Known JLR Fault
Range Rover Sport EAS Height Sensor Fault — Causes & Fix
Affects
Overview
The Electronic Air Suspension (EAS) height sensors on the Range Rover Sport measure ride height at each corner and feed data to the suspension ECU. When a height sensor fails or its linkage breaks, the system receives incorrect height data — causing the suspension to behave erratically, throw fault codes, and in some cases refuse to adjust ride height at all.
Symptoms
- ▶Air suspension warning light on dashboard
- ▶Vehicle sitting incorrectly — one corner higher or lower
- ▶EAS refusing to enter off-road height modes
- ▶Suspension adjusting erratically or continuously hunting for correct height
- ▶Height sensor fault code stored in the EAS ECU
- ▶Motorway mode or off-road modes unavailable
What Causes It?
- ✕Height sensor linkage ball joint breaking — plastic ball joints are fragile
- ✕Height sensor potentiometer wear causing intermittent readings
- ✕Corrosion on sensor wiring loom connector
- ✕Physical damage to sensor from off-road use or stone strike
The Solution
JLRMAN diagnoses EAS height sensor faults using SDD, reading live ride height data from all four sensors to identify which is faulty. Physical inspection of the sensor linkage is always carried out — broken linkage ball joints are a very common cause. Sensor and linkage replacement is straightforward and we calibrate the EAS system after any sensor work.
How to Prevent It
Inspect height sensor linkages annually — the plastic ball joints are inexpensive to replace when caught early and prevent erratic suspension behaviour.
Common Questions
