The etcs (electronic throttle control system) has a dedicated power supply circuit. The throttle control motor relay is ON/OFF controlled by the ECM. ETC MOT PWR-B1 (Throttle actuator ″A″ control motor circuit/ open) ECM detects a voltage of power source for throttle control motor is excessively low. Electric throttle control actuator; FAIL-SAFE. The throttle actuator is operated by the Engine Control Module (ECM) and it opens and closes the throttle valve. The voltage (+BM) is monitored and when the voltage is low (less than 4 V), the Engine Control Module concludes that the ETCS has a fault and current to the throttle actuator is cut.When the voltage becomes unstable, the ETCS itself becomes unstable. 2). Throttle Actuator Control Motor Circuit Open (TACM) What the P2100 code means P2100 is an OBD-II generic code which indicates that the throttle actuator control motor (TACM) circuit is open, as detected by the Engine Control Module (ECM). Possible Causes For P1126: - Harness or connectors (Throttle control motor relay circuit is open) - Throttle control motor relay P0325 - Knock Sensor Circuit … ECM stops the electric throttle control actuator control, throttle valve is maintained at a fixed opening (approx. Power supply for the throttle control motor is provided to the ECM via the throttle control motor relay. Trouble Code: P2102. 1, No. P2101 is an OBD-II generic code for the engine control module (ECM) detecting the throttle actuator control (TAC) went out of the range of the circuit causing an open circuit to be detected in the TAC motor. If the P1126 Nissan code is stored, the Engine Control Module (ECM) shuts down the power for the throttle motor and the magnetic clutch, and the throttle valve is fully closed by the return spring. 16) to the throttle actuator control motor (terminals No. The voltage (+bm) is monitored and when it is low (less than 4 v), the ecm determines that there is a malfunction in the etcs and cuts off the current to the throttle actuator. 48re throttle valve actuator. When the ignition switch is turned ON, the ECM sends an ON signal to throttle control motor relay and battery … Power supply for the throttle control motor is provided to the ECM via the throttle control motor relay. Power supply for the throttle control motor is provided to the ECM via the throttle control motor relay. DTC Detection Conditions Trouble Areas P2118 Open in ETCS power source (+BM) circuit (1 trip detection logic) • Open in ETCS power source circuit e s u f S C T•E •ECM Related DTCs P2118: Throttle actuator motor power supply line range check (Low voltage)

The throttle actuator is operated by the Engine Control Module (ECM) and it opens and closes the throttle valve. When the ignition switch is turned OFF, the ECM sends an OFF signal to throttle control motor relay and battery voltage is not provided to the ECM. 16) to the throttle actuator control motor (terminals No. In this kind of system, the gas pedal acts as a sensor and sends a signal to the throttle actuator control motor, which then opens and closes the throttle … Vehicles with electronically controlled throttle bodies are equipped with a throttle actuator control motor, also known as drive-by-wire.

P2100 Description The throttle actuator is operated by the Engine Control Module (ECM) and it opens and closes the throttle valve.

What causes the P2101 code? The throttle actuator is operated by the Engine Control Module (ECM) and it opens and closes the throttle valve. 84) because of open circuit or short circuit …

… Harness or connectors (Throttle control motor circuit is open or shorted.) DTC P2100: Throttle Actuator Control Motor Circuit (open) CIRCUIT OPERATION Controls the current that is applied from the ECM (terminals No. The engine control module (ECM) signal returns from the TAC is an open circuit. Description. FordP2075 Ford DTC P2075 Make: Ford Code: P2075 Definition: Throttle Actuator Control Motor Circuit Malfunction (Open) Description: Key on or engine running; and the PCM detected an unexpected voltage condition on the Throttle Actuator Control Motor (TACM) circuit during the CCM test period. The opening angle of the throttle valve is detected by the throttle position sensor which is mounted on the throttle body. 1, No.

The actuator consists of a DC motor with a two-stage gear. P2118 Toyota Description The Electronic Throttle Control System (ETCS) has a dedicated power supply circuit.
