Height Sensor Operating Range Checks
NOTE:
For angles of movement beyond ±40°, the sensor signal will remain at a voltage of ~0.15V or ~4.85V, depending on the position of the sensor lever, this is normal. When the investigation is complete, install the height sensor link to the upper arm. If any fixings to the height sensor body or mounting bracket were slackened, found to be loose, or if a height sensor was changed, the vehicle ride height MUST be re-calibrated. Using the Jaguar Land Rover Approved Diagnostic equipment, clear the DTCs and perform calibration procedure - Suspension system - Height calibration
To check the height sensor operation on a vehicle perform the steps below:
- Check for water ingress around the height sensor, electrical connectors or shaft end. Check for excessive movement in the shaft in all directions. To gain access to the height sensor under investigation, raise the vehicle (ideally on a wheels-free ramp) until the suspension on the corner under investigation is at full extension. Access may be further improved by removing the road-wheel
- Carefully disconnect the height sensor link from the upper suspension arm. Monitor the height sensor signal voltage output for the height sensor under investigation. Position the sensor arm so it is in the mid position and confirm that the voltage is around 2.5 volts. Move the sensor arm over the range ±40° around the mid position and confirm that the voltage changes smoothly between around 0.2 volts and 4.8 volts. If the voltages are incorrect or do not change smoothly, then renew the sensor
