c) Measure output voltage variation while throttle
valve is opened and closed as following
specification.
If sensor voltage is out of specified value and linear
variation as the following graph, replace electric throttle
body assembly.
Throttle position sensor output voltage
Throttle position sensor (main) [A]: 0.45 – 4.88 V,
varying according to throttle valve opening by finger
(Voltage should vary by 0.04 V for each 1
°
valve
opening)
Throttle position sensor (sub) [B]: 1.33 – 5.007 V,
varying according to throttle valve opening by finger
(Voltage should vary by about 0.032 V for each 1
°
valve opening)
Electric Throttle Body System Calibration
S5JB0A1306023
NOTE
If the service described under the
“Precautions of Electric Throttle Body
System Calibration: in Section 1A” is
performed, calibrate electric throttle body
system as follows.
1) If electric throttle body assembly and/or accelerator
pedal position (APP) sensor assembly are replaced,
perform following steps.
a) Disconnect negative cable at battery for 20
seconds or more for the purpose of clearing
calibration data of closed throttle position from
memory in ECM.
b) Connect negative cable to battery.
2) Keep ignition switch at ON position for 5 seconds or
more without running engine.
[A]: For J20 engine
[B]: For M16 engine
