P2 106 Fault Code Solution

The fault code P2 106 of Pacific Auto Network means that the throttle actuator control system (engine) is forced to limit its power. The fault causes include TACM circuit or connector fault, electronic control module (PCM or ECM) fault, etc. Need to bring professional tools to 4S for code reading and maintenance.

P2 106 fault code is applicable to all automobile manufacturers, which means that the throttle actuator control system (engine) is forced to limit its power. 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 electrical signals, which can be used 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. When operating in FMEM mode, this fault code will appear if the electronic control module detects that the throttle actuator control motor (TACM) system is in forced power limiting mode.
