Throttle Position Sensor/Switch A Circuit Malfunction

The throttle pedal sensor isn't communicating properly with the engine computer, either due to a bad sensor, wiring problem, or connector issue. This sensor tells the engine how much fuel you're requesting when you press the gas pedal. Without a proper signal, the engine may stall, hesitate, or run erratically.
