CHECK FREEZE FRAME DATA
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON.
(c) Using the Techstream, check "ISC Learning Value" in the freeze frame data
.
HINT:
Be sure to confirm "ISC Learning Value" in the freeze frame data as it is used when confirming whether
the malfunction has been successfully repaired.

DTC CODE
DTC DETECTION CONDITION
TROUBLE AREA
P2111
Throttle actuator does not close when signaled by ECM
(1 trip detection logic)
Throttle actuator
Throttle body assembly
Throttle valve
Wire harness or connector
P2112
Throttle actuator does not open when signaled by ECM
(1 trip detection logic)
Throttle actuator
Throttle body assembly
Throttle valve
Wire harness or connector
MONITOR DESCRIPTION
The ECM determines that there is a malfunction in the ETCS when the throttle valve remains at a 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.
