DTC Description
Fault cause
Probable trouble Area
25 P2101 - 16
Throttle
actuator
control motor circuit
range/performance,
indicates that the DLR
lies outside of the valid
control range - actuator
stuck
Circuit
voltage
below
threshold
1) Need to check if any obstruction for
actuating throttle valve.
2) Check if the wiring connections are
proper for the ETC.
3) If signals are fine at breakout box end,
then need to check with harness line or
else fault ETC.
4) Faulty ECU.

actuator
control system – idle
position not learned -
indicates that UMA-
learning was aborted
due to violated input
conditions
Signal stuck
high
1) Need to check if any obstruction for
actuating throttle valve.
2) Check if the wiring connections are
proper for the ETC.
3) If signals are fine at breakout box end,
then need to check with harness line or
else fault ETC.
4) Faulty ECU.
