Throttle Position (TP) Sensor

•
The TP sensor is built into the throttle body and detects the throttle valve opening angle.
•
The TP sensor uses Hall elements to detect throttle valve movement. This non-contact
sensor type improves durability.
•
The TP sensor is composed of a main sensor and a sub sensor, and detects the throttle
valve opening angle with these two sensors (main and sub).
•
Even if a malfunction occurs in either one of the sensors, the detection is performed and
drive-by-wire control is maintained.
•
If both the main and the sub sensor for the TP sensor fail, the signals necessary for the
drive-by-wire control are not input to the PCM and the drive-by-wire control is disabled.
•
However, even though the drive-by-wire control is disabled, the throttle valve opening
angle necessary for minimum driving is maintained mechanically.
