DTC P2103 Throttle Actuator Control Motor Circuit High

CIRCUIT DESCRIPTION

DTC Detection Condition:

The throttle motor is operated by the ECM. It opens and closes the throttle valve.

The opening angle of the throttle valve is detected by the throttle position sensor which is mounted on the throttle body and it provides feedback to the ECM to control the throttle motor in order to the throttle valve opening angle properly in response to driving condition.

If this DTC is stored, the throttle valve is locked at a certain opening angle. Also, the whole electronically controlled throttle operation is cancelled until the system returns to normal and the ignition switch is turned OFF.

MONITOR DESCRIPTION

Monitor Strategy:

Typical Enabling Conditions:

Typical Malfunction Thresholds:

The ECM monitors the current flows through the electronic throttle motor and detects malfunctions or an open circuit in the throttle motor based on the current value. When the current deviates from standard range, the ECM concludes that there is a fault in the throttle motor ECM turns on MIL and a DTC is set.

Example:
The current is less than 0.5 A when the motor driving duty ratio is exceeding 80%. The ECM concludes that the current is out of range, turns on the MIL and a DTC is set.

INSPECTION PROCEDURE

Step 1 - 2:

Step 3 - 4:

HINT: Read freeze frame data using the hand-held tester or the OBD II scan tool. Freeze frame data records the engine conditions when a malfunction is detected. When troubleshooting, freeze frame data can help determine if the vehicle was running or stopped, if the engine was warmed up or not, if the air-fuel ratio was lean or rich, as well as other data from the time when a malfunction occurred.
