C0507 — Right Front Wheel Speed Sensor Rangeperformance

Generic OBD-II · all makesChassis

C0507 indicates that the right front wheel speed sensor signal is out of the expected range or not performing correctly. This code is set by the ABS/ESC control module when the sensor reading deviates from the expected pattern, often due to a faulty sensor, damaged tone ring, or wiring issues.

Symptoms

What causes it — most likely first

1. Faulty right front wheel speed sensor

The sensor itself is the most common failure point. Internal short, open circuit, or contamination can cause an out-of-range signal.

2. Damaged or contaminated tone ring

The tone ring (reluctor ring) on the CV joint or hub may be cracked, missing teeth, or covered with debris, causing erratic sensor readings.

3. Wiring or connector issues

Chafed, broken, or corroded wires between the sensor and the ABS module can cause intermittent or incorrect signals.

4. Wheel bearing play or hub damage

Excessive play in the wheel bearing can alter the air gap between the sensor and tone ring, leading to range/performance faults.

5. Low battery voltage or poor ground

Insufficient voltage to the sensor or a bad ground at the ABS module can cause erratic sensor performance.

6. ABS module failure (rare)

In very rare cases, the ABS control module itself may have an internal fault that misinterprets a good sensor signal. This should only be considered after all other causes are ruled out.

How it's diagnosed

  1. Connect a scan tool and read the live data for the right front wheel speed sensor while driving slowly. Compare to other wheels.
  2. Visually inspect the sensor and its wiring for damage, corrosion, or loose connections.
  3. Check the tone ring for cracks, missing teeth, or debris through the sensor mounting hole or by removing the wheel/hub.
  4. Measure the sensor resistance with a multimeter (typically 1-2 kΩ for passive sensors, or check for AC voltage output while spinning the wheel).
  5. Inspect the wheel bearing for excessive play that could affect the air gap between sensor and tone ring.
  6. If all else passes, perform a wiggle test on the wiring harness while monitoring the sensor signal to find intermittent faults.

Frequently asked

Can I still drive the car with a C0507 code?

Yes, you can usually drive the vehicle, but the ABS and traction control systems will be disabled. The standard braking system remains functional. However, driving in slippery conditions is not recommended.

Do I need to replace the wheel speed sensor?

Not necessarily. The sensor itself is the most common cause, but wiring issues, a damaged tone ring, or a faulty ABS module can also trigger this code. Proper diagnosis is required before replacing parts.

Is it safe to replace just one wheel speed sensor?

Yes, it is safe to replace only the faulty sensor. However, if the sensor is part of a hub assembly, you may need to replace the entire hub. Always use a quality part that matches the original specifications.

Could the ABS module (PCM) be the cause of C0507?

It is very unlikely. The ABS module rarely fails and is almost never the cause of a wheel speed sensor range/performance code. Many drivers are incorrectly told to replace the module; this should only be considered after thoroughly testing the sensor, wiring, and tone ring.
