DTC P2119 Throttle Actuator Control Throttle Body Range / Performance
DESCRIPTION
The Electronic Throttle Control System (ETCS) is composed of the throttle actuator, Throttle Position (TP) sensor, Accelerator Pedal Position (APP) sensor, and ECM. The ECM operates the throttle actuator to regulate the throttle valve in response to driver inputs. The TP 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.
MONITOR DESCRIPTION
The ECM determines the actual opening angle of the throttle valve from the TP sensor signal. The actual opening angle is compared to the target opening angle commanded by the ECM. If the difference between 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 sets the DTC.
If the malfunction is not repaired successfully, the DTC is set 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).

TYPICAL ENABLING CONDITIONS
TYPICAL MALFUNCTION THRESHOLDS
FAIL-SAFE When this DTC, as well as other DTCs relating to ETCS (Electronic Throttle Control System) malfunctions, is set, the ECM enters fail-safe mode. During fail-safe mode, the ECM cuts the current to the throttle actuator off, and the throttle valve is returned to a 6 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 slowly, the vehicle can be driven slowly.
Fail-safe mode continues until a pass condition is detected, and the ignition switch is then turned off.

Refer to DTC P2102.
INSPECTION PROCEDURE
HINT: 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)
Result
HINT: If any DTCs other than P2119 are output, troubleshoot those DTCs first
2 CHECK WHETHER DTC OUTPUT RECURS (DTC P2119)
CAUTION: Perform the procedures "A" and "B" below with great care. Failure to do so may result in the vehicle unexpectedly rolling away.
HINT: The voltage output of the throttle position sensor can be checked during procedure "B" using the intelligent tester.
Variations in the voltage output indicate that the throttle actuator is in operation. To check the voltage output using the intelligent tester, select the following menu items: DIAGNOSIS / ENHANCED OBD II / DATA LIST / PRIMARY / THROTTLE POS #1.
OK: No DTC output.
CHECK FOR INTERMITTENT PROBLEMS
Check mode procedure
HINT:
Check mode has a higher sensitivity to malfunctions and can
detect malfunction that normal mode cannot detect. Check
mode can also detect all the malfunctions that normal mode
can detect. In check mode, DTCs are detected with 1-trip
detection logic.
