Rear height sensor

After replacing all the rear wishbones my Disco 3 suspension started to go into into extended mode when not moving with rear left going up i checked the Hawkeye and the corner heights are all over the place

Corner heights rr 5mm, rl 7mm, fr -8mm, fl -3mm
Level offset rr -8mm, rl 9mm, fr -7mm, fl -3mm

I changed the rear left sensor and replaces the plug complete with wires still the same readings.

Where should I check next, is there a junction box or could a wire be broken?

You should check the voltage output of the sensor before blaming it or wiring.

It may require calibration

Checked the voltages

Rr 2.08v, lr 1.95v, rf 2.17v, lf 2.17v

Left rear us a bit low but in the ball park, who would you reckomend around Falkirk/central Scotland to do the calibration

Ive got a GAP but its locked to my motor, I can read and clear codes from other motors but unsure if I can calibrate.
I'm in Cumbernauld this weekend too
