This summary uses the existing diagnostic information shown in full below.
The car's computer is having trouble getting a signal from the sensor that tells it how fast the back left wheel is spinning.
This code indicates that the electrical circuit for the rear left wheel speed sensor is reporting a low voltage signal.
The wheel speed sensor monitors the rotational speed of the wheel and sends this information to the ABS control module. A 'circuit low' code typically means that the signal voltage from the sensor is lower than expected, which can affect the ABS and traction control systems.

Moderate
• Toyota Camry
• Honda Accord
• Ford Focus
• Regularly inspect wheel speed sensors and wiring.
• Avoid driving through deep water.
• Perform routine maintenance checks.
Sensor Issue
• Do not ignore ABS warning lights.
• Seek professional diagnosis if unsure.
• Ensure regular vehicle maintenance.
Check with your vehicle manufacturer for warranty coverage on ABS components.
This code has been commonly reported in vehicles with high mileage or those exposed to harsh conditions.
Moderate – While the vehicle is still drivable, the ABS system may not function correctly, which can affect safety in slippery conditions.
Driving with a malfunctioning ABS system can be unsafe. It's important to address this issue promptly to ensure vehicle safety.
• Vehicle parked on a level surface
• Ignition in the 'on' position
The wheel speed sensor is located near the rear left wheel, typically attached to the wheel hub or suspension.
Q: Can I drive with a C1207 code?
A: Yes, but it's not recommended as the ABS system may not function properly, affecting safety.
Q: How can I reset the ABS light?
A: Fix the underlying issue first, then use an OBD-II scanner to clear the code.
