2 1 Teana dashboard shows a yellow triangle on the left rear wheel of a car. What does that mean?

2 1 Teana dashboard shows a yellow triangle on the left rear wheel of a car, indicating that the vehicle stability system is faulty. The vehicle stability system collects signals through sensors, and calculates the speed and steering angle of the vehicle at this time. If there is understeer when cornering, it will automatically control the braking of the side wheels and automatically adjust the throttle to correct the steering trajectory. Similarly, oversteer is also automatically adjusted to ensure driving safety.

The throttle actuator is stuck in the closed position, and the ECM sends an instruction to open the throttle, but the actuator is stuck in the closed position. If there is nothing wrong with the electronic throttle safety and the wiring harness, the needle angles of 1 and 2 are the throttle motor coils, and the resistance value is abnormal. Replace the throttle valve, and the electronic control system of the body stability system has failed. It is recommended to find a repair shop decoder to read the fault code before repair.

ESP system is composed of control unit and steering sensor, which monitors the steering angle of the steering wheel, wheel sensor monitors the rotating speed of each wheel, sideslip sensor monitors the state of the car body rotating around the vertical axis, and lateral acceleration sensor monitors the centrifugal force when the car turns.
