Description
The Bosch ESP (Electronic Stability Program) sensor is a critical component designed for Citroën and Peugeot vehicles, including models Citroën C4, C8 II and Peugeot 307 II, 807 II. This kinetic sensor plays a crucial role in the vehicle’s stability control system by detecting rotational forces and aiding in maintaining directional control under challenging driving conditions.
Often identified by product codes such as 9649400180, 0265005291, and 454939, this ESP sensor is sought after by both professional mechanics and DIY car enthusiasts aiming to restore or maintain the safety features of their vehicles. The sensor connects seamlessly to the ABS and ESP modules, providing real-time data essential for activating braking force on individual wheels when slipping or loss of traction is detected.
The replacement process involves locating the sensor typically near the ABS module or wheel hub assembly depending on the specific model. Proper installation requires careful handling and occasional calibration using specialized diagnostic tools to ensure the sensor communicates correctly with the vehicle’s control unit.
ESP sensors can wear out over time due to exposure to heat, moisture, and mechanical stress, leading to faults in stability control warnings or ABS malfunction indicators on the dashboard. Timely replacement improves driving safety and avoids potential control system failures.
