P2100 | Throttle Actuator Control Motor Circuit / Open |
P2101 | Throttle Actuator Control Motor Circuit Range/Performance |
P2102 | Throttle Actuator Control Motor Circuit Low |
P2103 | Throttle Actuator Control Motor Circuit High |
DESCRIPTION
The ECM opens and closes the throttle valve using a DC motor type actuator. With the throttle valve, the exhaust gas recirculation volume can be properly controlled by opening and closing the valve. Also, engine vibration and noise will be reduced by closing the valve when the engine is stopped.

WIRING DIAGRAM
CAUTION / NOTICE / HINT
When the ECM must be replaced, before replacing the ECM, perform the "Learning Values Save" function using the GTS. Then after installing a new ECM, perform all of the initialization and registration procedures for the "Learning Values Write" function by following the instructions shown on the GTS display.
Read freeze frame data using the GTS. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, and other data from the time the malfunction occurred.
PROCEDURE
PERFORM ACTIVE TEST USING GTS (DIESEL THROTTLE TARGET ANGLE)
Connect the GTS to the DLC3.
Turn the ignition switch to ON and turn the GTS on.
Enter the following menus: Powertrain / Engine and ECT / Active Test / Diesel Throttle Target Angle / Data List / Actual Throttle Position.
Powertrain > Engine and ECT > Active TestActive Test Display |

CHECK WHETHER DTC OUTPUT RECURS (DTC P2100, P2101, P2102 OR P2103)
Connect the GTS to the DLC3.
Turn the ignition switch to ON and turn the GTS on.
Clear the DTCs.
Powertrain > Engine and ECT > Clear DTCsTurn the ignition switch off and wait for 30 seconds or more.
Turn the ignition switch to ON and wait for 10 seconds or more.
Start the engine and wait for 30 seconds or more.
Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
Confirm that the DTC is not output again.
