P0123 2010 Ford Fusion Code - Throttle/Pedal Position Sensor 'A' Circuit High
Quick Answer
The throttle position (TP) sensor circuit is monitored by the Powertrain Control Module (PCM) for a high TP rotation angle (or voltage) input through the comprehensive component monitor (CCM). Common causes include Dirty throttle plate, Faulty throttle position sensor, Throttle position sensor harness is open or shorted. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
