DTC P2101 ELECTRIC THROTTLE CONTROL FUNCTION
PFP:16119
Description
NBS000W0
NOTE:
If DTC P2101 is displayed with DTC P2100 or 2119, first perform the trouble diagnosis for DTC P2100
or P2119. Refer to
EC-573, "DTC P2100, P2103 THROTTLE CONTROL MOTOR RELAY"
"DTC P2119 ELECTRIC THROTTLE CONTROL ACTUATOR"
.
Electric throttle control actuator consists of throttle control motor, throttle position sensor, etc.
The throttle control motor is operated by the ECM and it opens and closes the throttle valve.
The current opening angle of the throttle valve is detected by the throttle position sensor and it provides feed-
back to the ECM to control the throttle control motor to make the throttle valve opening angle properly in
response to driving condition.
On Board Diagnosis Logic
NBS000W1
This self-diagnosis has the one trip detection logic.
FAIL-SAFE MODE
When the malfunction is detected, ECM enters fail-safe mode and the MIL lights up.
DTC Confirmation Procedure
NBS000W2
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.
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 11V when engine
is running.
WITH CONSULT-II
1.
Turn ignition switch ON and wait at least 2 seconds.
2.
Select “DATA MONITOR” mode with CONSULT-II.
3.
Start engine and let it idle for 5 seconds.
4.
EC-581, "Diagnostic Procedure"
.
WITH GST
Follow the procedure “WITH CONSULT-II” above.
DTC No.
