Throttle motor position sensor 2, circuit fault.

The fault causes include the throttle motor position sensor itself or its circuit or connector failure, powertrain control module, etc. I hope my answer is useful to you.

Throttle, commonly known as throttle valve, is a controllable valve used to control the intake of engine. The position sensor of the throttle motor is used to transmit the throttle opening to the electronic control unit in the form of electrical signal, which is one of the basic parameters to control the fuel injection of the engine.
