The 2013 Honda Accord uses four wheel speed sensors for its ABS system—one at each wheel. This means there are four sensors in total, feeding data to the anti-lock braking system to monitor wheel speed and help control braking during a skid or stop.
Wheel speed sensors, sometimes called ABS sensors, measure how fast each wheel is rotating. The ABS control module uses that data to determine if braking pressure should be reduced on any wheel to prevent lockup. In most 2013 Accord models, there are four wheel speed sensors, positioned at the front-left, front-right, rear-left, and rear-right wheel hubs.
Where the sensors are located
The sensors are mounted at each wheel hub and are connected to the ABS control unit via wiring. Here is where you’ll typically find them on a 2013 Accord:
- Front left wheel hub assembly
- Front right wheel hub assembly
- Rear left wheel hub assembly
- Rear right wheel hub assembly
In practice, each sensor is positioned to monitor the rotational speed of its corresponding wheel, feeding data to the ABS module for real-time braking decisions.
Maintenance notes and diagnosis
If you experience ABS or traction control warning lights or abnormal braking behavior, the issue is often related to wheel speed sensors or their wiring. Common considerations include:
- Inspect sensor tips and wiring for damage, corrosion, or dirt near the wheel hubs.
- Check for fault codes related to wheel speed sensors with an OBD-II scanner.
- Replace the sensor or associated hub assembly if data from a wheel shows inconsistent speed readings.
- Remember that some repairs involve replacing the wheel hub assembly that houses the sensor, especially on older or high-mileage cars.
Proper diagnostics require confirming that the sensor outputs are within specification and that the wiring between the sensor and ABS module is intact.
Summary
The 2013 Honda Accord employs four wheel speed sensors, one at each wheel, to feed the ABS system. This setup enables independent monitoring of wheel rotation and helps the car prevent wheel lock during braking. Regular inspection of wheel hub areas and wiring can help prevent ABS-related issues.
