THROTTLE POSITION (TP) SENSOR CONSTRUCTION/OPERATION [LF]
E5U014018910N02
• The sensor is built into the throttle body and
detects the throttle valve opening angle.
• The Hall element design has been adopted for the
sensor.
• A non contact type sensor has been adopted to
improve durability.
• The TP sensor is composed of the main sensor
and 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 with a normal
sensor and drive-by-wire control is maintained.
• If both the MAIN and SUB sensors for the TP
sensor malfunction, 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.
