P2118 Ford Throttle Actuator Control Motor Current Range/Performance
Possible causes
– Faulty Throttle Actuator Control Actuator
– Electronic Throttle Control System (ETCS) harness is open or shorted
– Electronic Throttle Control System (ETCS) circuit poor electrical connection
– Electronic Throttle Control System (ETCS) harness is open or shorted
– Electronic Throttle Control System (ETCS) circuit poor electrical connection
What about the obd code?
The Engine Control Module (ECM) monitors the battery supply voltage applied to the electronic throttle actuator. When the power supply voltage drops below the threshold, the ECM concludes that the power supply circuit has an open circuit. A DTC is set and the MIL is turned on.
Symptoms
– Engine Light ON (or Service Engine Soon Warning Light)
P2118 Ford Description
The Electronic Throttle Control System (ETCS) has a dedicated power supply circuit. The voltage (+BM) is monitored and when the voltage is low (less than 4 V), the Engine Control Module (ECM) 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. For this reason, when the voltage is low, the current to the actuator is cut. If repairs are made and the system has returned to normal, turn the ignition switch OFF. The ECM then allows current to flow to the actuator and actuator can be restarted.
