DTC C1A04-64: Right Front Height Sensor - Signal plausibility failure: Action

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2019 Land Rover Range Rover Evoque, 2018 Land Rover Range Rover Evoque, 2017 Land Rover Range Rover Evoque, 2016 Land Rover Range Rover Evoque, and 2015 Land Rover Range Rover Evoque. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: If any height sensor fixings were slackened or found to be loose or if a height sensor was changed, the height sensor calibration procedure MUST be performed

Disconnect electrical connector to height sensor and inspect connector pins & terminals for evidence of corrosion or water ingress
If no corrosion found, disconnect harness at control module. Check for short circuits between any of the three terminals and vehicle ground
Check for electrical continuity between the two connectors for each of the three terminals
Reconnect electrical connector at control module only. Check voltages at terminals within height sensor connector (sensor not connected): voltage to sensor ground connector should be ~0V, voltage to sensor signal connector should be ~0V, voltage to sensor supply connector should be ~5V. All voltages should be within ± 0.15V. Clear DTC and retest
If no circuit faults are present, check and install new height sensor as required. Clear DTC and retest
