltage now to be steady at 2.37v (like other 3) with no fluctuations like before.
Wiggling the abs lead showed no change in voltage & no abs fault.

Looks like problem sorted.

Thanks to diagnostics & guidance from here... .. Problem solved.

Thanks all.
