C1403 2013 Toyota RAV4 Code - Rear Speed Sensor Right Malfunction

C1403 indicates a "Rear Speed Sensor Right Malfunction," meaning the vehicle's system has detected an issue with the right rear wheel speed sensor or its circuit.

Common symptoms include the ABS warning light turning on, traction control being disabled, and inconsistent ABS operation during braking.

Possible causes include a faulty right rear speed sensor, damaged wiring or connectors, debris or damage on the sensor ring, or a failure in the ABS control module.

Start by visually inspecting the right rear speed sensor and its wiring for damage, use a multimeter to test the sensor's resistance, and check for proper voltage signals at the connector.

While the vehicle may still be drivable, the ABS and traction control systems may not work properly, which can affect safety in slippery or emergency braking situations.

Repairs may include replacing the faulty right rear speed sensor, repairing damaged wiring, cleaning debris from the sensor ring, or replacing the ABS control module if necessary.

The cost can vary, but replacing a wheel speed sensor typically ranges from $150 to $300, including parts and labor. Wiring repairs or ABS module replacement may cost more.

Yes, dirt, debris, or rust on the sensor or sensor ring can interfere with signal transmission and trigger the C1403 code.

Clearing the code will turn off the warning light temporarily, but if the underlying issue isn’t resolved, the code will reappear.

It depends on your vehicle's warranty status. If the powertrain or ABS system is still under warranty, the repair might be covered. Check with your Toyota dealership for details.
