Last Modified: 9-16-2014 6.6 C Doc ID: RM000000PFV11BX Model Year: 2015 Model: Tundra Prod Date Range: [08/2014 - ] Title: 1UR-FE ENGINE CONTROL SYSTEM: SFI SYSTEM: P2111,P2112; Throttle Actuator Control System - Stuck Open; 2015 MY Tundra [08/2014 - ] 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 gears. The opening (throttle valve) appropriately in response to driver inputs. HINT: This ETCS (Electronic Throttle Control System) does not use a throttle cable. DTC NO. DTC DETECTION CONDITION TROUBLE AREA P2111 Throttle actuator does not close when signaled by ECM (1 trip detection logic) Throttle actuator Throttle with motor body assembly Throttle valve ECM Wire harness or connector P2112 Throttle actuator does not open when signaled by ECM (1 trip detection logic) Throttle actuator Throttle with motor body assembly Throttle valve ECM 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 stores a DTC. If the malfunction is not repaired successfully, a DTC is stored when the accelerator pedal is fully depressed and released quickly (to fully open and close the throttle valve) after the engine is next started.
