KIA Jiahua Commercial Vehicle v6 Engine p0 120 Throttle Position

This fault code indicates that the accelerator pedal sensor and the accelerator position sensor are faulty.

I suggest you look at the data flow of the sensor first to see which sensor is the problem.

Then carry out maintenance, first check the wiring, and then check the sensor.

If you don't understand the car problem, ask the car master. You can ask directly!
