Description
Double kinetic ESP sensor ATE for Citroën and Peugeot vehicles.
This ATE kinetic ESP sensor is an OEM-compatible safety sensor designed for Citroën and Peugeot ABS/ESP systems. It is commonly referenced under the part numbers 9641342980, 10.0985-1101.4 and 454910 and is frequently searched by mechanics and DIY enthusiasts by these codes. The sensor’s role is to deliver reliable wheel/vehicle motion data to the ABS/ESP control unit, helping to maintain traction and vehicle stability under braking or dynamic maneuvers. Ideal for professional workshops and competent home mechanics who want a direct-fit replacement that restores correct ESP functionality.
Technical Information
- Manufacturer: ATE
- Model: Citroën C2, Citroën C3, Citroën C3 Pluriel, Citroën C5, Peugeot 1007
- Product Codes: 9641342980; 10.0985-1101.4
- Additional Numbers: 454910
Function And Benefits
The sensor measures kinetic/rotational movement data required by the ABS/ESP control unit to calculate slip, wheel acceleration and vehicle dynamics. A correctly functioning sensor reduces stopping distance in emergency braking, prevents wheel lock-up and enables traction control interventions. Benefits include direct-fit installation, clear identification by OEM codes for easy procurement, and restored ESP/ABS reliability after replacement.
How To Replace
Replacement is straightforward for a trained mechanic or an experienced DIYer. Typical steps:
- Park the vehicle on a level surface, engage the parking brake and disconnect the negative battery terminal to avoid electrical faults.
- Lift the vehicle safely and remove the wheel to access the sensor location at the hub/knuckle (location may vary by model).
- Unplug the sensor electrical connector and remove any retaining clips or routing fasteners.
- Remove the sensor retaining bolt(s) and extract the sensor from its mounting bore. Clean the mounting area of rust and debris.
- Fit the new sensor, ensuring full seating and correct orientation. Replace any sealing boots or clips as required and secure the connector.
- Reinstall the wheel, lower the vehicle, reconnect the battery and perform a test drive. Clear any stored fault codes with diagnostic equipment if available and verify ABS/ESP warning lamp behavior.
Installation Recommendations
- Inspect the sensor mounting bore and tone ring/reluctor for corrosion or damage before installation.
- Do Not Overtighten Retaining Bolts; secure them to a snug fit and follow vehicle manufacturer torque values where available.
- Protect the sensor cable from sharp edges and heat sources; use original routing and clips to avoid chafing.
- Clean mating surfaces and, if applicable, apply a light film of dielectric grease to the connector to prevent corrosion.
- After fitment, clear fault codes and perform a short road test to confirm the ABS/ESP lamp is extinguished and systems operate normally.
Most Common Failure Reasons
- Corrosion And Dirt Ingress: Road salt, water and brake dust can cause sensor or connector corrosion, degrading the signal.
- Physical Damage: Impacts from curbs, stones or improper handling during brake or suspension work can break the sensor or tone ring.
- Wiring And Connector Faults: Chafed cables, broken cores or corroded connectors create intermittent or no signal to the ECU.
- Reluctor/Tone Ring Damage Or Contamination: Damaged or contaminated tone rings produce incorrect readings and trigger ABS/ESP faults.
- Age And Environmental Wear: Over time seals and protective boots can degrade, allowing moisture and dirt to reach the sensing element.
When ABS/ESP warning lights appear or you experience inconsistent braking/traction control behavior, the sensor and its wiring should be among the first components to inspect. This part is widely identified by the numbers listed above, making it easy to locate and order for Citroën and Peugeot models.
