1 | Fault code | |
2 | Fault memory and actuation of CHECK ENGINE (MIL) | After two consecutive journeys with fault |
3 | Frequency of testing | Continuous |
4 | Checked signal or status | Comparison of voltage signals of set value potentiometers 1 and 2 |
5 | Difference at idle Difference at wide open throttle Plausibility Duration of test | < 8% < 25% Comparison of voltage signals of set value potentiometers 1 and 2 for air mass < 1 s |
6 | | To compare, multiply the voltage signal of set value potentiometer 2 by 2, because the supply voltage is only 2.5 V instead of 5.0 V. Up to approx. 10 % angle of rotation at the potentiometer is defined as idle, and wide open throttle from approx. 55 % angle of rotation. A brief high resistance at the closed throttle position stop is permissible. |
