P2103 OBD-II: Throttle Actuator "A" Control Motor Circuit High
P2103 Severity
Should you fix P2103 yourself?
Identifying an OBD code is just the start of a complete diagnostic routine. Most trouble codes are caused by a sensor reporting a value that is out of range. Just replacing a sensor may not fix underlying issues. Be sure to understand the code, the part or system in your car that the code refers to, and the risks of delaying professional repair.
Proper diagnosis will save you time and money on unnecessary repairs.
Urgent codes indicate immediate action is necessary. These are urgent and significant malfunctions that can cause severe damage to the vehicle or harm the driver and passengers.
What causes OBD-II fault code P2103?
The throttle motor opens and closes the throttle plate, allowing more or less air to flow through the engine based on the driver's request for power. The throttle motor is controlled by the engine computer (PCM). If the PCM does not see the requested movement from the throttle motor, code P2103 will set. The PCM may also put the engine into "limp home mode", limiting the available power from the engine to prevent unwanted acceleration.
