TYPICAL ACCELERATOR PEDAL DIAGNOSTIC THRESHOLDS
| P2122
- Observed voltage on first pedal track <0.25V P2123 - Observed voltage on first pedal track >4.75V P2127 - Observed voltage on second pedal track <0.25V P2128 - Observed voltage on second pedal track > 4.75V P2138 - The absolute value of the difference between ((voltage on pedal track 1)/2 - voltage on pedal track 2) exceeds a threshold dependent on pedal track 2 voltage (0.25V @ pedal track 2 voltage of 1.2V, 0.5V @ pedal track 2 voltage of 1.96V) |
