2. Throttle Position Sensor Technical Specifications

As one of the system security measures, the system consists of dual output throttle position
sensors. One throttle position sensor output voltage signal increases as the throttle body opening
increases, while the other throttle position sensor output voltage signal decreases as the throttle
body opening increases.

Resistance value Between Terminals A and D: 1.9 ± 0.9 kΩ

FE02-5234b

Notes:

An oscilloscope can be used for detecting the above TPS sensor output signal, and the output
waveform line should be smooth without noise wave! If the output signal zeros or drops
suddenly when throttle body rotates at a certain angel, the ETC assembly shall be replaced.
ETC is an assembly. Do not disassemble it to repair.

2.2.7.13 Acceleration Pedal Position Sensor (APP) Inspection

As one of the system security measures, acceleration pedal position sensor is designed to have
dual outputs. Two sensors output voltage signals increase as the acceleration pedal position
increases.
