Pedal value sensor, ME-SFI fault code description - AD07.61-P-4000-45L
| 1 | Fault code | P20CF Voltage difference between signal 1 and signal 2 (P0120) |
| ( |
P20DC Interruption at signal path 1 (P0120) P20DD Short circuit at signal path 1 (P0120) P20DE Interruption at signal path 2 (P0120) P20DF Short circuit at signal path 2 (P0120) P20E3 Voltage supply to accelerator pedal sensor (P0120) |

| 2 | Fault storage | After expiry of test duration and fault |
| Activation of the engine diagnosis indicator lamp (EURO3/4) or CHECK ENGINE (MIL) malfunction indicator lamp |
Following two successive driving cycles with faults | |
| 3 | Checking frequency | Continuous |
| 4 | Checked signal or status | Voltages at accelerator pedal sensor |
| 5 | Fault setting conditions | |
| Voltage difference between signal 1 and signal 2 | The signals may deviate from one another in the idle speed position no more than 8 %. For comparison purposes, signal 2 is multiplied by 2. | |
| Short circuit to positive | If signal 1 is larger than 4.9 V or signal 2 larger than 2.4 V, a short-circuit to positive is present (12 V or 5 V) or the accelerator pedal sensor is faulty. | |
| Short circuit to ground/open circuit | If signal 1 is smaller than 0.2 V or signal 2 smaller than 0.1 V, the cause is a short to ground, an interruption or the accelerator pedal sensor is faulty. | |
| Voltage supply | The voltage supply to the accelerator pedal sensor must lie between 4.75 to 5.25 V. | |
| 6 | Check prerequisites | Ignition ON |
| 7 | In the event of a fault, emergency mode is activated. |
