What does P0068 Throttle Angle Deviation mean?

[EmmettDella]

Fault code P0068 indicates a throttle angle deviation, which means there is a discrepancy between the angle of the throttle plate controlled by the ECU and the value monitored by the angle sensor. The engine control unit will report an intake manifold throttle angle deviation fault. The causes of throttle angle deviation fault include the following: 1. Intake boost sensor failure: Short circuit or open circuit in the sensor wiring. 2. Throttle solenoid valve failure: Due to prolonged use, aging wiring combined with high current load can easily cause an open circuit in the solenoid valve wiring, preventing the throttle from opening or closing. 3. Lack of timely vehicle maintenance: Accumulated dust and debris in the air filter can obstruct air intake into the engine, leading to abnormal boost pressure.
