Check the 'Possible Causes' listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector pins.
The cost to diagnose the P115F code is 1.0 hour of labor. The diagnosis time and labor rates at auto repair shops vary depending on the location, make and model of the vehicle, and even the engine type. Most auto repair shops charge between $75 and $150 per hour.
The Electromotive Throttle Actuator is attached to the intake plenum and adjusts the throttle valve. The air supply to the engine is modified by adjusting the throttle valve. The Digital Motor Electronics (DME) calculates the position of the throttle valve using the following information: Position of the accelerator pedal and Torque request from other control units.
The Digital Motor Electronics opens or closes the electromotive throttle actuator electrically. The throttle valve opening angle in the electromotive throttle actuator is monitored by 2 hall effect sensors. The throttle valve is moved by an electric actuator motor. This servomotor is actuated by a pulse-width modulated signal with a frequency of 1000 Hz.
The Digital Motor Electronics diagnosis monitors the voltages of both throttle valve sensors with respect to each other. The Diagnostic Trouble Code (DTC) is detected when the voltages of both throttle valve sensors deviate too far from each other.
