Throttle Actuator Control Throttle Body Range / Performance
DESCRIPTION
DTC
NO.
DTC DETECTION CONDITION
TROUBLE AREA
P2119
Throttle valve opening angle continues to vary greatly from target
opening angle (1 trip detection logic)
ETCS
ECM
Wire harness or
connector
MONITOR DESCRIPTION
values is outside the standard range, the ECM interprets this as a malfunction in the ETCS. The ECM then
illuminates the MIL and stores the DTC.
If the malfunction is not repaired successfully, the DTC is stored when the accelerator pedal is quickly released
(to close the throttle valve) after the engine speed reaches 5000 rpm by the accelerator pedal being fully
depressed (fully open the throttle valve).

CONFIRMATION DRIVING PATTERN
Connect the Techstream to the DLC3.
1.
Turn the ignition switch to ON and turn the Techstream on.
2.
Clear DTCs (even if no DTCs are stored, perform the clear DTC operation).
3.
Turn the ignition switch off and wait for at least 30 seconds.
4.
Turn the ignition switch to ON and turn the Techstream on [A].
5.
Start the engine.
6.
Idle the engine for 20 seconds.
7.
Enter the following menus: Powertrain / Engine and ECT / Trouble Codes [B].
8.
1UR-FE ENGINE CONTROL SYSTEM: SFI SYSTEM: P2119; Throttl...
Read the pending DTCs.
HINT:
If a pending DTC is output, the system is malfunctioning.
If a pending DTC is not output, perform the following procedure.
9.
Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.
10.
Input the DTC: P2119.
11.
Check the DTC judgment result.
TECHSTREAM
DISPLAY
DESCRIPTION
NORMAL
DTC judgment completed
System normal
ABNORMAL

System abnormal
INCOMPLETE
DTC judgment not completed
Perform driving pattern after confirming DTC enabling conditions
N/A
Unable to perform DTC judgment
HINT:
If the judgment result shows NORMAL, the system is normal.
If the judgment result shows ABNORMAL, the system has a malfunction.
If the judgment result shows INCOMPLETE or N/A, fully depress and release the accelerator
pedal 3 times, and then check the DTC judgment result [C].
12.
If no pending DTC is output, perform a universal trip and check for permanent DTCs
.
HINT:
If a permanent DTC is output, the system is malfunctioning.
If no permanent DTC is output, the system is normal.
13.
FAIL-SAFE
When this DTC 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 7° 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
opening angle 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.
Fail-safe mode continues until a pass condition is detected, and the ignition switch is then turned off.
