The Toyota Code C1416 is a rear speed sensor LH output malfunction. This code is typically triggered by a malfunction in the rear speed sensor RH/LH, the speed sensor circuit, the speed sensor rotor, or the sensor installation. This code is a cause for concern, as it can lead to unresolved driving hazards. Fortunately, several solutions are available to help diagnose and fix the problem. These solutions include checking the rear speed sensor RH/LH, inspecting the speed sensor circuit, removing and reinstalling the speed sensor rotor, checking the sensor installation, and replacing the brake actuator assembly (skid control ECU). With these solutions, one can be sure their Toyota vehicle is running at optimal performance and safe to drive.

Inspecting the Speed Sensor Circuit
The speed sensor circuit should be inspected after checking the rear speed sensor RH/LH. This can be done by disconnecting the course and testing the voltage with a multimeter. If the voltage is incorrect, the sensor may need to be replaced or repaired.
Removing and Reinstalling the Speed Sensor Rotor
Another possible solution for Toyota Code C1416 is to remove and reinstall the speed sensor rotor. This is done by accessing the sensor rotor from the back of the vehicle and removing it. Then, the sensor should be reinstalled and tested to ensure it functions correctly.
Checking the Sensor Installation
If the sensor is installed incorrectly, it can cause the Toyota Code C1416. To check the installation, the sensor should be inspected to ensure it is properly mounted, connected, and sealed. If any of these components are incorrect, the sensor may need to be adjusted or replaced.
