Wheel speed sensors are part of the Charger’s anti-lock braking system and traction control; on most models they sit at each wheel hub. In practice, front sensors live near the front rotors behind the brake calipers, while rear sensors sit near the rear hubs. AWD variants add sensors on all four corners. If you’re seeing ABS or stability-control warnings, these are the sensors most likely involved.
Front-wheel speed sensor locations
Locations on the front wheels are typically mounted to the steering knuckle near the brake rotor; the sensor tip faces a tone ring on the rotor, and a wiring harness runs toward the engine bay to the ABS module.
- Front-left wheel speed sensor: mounted in the front left wheel knuckle, close to the rotor and behind the brake caliper; sensor tip faces the tone ring on the rotor.
- Front-right wheel speed sensor: mounted in the front right wheel knuckle, close to the rotor and behind the brake caliper; sensor tip faces the tone ring on the rotor.
Wiring typically follows the control arm or fender liner toward the ABS/ESC module. The front WSS is part of the vehicle’s ABS ring and is essential for braking stability and wheel-spin detection.
Rear-wheel speed sensor locations
Rear sensors are usually integrated into the rear wheel hubs or axle assembly, with the sensor positioned to read a tone ring on the rear rotor or hub. On AWD Chargers, both rear wheels have sensors just like the fronts.
- Rear-left wheel speed sensor: located in the rear left wheel hub/knuckle area, near the rotor or tone ring; includes a small electrical connector and a short harness that runs along the suspension toward the vehicle’s ABS module.
- Rear-right wheel speed sensor: located in the rear right wheel hub/knuckle area, near the rotor or tone ring; includes a small electrical connector and a short harness that runs along the suspension toward the ABS module.
In most Chargers, the rear WSS wiring runs along the inner fender area to the ABS control module or powertrain control module depending on the year and drivetrain; replacement typically requires removing the rear wheel and potentially the rotor or hub cover.
Model-year and drivetrain variations
All-wheel-drive (AWD) Chargers
All AWD Chargers use wheel speed sensors on all four corners. Front and rear sensors read tone rings on their respective rotors, providing data to the ABS/ESC system for traction control and stability management.
Rear-wheel-drive (RWD) Chargers
Most RWD Chargers have front and rear wheel speed sensors, with the rear sensors mounted on the rear hubs or axles. The number and placement may vary slightly by year and trim; refer to the factory service manual for exact locations.
Summary
In short, the Dodge Charger’s wheel speed sensors are mounted at each wheel hub. Front sensors live near the front rotors behind the calipers, and rear sensors sit in the rear hubs near the tone rings. AWD models have sensors on all four wheels, while most RWD models have front and rear sensors as described. If you’re diagnosing ABS or stability warnings, inspect the connectors and wiring harnesses as a first step.
