Toyota Code C1235/35 is an issue that affects the speed sensor signals in the vehicle. The code is triggered when noise in the speed sensor signals occurs more than 75 times in 5 seconds when the vehicle speed is more than 20 km/h (12 mph). This issue can occur for various reasons, such as the front speed sensor RH, speed sensor rotor, sensor installation, or the master cylinder solenoid (Skid control ECU). Additionally, the signal high time is greater than the maximum concerning time.

Causes and Solutions for Toyota Code C1235/35
| Cause | Solution |
|---|---|
| Front speed sensor RH | Replace the front speed sensor RH |
| Speed sensor rotor | Inspect and clean the speed sensor rotor |
| Sensor installation | Check the installation of the speed sensor |
| Master cylinder solenoid (Skid control ECU) | Replace the master cylinder solenoid |
Front Speed Sensor RH
The front speed sensor RH is an important part of the vehicle’s speed control system. It measures the car’s speed and transmits the data to the ECU. If the sensor is faulty, it can cause Toyota Code C1235/35 to be triggered. In such cases, replacing the front speed sensor RH is best to solve the issue.
Speed Sensor Rotor
The speed sensor rotor is another important component of the speed control system. It helps the ECU to measure the speed of the vehicle accurately. If the rotor is clogged or dirty, it can cause Toyota Code C1235/35 to be triggered. Therefore, inspecting and cleaning the speed sensor rotor regularly is important.

Sensor Installation
Installing the speed sensor is also important for the system’s proper functioning. Improper speed sensor installation can lead to Toyota Code C1235/35. Therefore, it is important to check the speed sensor installation regularly.
Master Cylinder Solenoid
The master cylinder solenoid is an important part of the Skid Control ECU. It helps the ECU to control the speed of the vehicle accurately. If the solenoid is faulty, it can lead to Toyota Code C1235/35. In such cases, it is best to replace the master cylinder solenoid to solve the issue.
Conclusion
Toyota Code C1235/35 is an issue that affects the speed sensor signals in the vehicle. It is important to identify the cause of the problem and take the necessary steps to resolve it. The causes of Toyota Code C1235/35 can be attributed to the front speed sensor RH, speed sensor rotor, sensor installation, or the master cylinder solenoid (Skid control ECU). The solutions for this issue include replacing the front speed sensor RH, inspecting and cleaning the speed sensor rotor, checking the installation of the speed sensor, and replacing the master cylinder solenoid. To avoid any issues related to Toyota Code C1235/35, it is important to maintain and regularly inspect the speed control system.
