Q: What does code P1246 mean?

Accelerator Position Sensor 1 Circuit Malfunction. P1246 on Honda vehicles means the powertrain control module (PCM) has detected an abnormal signal from the accelerator pedal position (APP) sensor 1 circuit. The PCM compares APP sensor 1 against APP sensor 2 and expects a specific voltage relationship; when sensor 1's signal falls outside the expected range or disagrees with sensor 2, this code is stored and the vehicle may enter a reduced-power limp mode.
