DTC P2111 Throttle Actuator Control System - Stuck Open
DTC P2112 Throttle Actuator Control System - Stuck Closed
DESCRIPTION
The throttle actuator is operated by the ECM, and opens and closes the throttle valve using the gears.
The opening angle of the throttle valve is detected by the Throttle Position (TP) sensor, which is mounted on the throttle body. The TP sensor provides feedback to the ECM so that it can control the throttle actuator and the throttle valve appropriately in response to driver inputs.
HINT: This ETCS (Electronic Throttle Control System) does not use a throttle cable.
MONITOR DESCRIPTION
The ECM determines that there is a malfunction in the ETCS when the throttle valve remains at the fixed angle despite a high drive current from the ECM. The ECM illuminates the MIL and sets a DTC.
If the malfunction is not repaired successfully, a DTC is set when the accelerator pedal is fully depressed and released quickly (to fully open and close the throttle valve) after the engine is next started.
MONITOR STRATEGY
TYPICAL ENABLING CONDITIONS
All:
P2111 (Throttle actuator stuck open):
P2112 (Throttle actuator stuck closed):
*: System guard set when following conditions met
TYPICAL MALFUNCTION THRESHOLDS
P2111 (Throttle actuator stuck open):
P2112 (Throttle actuator stuck closed):
FAIL-SAFE
When either of these DTCs, 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.
WIRING DIAGRAM
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 P2111 OR P2112)
Result
HINT: If any DTCs other than P2111 or P2112 are output, troubleshoot those DTCs first.
2 INSPECT THROTTLE BODY (VISUALLY CHECK THROTTLE VALVE)
OK: Throttle valve is not contaminated with foreign objects and moves smoothly.
3 CHECK WHETHER DTC OUTPUT RECURS (DTC P2111 OR P2112)
Result
CHECK FOR INTERMITTENT PROBLEMS
