P2101 ELECTRIC THROTTLE CONTROL FUNCTION
P2101 ELECTRIC THROTTLE CONTROL FUNCTION
DescriptionINFOID:0000000001162663
By default the valve is open when in the rest position and is actuated only when the engine is switched off; this
has a damping effect and helps to stop the engine.
DTC LogicINFOID:0000000001162664
DTC DETECTION LOGIC
NOTE:
Conditions for applying the diagnostic procedure to the stored DTCs:
The DTC is declared present after the engine is started or following a load test.
Special note:
If DTC P2101 2.DEF is displayed, first perform trouble diagnosis for DTC P0120. Refer to EC-1134,
"DTC Logic".
Diagnosis ProcedureINFOID:0000000001162665
1.CHECK GROUND CONNECTIONS
1. Turn ignition switch OFF.
2. Check ground connection E15. Refer to Ground inspection in GI-58, "
Circuit Inspection".
Is the inspection result normal?
YES >> GO TO 2.
NO >> Repair or replace ground connection.
2.CHECK ELECTRIC THROTTLE CONTROL ACTUATOR POWER SUPPLY CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect electric throttle control actuator harness connector.
3. Turn ignition switch ON.
4. Check the voltage between electric throttle control actuator harness connector and ground.
Is the inspection result normal?
YES >> GO TO 4.
NO >> GO TO 3.
3.DETECT MALFUNCTIONING PART
Check the following.
 IPDM E/R
 Harness connectors E8, F8
 Harness for open or short between IPDM E/R and electric throttle control actuator
 Harness for open or short between ECM and electric throttle control actuator
>> Repair open circuit or short to ground or short to power in harness or connectors.

P2120 APP SENSOR
DescriptionINFOID:0000000001162667
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.

DTC DETECTION LOGIC
NOTE:
If DTC P2120 is displayed with DTC P0641, first perform trouble diagnosis for DTC P0641. Refer to
EC-1180, "
DTC Logic".
 Conditions for applying the diagnostic procedure to the stored DTCs:
- The DTC is declared present after a series of full load-no load accelerator pedal actions have been carried
out (engine stopped, ignition on).
If the DTC is present:
-Malfunction indicator (Red) lights up.
Diagnosis ProcedureINFOID:0000000001162669
1.CHECK GROUND CONNECTIONS
1. Turn ignition switch OFF.
2. Check ground connection E15. Refer to Ground inspection in GI-58, "
Circuit Inspection".
Is the inspection result normal?
YES >> GO TO 2.
NO >> Repair or replace ground connection.
2.CHECK ACCELERATOR PEDAL POSITION SENSOR POWER SUPPLY CIRCUIT
1. Disconnect accelerator pedal position sensor harness connector.
2. Turn ignition switch ON.
3. Check the voltage between accelerator pedal position sensor connector and ground.
Is the inspection result normal?
YES >> GO TO 4.
NO >> GO TO 3.
