*: Accelerator pedal position sensor 2 signal and throttle position sensor 2 signal are converted by ECM internally. Thus, they differ from
ECM terminals voltage signal.
TERMINAL LAYOUT
PHYSICAL VALUES
NOTE:
• ECM is located behind the passenger side instrument lower panel. For this inspection, remove passenger
side instrument lower panel.
• Specification data are reference values and are measured between each terminal and ground.
• Pulse signal is measured by CONSULT-III.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECMs transistor. Use a ground other than ECM terminals, such as the ground.
