What is the TP sensor of Accord?

The signal voltage of the throttle position sensor increases with the increase of throttle opening. When the throttle valve is fully opened, its signal voltage is close to 5 V; When the throttle is closed (idling), the signal voltage is about 0.5V.

When the engine is running, the throttle position sensor is unplugged, and the harness plug of the electronic throttle control actuator or ECU is unplugged, it is necessary to perform the learning procedure of the throttle closed position. The essence of this learning program is to make ECU learn the position when the throttle valve is completely closed by detecting the output signal of the throttle position sensor.

Precautions:

Unstable idle speed when the engine is running, intermittent jitter when accelerating, slow response, high and low speed, and occasional short circuit or open circuit are also caused by the fault of the throttle body position sensor.

Improper installation and adjustment of the throttle body position sensor leads to the switch not being closed when the throttle body is fully closed, or the idle switch is still closed when the throttle body has a certain opening.

The sliding contact of linear variable resistor is poor, and the output signal of throttle body position sensor is interrupted intermittently during the process of throttle body from full close to full open.
