DTC
P2119
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
Wire harness or
connector
ECM
MONITOR DESCRIPTION
these two 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.
Read the pending DTC.
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.

DESCRIPTION
NORMAL
DTC judgment completed
System normal
ABNORMAL
DTC judgment completed
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 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 is 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.
WIRING DIAGRAM
Refer to DTC P2102
.
INSPECTION PROCEDURE
HINT:
Read freeze frame data using the Techstream. 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.
PROCEDURE
1.
CHECK FOR ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P2119)
3UR-FBE ENGINE CONTROL SYSTEM: SFI SYSTEM: P2119; Thrott...
A
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON.
(c) Turn the Techstream on.
(d) Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
(e) 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.
B
GO TO DTC CHART
2.
READ VALUE USING TECHSTREAM (THROTTLE POSITION)
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON.
(c) Turn the Techstream on.
(d) Clear DTCs
.
(e) Turn the ignition switch off and wait for at least 30 seconds.
(f) Turn the ignition switch to ON.
(g) Enter the following menus: Powertrain / Engine and ECT / Data List / Throttle Position No. 1
and Throttle Position Command.
(h) Check the values displayed on the Techstream 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.
