P2105 Code: Throttle Actuator Control System – Forced Engine Shutdown
P2105 Code: Throttle Actuator Control System – Forced Engine ShutdownThe ETC system is composed of an APP sensor, an electronic throttle actuator (servomotor), a throttle position (TP) sensor, and a PCM. When the driver steps on the gas pedal, the APP sensor sends a signal to the TP sensor, which provides throttle angle feedback to the PCM.

What Is a Throttle Actuator? Function and Symptoms of Failure Explained
What Is a Throttle Actuator? Function and Symptoms of Failure ExplainedThe DC motor operates a set of gears that gives the motor tremendous torque. It both closes and opens the throttle plate, even though there’s a spring that holds the plate in its default (closed) position when the throttle body isn’t powered (engine off, key off).– Richard McCuistian, ASE Certified Master
