What is the solution to the P2 1 19 fault code?

Pacific Auto Network should first check whether there is an open circuit problem in the throttle sensor. The P2 1 19 fault code indicates that the throttle service sensor is out of range. It may be caused by the fault of the throttle position sensor, or it may be caused by the short circuit of the related circuit of the sensor. Take the correct solution according to the specific fault.

Check the throttle sensor for open circuit in time. The P2 1 19 fault code indicates that the throttle service sensor is out of range. It may be the fault of the throttle position sensor or the short circuit of the related circuit of the sensor.

The P2 1 19 fault code is applicable to all automobile manufacturers, which means that the throttle actuator controls the throttle body range/performance. After the ignition switch is turned off, the electronic throttle stays at the initial angle 14.5 degrees. This fault code may be recorded if the throttle valve is still closed after the ignition switch is turned off. It may be accompanied by problems such as difficulty in starting the engine.

In the Electronic Throttle Control (ETC) system, the function of the accelerator pedal position (APP) sensor is to transmit the position of the accelerator pedal to the throttle control module in the form of an electrical signal, which serves as a reference for the throttle actuator to control the throttle opening. The throttle actuator is a stepping motor, which is responsible for controlling the throttle opening according to the instruction of the throttle control module. The fault causes include the failure of the throttle return spring, the stuck throttle body and the failure of the electronic control module (PCM or ECM).
