Causes and Solutions of Toyota C1407 Code
| Cause | Solution |
|---|---|
| Rear speed sensor RH/LH | Check and replace with a new sensor if necessary |
| Speed sensor circuit | Check wiring and connectors for any damage |
| Brake actuator assembly (Skid control ECU) | Check for any signs of corrosion or loose connections |
| Improper installation of the rear speed sensor | Ensure that the rear speed sensor is properly installed |
Rear Speed Sensor RH/LH
The rear speed sensor RH/LH can cause a Toyota C1407 code. This sensor detects the vehicle’s speed and sends this information to the skid control ECU. If this sensor is not working correctly, it can cause the C1407 code. The best solution for this issue is to check and replace the sensor with a new one if it is faulty.
Speed Sensor Circuit
The speed sensor circuit is also a potential cause of the C1407 code. This circuit is responsible for providing power to the rear speed sensor. If this circuit is damaged, it can cause the C1407 code. The best solution is to check the wiring and connectors for any signs of damage.

Brake Actuator Assembly
The brake actuator assembly (Skid control ECU) is another potential cause of the C1407 code. This assembly controls the vehicle’s speed and ensures it is within the legal limits. If this assembly is damaged, it can cause the C1407 code. The best solution is to check for any signs of corrosion or loose connections.
Improper Installation of the Rear Speed Sensor
The improper installation of the rear speed sensor can also cause a Toyota C1407 code. If this sensor is not installed properly, it can cause the C1407 code. The best solution is to install the rear speed sensor properly.
Conclusion
Toyota C1407 Code indicates an open or short in the rear speed sensor RH circuit, which can cause various issues. Therefore, it is important to identify the source of the problem and address it accordingly. The multiple causes of this code are rear speed sensor RH/LH, speed sensor circuit, brake actuator assembly, and improper installation of the rear speed sensor. The solutions for these causes are to check and replace the sensor with a new one if necessary, check the wiring and connectors for any damage, check for any signs of corrosion or loose connections, and ensure that the rear speed sensor is properly installed.
