Step
Check
Yes
No
1
CHECK ACCELERATOR PEDAL POSITION
SENSOR OUTPUT.
1) Turn the ignition switch to ON.
2) Measure the voltage between ECM and
chassis ground.
Connector & terminal
Main accelerator pedal position sensor
signal
(B135) No. 23 (+) — Chassis ground (–):
Sub accelerator pedal position sensor
signal
(B135) No. 31 (+) — Chassis ground (–):
Is the difference in measured
values for the main accelerator
pedal position sensor signal
and the sub accelerator pedal
position sensor signal 0 V?
Go to step

CHECK ACCELERATOR PEDAL POSITION
SENSOR OUTPUT.
1) Measure the voltage between accelerator
pedal position sensor connector and chassis
ground.
Connector & terminal
(B315) No. 6 (+) — Chassis ground (–):
(B315) No. 3 (+) — Chassis ground (–):
Is the difference in measured
values for the main accelerator
pedal position sensor signal
and the sub accelerator pedal
position sensor signal 0 V?
Replace the accel-
erator pedal. <Ref.
to SP(H4SO)-4,
Accelerator
Pedal.>
Repair the harness
and connector.
NOTE:
In this case, repair
the following item:
• Open circuit in
harness between
ECM and acceler-
ator pedal position
sensor connector
• Short circuit to
ground in harness
between ECM and
accelerator pedal
position sensor
connector
• Poor contact of
coupling connector
3
CHECK HARNESS BETWEEN ECM AND AC-
CELERATOR PEDAL POSITION SENSOR
CONNECTOR.
Measure the resistance of harness between
accelerator pedal position sensor connector
and chassis ground.
Connector & terminal
(B315) No. 5 — Chassis ground:
(B315) No. 2 — Chassis ground:
Is the resistance less than 5
:
? Repair the poor
contact of ECM
connector.
Repair the harness
and connector.
NOTE:
In this case, repair
the following item:
• Open circuit in
harness between
ECM and acceler-
ator pedal position
sensor connector
• Open circuit of
harness between
ECM and engine
ground
• Poor contact of
ECM connector
• Poor contact of
coupling connector
