4. Loosen the accelerator pedal position sensor mounting
bolts, and then rotate it fully anticlockwise.
5. Check that the accelerator pedal position switch is on
(there should be continuity between terminals).
6. Slowly rotate the accelerator pedal position sensor
clockwise, and find the pint where the accelerator pedal
position switch is turned off (there will be no continuity).
At this point, tighten the accelerator pedal position sensor
mounting bolts securely.
7. Check output voltage of the accelerator pedal position
sensor (1st and 2nd channels).
Standard value: 0.4 – 0.9 V
8. If not within the standard value, check the accelerator
pedal position sensor (1st and 2nd channels) and its related
wiring harness.
FUEL PRESSURE TEST
MEASUREMENT OF FUEL LOW PRESSURE BETWEEN
FUEL PUMP (LOW PRESSURE) AND FUEL PUMP
(HIGH PRESSURE)
1. Release residual pressure from the fuel pipe line to prevent
fuel gush out. (Refer to P.13A-102.)
2. Disconnect the high-pressure fuel hose at the fuel pump
(high pressure) side.
Caution
Cover the hose connection with rags to prevent splash
of fuel that could be caused by some residual pressure
in the fuel pipe line.
