*1: Accelerator pedal position sensor 2 signal and throttle position sensor 2 signal are converted by ECM internally. Thus, they differfrom
ECM terminals voltage signal.
*2: Indicates the intake manifold runner control valve.
*3: Before measuring the terminal voltage, confirm that the battery is fully charged. Refer to
PG-124, "EXCEPT FOR R9M : Work Proce-
.
*4: Varies with the atmospheric pressure changed by whether or elevation as this is an absolute pressure sensor.
