2. REPLACE ECM
(a) Replace the ECM (for 2GR-FE) See: Powertrain Management/Computers and Control Systems/Engine Control Module/Service and
Repair/Components.
NEXT -- Continue to next step.
3. CHECK DTC (RADAR CRUISE CONTROL SYSTEM)
(a) Clear the DTCs See: Cruise Control/Testing and Inspection/Reading and Clearing Diagnostic Trouble Codes/Dynamic Radar Cruise
Control System.
(b) Perform the following to make sure that the DTC detection conditions are met.
HINT
If the detection conditions are not met, the malfunction cannot be detected.
(1) Drive the vehicle at a speed of 50 km/h (31 mph) or more.
(2) Turn the cruise control main switch on.
(c) Check for DTCs See: Cruise Control/Testing and Inspection/Reading and Clearing Diagnostic Trouble Codes/Dynamic Radar Cruise
Control System.

2GR-FE ENGINE CONTROL: SFI SYSTEM: P2102,P2103: Throttle Actuator Control Motor Circuit Low
DESCRIPTION
The throttle actuator is operated by the ECM and opens and closes the throttle valve using gears.
The opening angle of the throttle valve is detected by the throttle position sensor, which is mounted on the throttle with motor body assembly. The
throttle position sensor provides feedback to the ECM. This feedback allows the ECM to appropriately control the throttle actuator and monitor the
throttle opening angle as the ECM responds to driver inputs.
HINT
This electronic throttle control system does not use a throttle cable.
MONITOR DESCRIPTION
The ECM monitors the electrical current through the electronic actuator, and detects malfunctions and open circuits in the throttle actuator based on
this value. If the current is outside the standard range, the ECM determines that there is a malfunction in the throttle actuator. In addition, if the
throttle valve does not function properly (for example, stuck on), the ECM determines that there is a malfunction. The ECM then illuminates the
