Code P2109 2017 Toyota RAV4 Description

The idling speed is controlled by the Electronic Throttle Control System (ETCS). The ETCS is comprised of a throttle actuator, which operates the throttle valve, and a throttle position sensor, which detects the opening amount of the throttle valve. The Engine Control Module (ECM) controls the throttle actuator to adjust the throttle valve opening amount so that the idling speed is maintained at the target idling speed. The Diagnostic Trouble Code (DTC) will be set with the manifold absolute pressure sensor normal and atmospheric pressure 85 kPa (638 mmHg) or more (elevation 1400 m (4592 ft.) or less), when the engine coolant temperature is 45°C (113°F) or less at engine start, the engine is warmed up and conditions for Idle Speed Control (ISC) learning are met, the ISC learning value is approximately 3 times larger than normal even though the intake manifold pressure when idling is normal.
