Possible cause

P2100

THROTTLE ACTUATOR A
(Throttle actuator “A” control 
motor circuit/open)

• An excessively low voltage from the TP 

sensor is sent to ECM.

• An excessively high current from the TP 

sensor is sent to ECM.

• TP sensor becomes over temperature.

• Harness or connectors

(Electric throttle control motor circuit is 
open or shorted)

• Electric throttle control actuator

.

Is the inspection result normal?

YES

>> Check intermittent incident. Refer to 

GI-41, "Intermittent Incident"

.

NO

>> Replace electric throttle control actuator.

Component Inspection (Throttle Control Motor)

INFOID:0000000010379164

1.

CHECK THROTTLE CONTROL MOTOR

1.
