When things get unstable: Why defective acceleration sensors become a safety risk

A vehicle suddenly behaves unstable in a bend, the ESP does not intervene – the ABS/ESP warning lamp lights up in the cockpit. Sounds familiar? In the workshop it quickly becomes clear: the fault lies in the vehicle dynamics system, or more precisely in the longitudinal or lateral acceleration sensors.

These small but crucial vehicle sensors provide the data basis for systems such as ESP, ABS and traction control. If a sensor fails, a routine journey becomes an incalculable safety risk.

VEMO sensors for top-level driving stability

VEMO longitudinal and lateral acceleration sensors are the tested solution for workshops that want to play it safe – and give their customers back a familiar driving experience.

The VEMO sensors deliver ultra-precise measured values, are robust against vibrations, moisture and temperature fluctuations and fulfil the highest requirements – many in OE quality. Thanks to extensive testing at the VIEROL Academy and strict quality controls in accordance with ISO/TS 16949, we guarantee a sustainable repair – and a good feeling on every journey.

The technology behind the VEMO sensors – what do longitudinal and lateral acceleration sensors do?

These acceleration sensors record the movements of the vehicle along two axes:

• Longitudinal axis (acceleration / braking behaviour)
• Transverse axis (cornering / drift)

The measurement data is transmitted to the control unit in real time and is essential for the function of the electronic stability control (ESC), ABS, traction control and other driver assistance systems. They ensure that the vehicle remains stable and safe even in critical moments.

Warning signs: How to recognise defective sensors

The following symptoms may indicate a faulty longitudinal or lateral acceleration sensor:

❌ ESP/ABS warning light in the cockpit
❌ Unstable cornering behaviour or delayed ESP intervention
❌ Error messages in the on-board computer (e.g. readable via OBD)
❌ Implausible acceleration or speed displays

Timely replacement is crucial – for greater safety and satisfied customers.

Causes for the failure of acceleration sensors

Longitudinal and lateral acceleration sensors are extremely stressed components. Common causes of a defect are:

❌ Mechanical damage (accidents, strong vibrations, off-road use)
❌ Electrical problems (faults due to corrosion, cable breaks or short circuits)
❌ Extreme temperatures or humidity
❌ Material fatigue
