CIRCUIT DESCRIPTION
HINT:
SThis Electrical Throttle Control System (ETCS) does not use a throttle cable.
SThis throttle position sensor uses 2 hall ICs.
The throttle position sensor is mounted on the throttle body and it detects the opening angle of the throttle
valve. This sensor is electronically controlled and uses Hall−effect elements, so that accurate control and
reliability can be obtained. The throttle position sensor has 2 sensor elements / 2 signal output: VTA1and
VTA2. VTA1used to detect the throttle opening angle and VTA2 is used to detect malfunctions in VTA1. Volt-
age applied to VTA1and VTA2 change between 0V and 5V in proportion to the opening angle of the throttle
valve. There are several checks that the ECM performs to confirm proper operation of the throttle position
sensor and VTA1.
The ECM judges the current opening angle of the throttle valve from these signals input from terminals VTA1
and VTA2, and the ECM controls the throttle motor to make the throttle valve angle properly in response to
driver inputs.

CIRCUIT DESCRIPTION
HINT:
SThis Electrical Throttle Control System (ETCS) does not use a throttle cable.
SThis accelerator pedal position sensor is a non−contact type.
The accelerator pedal position sensor is mounted on the accelerator pedal bracket. The accelerator pedal
position sensor has 2 sensor elements / signal output: VPA1and VPA2. VPA1is used to detect the actual
accelerator pedal angle (used for engine control) and VPA2 is used to detect malfunctions in VPA1. Voltage
change of VPA1and VPA2 change between 0V and 5V depending on the accelerator pedal angle.
The ECM monitors the accelerator pedal angle from VPA1and VPA2 signal output, and controls the throttle
motor based on these signals.

CURRENT RANGE/PERFORMANCE
CIRCUIT DESCRIPTION
The Electronic Throttle Control System (ETCS) has a dedicated power supply circuit. The voltage (+BM) is
monitored and when the voltage is low (less than 4V), the ECM concludes that the ETCS has a fault and
current to the throttle control motor is cut.
When the voltage becomes unstable, the ETCS itself becomes unstable. For this reason, when the voltage
is low, the current to the motor is cut. If repairs are made and the system has returned to normal, turn the
ignition switch to OFF. The ECM then allows current to flow to the motor and the motor can be restarted.
