Loosen and retighten engine ground screws. Refer to
.
OK or NG
OK
>> GO TO 2.
NG
>> Repair or replace ground connections.
2.
CHECK APP SENSOR 2 POWER SUPPLY CIRCUIT
1.
Disconnect accelerator pedal position (APP) sensor harness
connector.
2.
Turn ignition switch ON.
3.
Check voltage between APP sensor terminal 1 and ground with
CONSULT-II or tester.
OK or NG
OK
>> GO TO 4.
NG
>> GO TO 3.
3.
DETECT MALFUNCTIONING PART
Check the following.
●
Harness connectors M77, F109
●
Harness for open or short between ECM and APP sensor
>> Repair open circuit or short to ground or short to power in harness or connectors.
4.
CHECK APP SENSOR
Refer to
EC-259, "Component Inspection"
.
OK or NG
OK
>> GO TO 5.
NG
>> Replace accelerator pedal assembly.

ACCELERATOR PEDAL POSITION SENSOR
1.
Reconnect all harness connectors disconnected.
2.
Turn ignition switch ON.
3.
Check voltage between ECM terminals 83 (APP sensor 1 sig-
nal), 91 (APP sensor 2 signal) and engine body under the fol-
lowing conditions.
4.
If NG, replace accelerator pedal assembly.

ECM Terminals and Reference valve
EBS013QD
Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
On Board Diagnosis Logic
EBS013QE
This self-diagnosis has the one trip detection logic.
The MI will not light up for this self-diagnosis.
DTC Confirmation Procedure
EBS013QF
NOTE:
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
WITH CONSULT-II
1.
Turn ignition switch ON and then turn OFF.
2.
Wait at least 30 seconds.
3.
Turn ignition switch ON.
4.
Select “DATA MONITOR” mode with CONSULT-II.
5.
If DTC is detected, go to
EC-263, "Diagnostic Procedure"
