DTC P0652, P0653 SENSOR POWER SUPPLY
PFP:18002
Description
EBS0159H
The accelerator pedal position sensor is installed on the upper end
of the accelerator pedal assembly. The sensors detect the accelera-
tor pedal position and sends a signal to the ECM. The ECM uses the
signal to determine the amount of fuel to be injected.
CONSULT-II Reference Value in Data Monitor Mode
EBS0159I
Specification data are reference values.
*: This signal is converted by ECM internally. Thus, it differs from ECM terminal voltage.
ECM Terminals and Reference Value
EBS0159J
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.

DTC Confirmation Procedure
EBS0159L
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.
2.
Select “DATA MONITOR” mode with CONSULT-II.
3.
Wait at least 5 seconds.
4.
If DTC is detected, go to

APP sensor 2 is excessively low.
●
Harness or connectors
(The APP sensor 2 power supply cir-
cuit is open or shorted.)
●
Accelerator pedal position sensor
(Accelerator pedal position sensor 2)
P0653
Accelerator pedal position
sensor 2 power supply cir-
cuit high
ECM detects a voltage of power source for the
APP sensor 2 is excessively high.

1.
CHECK GROUND CONNECTIONS
1.
Turn ignition switch OFF.
2.
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-557, "Component Inspection"
.
OK or NG
OK
>> GO TO 5.
NG
>> Replace accelerator pedal assembly.
