DTC P2119 Throttle Actuator Control Throttle Body Range / Performance |
DESCRIPTION
The Electronic Throttle Control System (ETCS) is composed of the throttle actuator, throttle position sensor, accelerator pedal position sensor and ECM. The ECM operates the throttle actuator to regulate the throttle valve in response to driver inputs. The throttle position sensor detects the opening angle of the throttle valve and provides the ECM with feedback so that the throttle valve can be appropriately controlled by the ECM.| DTC No. | DTC Detection Condition | Trouble Area |
| P2119 | The throttle valve opening angle continues to vary greatly from the target opening angle (1 trip detection logic). |
|
FAIL-SAFE
When this DTC as well as other DTCs relating to ETCS (Electronic Throttle Control System) malfunctions are stored, the ECM enters fail-safe mode. During fail-safe mode, the ECM cuts the current to the throttle actuator and the throttle valve is returned to a 6.5° opening angle by the return spring. The ECM then adjusts the engine output by controlling the fuel injection (intermittent fuel-cut) and ignition timing in accordance with the accelerator pedal position to allow the vehicle to continue at a minimal speed. If the accelerator pedal is depressed firmly and gently, the vehicle can be driven slowly. The ECM continues operating in fail-safe mode until a pass condition is detected and the ignition switch is turned off.WIRING DIAGRAM
Refer to DTC P2102 (HILUX_TGN26 RM000000PFU0MIX_07.html).INSPECTION PROCEDURE
- HINT:
- Read freeze frame data using the intelligent tester. 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, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
| 1.CHECK FOR ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P2119) |
Connect the intelligent tester to the DLC3.
Turn the ignition switch to ON.
Turn the intelligent tester on.
Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
Read DTCs.
Result Result Proceed to P2119 is output A P2119 and other DTCs are output B - HINT:
- If any DTCs other than P2119 are output, troubleshoot those DTCs first.

| 2.READ VALUE USING INTELLIGENT TESTER (THROTTLE POSITION) |
Connect the intelligent tester to the DLC3.
Turn the ignition switch to ON.
Turn the intelligent tester on.
Clear DTCs (HILUX_TGN26 RM000000PDK0T7X.html).
Turn the ignition switch off and wait for at least 30 seconds.
Turn the ignition switch to ON.
Enter the following menus: Powertrain / Engine and ECT / Data List / All Data / Throttle Position No. 1 and Throttle Position Command.
Check the values displayed on the intelligent tester while fully depressing and releasing the accelerator pedal quickly.
Result Result Proceed to Throttle Position No. 1 does not change A Throttle Position No. 1 changes even a little B - HINT:
- When a DTC is output, the system changes to fail-safe mode. Therefore, only use the data up until the time the DTC is stored for confirmation.

| 3.INSPECT THROTTLE BODY WITH MOTOR ASSEMBLY (RESISTANCE OF THROTTLE ACTUATOR) |
Inspect the throttle body with motor assembly (HILUX_TGN26 RM000000VWM01WX.html).
|
| ||||
| OK | |
| 4.INSPECT THROTTLE BODY WITH MOTOR ASSEMBLY (VISUALLY CHECK THROTTLE VALVE) |
Check for contamination between the throttle valve and housing. If necessary, clean the throttle body. Also, check that the throttle valve moves smoothly.
- OK:
- Throttle valve is not contaminated with foreign objects and moves smoothly.
|
| ||||
| OK | |
| 5.READ VALUE USING INTELLIGENT TESTER (THROTTLE POSITION) |
Connect the intelligent tester to the DLC3.
Turn the ignition switch to ON.
Turn the intelligent tester on.
Clear DTCs (HILUX_TGN26 RM000000PDK0T7X.html).
Turn the ignition switch off and wait for at least 30 seconds.
Turn the ignition switch to ON.
Enter the following menus: Powertrain / Engine and ECT / Data List / All Data / Throttle Position No. 1, Throttle Position No. 2 and Throttle Position Command.
Check the values displayed on the intelligent tester while wiggling the ECM wire harness.
Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
Check for DTCs.
| Result | Proceed to |
| Value in Data List changes when wire harness is wiggled, or DTC is output* | A |

| 6.REPLACE THROTTLE BODY WITH MOTOR ASSEMBLY |
Replace the throttle body with motor assembly (HILUX_TGN26 RM000000VWO01YX.html).
| NEXT | |
| 7.CHECK WHETHER DTC OUTPUT RECURS (DTC P2119) |
Connect the intelligent tester to the DLC3.
Turn the ignition switch to ON.
Turn the intelligent tester on.
Clear DTCs (HILUX_TGN26 RM000000PDK0T7X.html).
Allow the engine to idle for 15 seconds or more.
Fully depress and release the accelerator pedal several times quickly.
Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
Read DTCs.
Result Result Proceed to No DTC is output A P2119 is output B
