Description
Siemens Acceleration Sensor for Peugeot 307 vehicles
High-quality Siemens acceleration sensor designed for Peugeot 307. This genuine-style sensor is commonly referenced under part numbers 9648829080, 5WK42989 and 8216AL, making it easy to find by code when you search. The unit measures vehicle acceleration and supplies reliable input to stability and safety systems, helping ABS/ESP controllers and other control units respond correctly during dynamic events.
Function And Benefits
The acceleration sensor detects longitudinal and/or lateral acceleration forces and converts them into an electrical signal for the vehicle’s electronics. Accurate data from this sensor is essential for traction control, stability intervention and safe deployment logic in safety systems. For professional mechanics and competent DIYers, replacing a faulty sensor restores correct sensor readings and helps eliminate related fault codes.
Technical Information

When searching or ordering, use the referenced product codes (9648829080 / 5WK42989 / 8216AL) — customers and workshops often locate the correct part by these numbers. Compatibility can depend on model year and vehicle equipment; check part numbers against the vehicle’s parts list before installation.
Typical Failure Causes
- Moisture Ingress Or Corrosion Leading To Electrical Faults
- Mechanical Shock Or Impact Damaging Internal Sensors
- Wiring Harness Or Connector Damage Causing Intermittent Signals
- Age-Related Electronic Component Degradation
Replacement Procedure And Recommendations
Replacement is straightforward for a trained technician or experienced DIYer with basic tools. General steps:
- Disconnect The Battery Before Starting Work To Avoid Short Circuits.
- Locate The Existing Sensor — It Is Often Mounted On The Vehicle Body Or Central Tunnel Area; Remove Any Trim Necessary To Gain Access.
- Unplug The Electrical Connector And Unbolt The Sensor From Its Mounting Bracket.
- Install The New Sensor In The Same Orientation As The Old Unit; Secure Bolts To Specified Torque Values And Reconnect The Connector.
- Reconnect The Battery, Clear Related Fault Codes Using A Diagnostic Scanner, And Verify Sensor Operation During A Road Test.
Important Tips: Keep The Sensor Orientation Identical To The Original Unit; Contaminants And Incorrect Mounting Can Produce Incorrect Readings. After Fitting, Use A Diagnostic Tool To Clear Fault Codes And Confirm Live Data; This Ensures The Replaced Unit Is Communicating Correctly With The Vehicle Systems.
Why Replace This Part
Faulty acceleration sensors can trigger stability control warnings, degrade handling performance or generate persistent error codes. Symptoms include ABS/ESP lights, unexpected stability interventions or diagnostic trouble codes referring to acceleration inputs. Replacing the sensor typically eliminates these symptoms when the underlying cause is a failed sensor.
Order this Siemens acceleration sensor for a reliable replacement part that is widely referenced by the OE numbers listed. Perfect for garages, fleets and skilled enthusiasts working on Peugeot 307 vehicles.
