P2101 ELECTRIC THROTTLE CONTROL FUNCTION
P2101 ELECTRIC THROTTLE CONTROL FUNCTION
Description
INFOID:0000000000955032
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 Logic
INFOID:0000000001115104
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
.
Diagnosis Procedure
INFOID:0000000000955036
1.
CHECK GROUND CONNECTIONS
1.
Turn ignition switch OFF.
2.
Check ground connection E17. Refer to Ground inspection in
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 connector E7, F121
• 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.
4.
