DTC P2119 Throttle Actuator Control Throttle Body Range / Performance |
DESCRIPTION
The electronic throttle control system 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 | Throttle valve opening angle continues to vary greatly from target opening angle (1 trip detection logic) |
|
FAIL-SAFE
When either of these DTCs, or 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° throttle 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 then turned off.
WIRING DIAGRAM
Refer to DTC P2102 (Link).INSPECTION PROCEDURE
- HINT:
- Refer to "Data List / Active Test" [Throttle Position Command, Throttle Position No. 1, Throttle Motor Current, Throttle Motor Duty (Open), Throttle Motor Duty (Close)] (CAMRY_ACV40 RM000000PDN0GRX.html).
- Read freeze frame data using the intelligent tester. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can be helpful in determining whether the vehicle was running or stopped, whether the engine was warmed up or not, whether the air fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction.
| 1.CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P2119) |
Connect the intelligent tester to the DLC3.
Turn the ignition switch to ON.
Turn the tester on.
Enter the following menus: Powertrain / Engine and ECT / DTC.
Read the DTCs.
- Result:
Result Proceed to DTC P2119 is output A DTC 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 tester on.
Clear the DTCs (CAMRY_ACV40 RM000000PDK0LEX.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 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 WITH MOTOR BODY ASSEMBLY (RESISTANCE OF THROTTLE ACTUATOR) |
Inspect the throttle with motor body assembly (CAMRY_ACV40 RM0000012NC007X.html).
|
| ||||
| OK | |
| 4.INSPECT THROTTLE WITH MOTOR BODY 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 tester on.
Clear the DTCs (CAMRY_ACV40 RM000000PDK0LEX.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 tester while wiggling the ECM wire harness.
Enter the following menus: Powertrain / Engine and ECT / DTC.
Check for DTCs.
*: As the DTC was stored due to a change in the contact resistance of the connector, repair or replace the wire harness or connector (CAMRY_ACV40 RM000000UZ301ZX.html).Result Result Proceed to Value in Data List changes when wire harness is wiggled, or DTC is output* A Other than above B

| 6.REPLACE THROTTLE WITH MOTOR BODY ASSEMBLY |
Replace the throttle with motor body assembly (CAMRY_ACV40 RM0000017UD03XX.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 tester on.
Clear the DTCs (CAMRY_ACV40 RM000000PDK0LEX.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 / DTC.
Read the DTCs.
- Result:
Result Proceed to No DTC output A DTC P2119 is output B
