Description
Kinetic ESP Sensor TRW for Peugeot 407
High-quality TRW ESP sensor designed as a direct-fit replacement for Peugeot 407 stability control systems. This ESP (Electronic Stability Program) sensor monitors vehicle dynamic behavior and provides critical input to the ABS/ESP control unit to maintain directional stability in emergency maneuvers. Ideal for professional workshops and competent DIY mechanics who search by product number — this part appears under several reference codes commonly used in parts catalogs.
Why Choose This Sensor
This TRW ESP sensor delivers reliable signal feedback for the vehicle’s stability system, restoring correct ESP/ABS operation after a fault or collision. Purchasing the correct sensor by code ensures plug-and-play electrical and mechanical fitment in most Peugeot 407 applications. Using the right unit helps avoid intermittent ESP warnings and unwanted system interventions while driving.

Function And Application
The sensor supplies the ESP/ABS control unit with information about vehicle dynamics required for traction and stability interventions. When functioning correctly, it helps the system decide when to apply selective braking and engine torque reduction to stabilize the vehicle. This component is not normally a wear item but is essential for safe operation of the electronic stability system.
Replacement Procedure (Overview)
- Always disconnect the vehicle battery before beginning work to prevent electrical damage.
- Locate the sensor (location may vary by model/year; often mounted near the ABS/ESP hydraulic unit or within the vehicle interior close to the centre console). Remove any trim panels or fasteners to access the unit.
- Unplug the electrical connector and remove the mounting fasteners. Compare the new sensor to the old unit before installation.
- Install the new sensor, secure mounting bolts to manufacturer specification, reconnect the electrical connector and reassemble trim panels.
- Reconnect the battery and clear any stored fault codes with a diagnostic tool. Perform ESP/ABS calibration or initialization as required by the vehicle manufacturer.
Installation Recommendations
- Use appropriate hand tools and respect torque values specified by Peugeot when tightening fasteners.
- Protect connectors from contamination and ensure contacts are clean and dry before reconnecting.
- After replacement, run a full diagnostic session and perform sensor initialization/calibration with a PSA-capable diagnostic tool (DiagBox or equivalent) to ensure correct operation of the stability system.
- If you are unsure about calibration steps, have the final setup performed by a trained technician with the correct diagnostic equipment.
Reason Why The Part Most Commonly Fails
ESP sensors typically fail due to external damage (collision or impact), electrical faults (corroded connectors, short circuits), moisture ingress, or internal electronic component failure. They are not a routine wear item; failures are usually related to accidents, water exposure, or wiring/connector deterioration.
