Code P1228 Infiniti Description
The P1228 Infiniti code indicates a problem with the Accelerator Pedal Position Sensor 2 Circuit, specifically detecting a high input signal. This sensor is responsible for monitoring the position of the accelerator pedal and sending this information to the Engine Control Module (ECM) to adjust the fuel injection and ignition timing. When the sensor detects a high input signal, it means that the voltage level being received is outside the normal range, which can lead to various performance issues in the vehicle.
Common Causes of P1228 Infiniti
- Faulty accelerator pedal position sensor
- Damaged wiring or connectors in the sensor circuit
- ECM malfunction
- Corrosion or water damage in the sensor components
- Electrical issues such as short circuits or open circuits
