What does the P161F fault code mean?

[VonEmily]

P161F fault code indicates Throttle Valve Actuator 2 - Position Self-Test Fault. Here is an introduction to throttle-related content: 1. Function: The throttle's role is to control air entering the engine. After entering the intake pipe, the air mixes with gasoline to form a combustible mixture, which then burns to produce work. 2. Principle: The principle of the throttle is that in traditional engines, the throttle control mechanism operates via a cable (flexible steel wire) or rod, connecting the accelerator pedal at one end and the throttle linkage plate at the other. Electronic throttles mainly use throttle position sensors to control the throttle opening angle based on the engine's required energy, thereby regulating the amount of air intake.
