ME-SFI pedal value sensor - Fault code description - AD07.61-P-4000-45A
| 1 | Fault code | P1542 |
| 2 | Fault storage | Fault is immediately stored |
| Activation of the engine diagnosis (EURO3/4) or CHECK ENGINE (MIL) malfunction indicator lamp |
No malfunction indicator lamp activation | |
| 3 | Frequency of the test | Continuously |
| 4 | Checked signal or status | Comparison of voltage signals 1 and 2 (from potentiometers or Hall sensors) |
| 5 | Fault setting conditions Voltage difference between signal 1 and signal 2 |
Fault if the voltage difference is greater than 8 % (up to approx. 60 % torque angle at the pedal value sensor) or greater than 25 % (as of 60 % torque angle). For comparison purposes, voltage signal 2 is multiplied by 2. |
| Duration of test | Approx. 30 s | |
| 6 | Test prerequisites |
|
| 7 | On commencement of engine 112, 113 production, a pedal value sensor with Hall sensors will be phased in. If faults are detected, a switch to limp-home mode is carried out. |
