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.
The sensor itself is the most common failure point. Internal short, open circuit, or contamination can cause an out-of-range signal.
The tone ring (reluctor ring) on the CV joint or hub may be cracked, missing teeth, or covered with debris, causing erratic sensor readings.
Chafed, broken, or corroded wires between the sensor and the ABS module can cause intermittent or incorrect signals.
Excessive play in the wheel bearing can alter the air gap between the sensor and tone ring, leading to range/performance faults.
Insufficient voltage to the sensor or a bad ground at the ABS module can cause erratic sensor performance.
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.
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.
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.
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.
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.
