What causes the signal of the Jetta throttle pedal position sensor 2 to be too small?

[DominicMarie]

The signal of the Jetta's throttle pedal position sensor 2 is too small due to insufficient power supply, resulting in a weak signal. It is necessary to promptly inspect the vehicle's wiring to check for any short circuits or open circuits and carry out timely repairs. Below are the relevant details: 1. The throttle position sensor, also known as the throttle opening sensor, detects whether the engine is in an idle or composite working state. 2. When the throttle is in the idle position, the idle contact closes and sends an idle working state signal to the computer. When the throttle is in other positions, the idle contact opens, and the computer can identify the engine load through the signal from the throttle position sensor, thereby adjusting the engine's fuel injection volume. 3. There is a significant relationship between the vehicle's speed and the throttle. Regular cleaning of the throttle is required to avoid carbon buildup.
