3. Remove ground harness bolt (A) and ground harness from radi- ator core support.
4. Disconnect high-pressure pipe from expansion valve. Refer to HA-28, "
Exploded View".
CAUTION:
Cap or wrap the joint of the A/C piping and expan sion valve with suitable material such as vinyl
tape to avoid the entry of air.
5. Remove low-pressure flexible hose. Refer to HA-28, "
LOW-PRESSURE FLEXIBLE HOSE : Removal and
Installation".
6. Loosen flare nut from brake tubes using a flare nut wrench, then remove brake tubes from ABS actuator
and electric unit (control unit). Refer to BR-22, "
FRONT : Exploded View".
7. Disconnect the harness connector from the ABS actuator and electric unit (control unit).
8. Remove ABS actuator and electric unit (control unit) bracket bolts.
9. Remove the ABS actuator and electric uni t (control unit) and bracket as an assembly.
10. Remove bracket and bushing from ABS ac tuator and electric unit (if necessary).
INSTALLATION
Installation is in the reverse order of removal.
• Bleed the brake system. Refer to BR-13, "
Bleeding Brake System".
• Adjust the neutral position of steering angle sensor. Refer to BRC-55, "
ADJUSTMENT OF STEERING
ANGLE SENSOR NEUTRAL POSITION : Special Repair Requirement".
CAUTION:
• Replace the ABS actuator electric unit (control unit) if it has been dropped or sustained an impact.
• Do not install actuator by holding harness.

COMPONENT PARTS
Accelerator Pedal Position Sensor
INFOID:0000000012431271
The accelerator pedal position sensor is installed on the upper end
of the accelerator pedal assembly. The sensor detects the accelera-
tor position and sends a signal to the ECM.
Accelerator pedal position sensor has two sensors. These sensors
are a kind of potentiometer which transform the accelerator pedal
position into output voltage, and emit the voltage signals to the ECM.
The ECM judges the current opening angle of the accelerator pedal
from these signals and controls the throttle control motor based on
these signals.
Idle position of the accelerator pedal is determined by the ECM
receiving the signal from the accelerator pedal position sensor. The
ECM uses this signal for the engine operation such as fuel cut.
