Dodge Charger / Chrysler 300 / Magnum 2005–2010 steering angle sensor
What the steering angle sensor does on these LX-platform cars
On the 2005–2010 Dodge Charger, Chrysler 300 and Dodge Magnum, the steering angle sensor measures the position and rotational movement of the steering wheel. The electronic stability control system uses this signal to compare the driver’s intended direction with the vehicle’s actual yaw and lateral acceleration. The sensor data also supports other networked functions where present, but its primary job is stability control input.
Scope and model-year qualification
The core answer applies to the 2005–2010 rear-wheel-drive LX-platform cars covered here: Dodge Charger, Chrysler 300 and Dodge Magnum. The steering angle sensor is not always a separately replaceable item that you can buy on its own. On many of these vehicles the sensor is integrated into the clockspring assembly behind the steering wheel, so repair often means replacing the complete clockspring and sensor unit. Variant-dependent behavior can differ by trim, stability control option and market calibration, so the replacement part should be matched to the exact model year and equipment.
Location and common failure symptoms
The sensor is located in the steering column area, typically behind the steering wheel and near or inside the clockspring. Symptoms of a failing or uncalibrated steering angle sensor can include an illuminated electronic stability control warning lamp, a traction control light, or a service stability system message. The vehicle may also store a diagnostic trouble code related to steering angle signal plausibility, calibration or internal failure. These symptoms do not automatically prove the sensor is defective; wiring, terminal tension and calibration issues can produce similar warnings.
Calibration after repair or alignment
A new or disturbed steering angle sensor generally requires calibration so the stability control module can learn the straight-ahead position. This is often done with a compatible scan tool through the steering angle sensor or ABS/stability control module. Some systems may also allow a relearn procedure after driving under specific conditions, but a scan-tool calibration is the standard service approach on these cars. If the sensor is not centered correctly after a steering wheel removal or alignment, the ESC system can interpret straight-line driving as a steering input.
Replacement guidance and material uncertainty
Before replacing the sensor, confirm the exact part type for the vehicle. On models where the sensor is integrated with the clockspring, the replacement unit includes both components and must match the original equipment configuration. Documented repair procedures generally require disconnecting the battery and following the supplemental restraint system safety steps before removing the steering wheel and column trim. Because part designs and service procedures changed during the 2005–2010 production run, a replacement guide should be checked against the specific model year, trim and stability control option. Material uncertainty includes wiring faults, connector problems and incorrect calibration that can mimic a failed sensor.
Next action
Start by reading the stored diagnostic trouble codes with a scan tool that can access the ABS or stability control module. If the code indicates a steering angle sensor issue, check the wiring and connector before condemning the sensor. After any replacement or column work, perform the calibration routine specified for that model year. If the exact calibration or replacement procedure for your specific trim is not available, treat that as a gap and seek the manufacturer service information for the vehicle before proceeding.
