| Fuel injectors (Y62y1 to Y62y6) | |||
|---|---|---|---|
| 1 | Fault code | P201D Cylinder 1 (Y62y1) (P0201) | |
| ( |
P2021 Cylinder 2 (Y62y2) (P0202) P201F Cylinder 3 (Y62y3) (P0203) P201E Cylinder 4 (Y62y4) (P0204) P2022 Cylinder 5 (Y62y5) (P0205) P2020 Cylinder 6 (Y62y6) (P0206) |

| 2 | Fault storage | after expiry of test duration and fault | |
| Actuation 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 | Current/voltage test on respective fuel injector | |
| 5 | Fault setting conditions | Voltage lower than 2, 5 volts | |
| Limit values | Current higher than 4, 2 amps | ||
| Short circuit to ground | No voltage on fuel injection valve | ||
| Short circuit to+12V | Approx. 4 to 8 V on under no load output of the ME control unit | ||
| Open circuit in wiring | approx. 1 seconds | ||
| Checking duration | |||
| 6 | Check prerequisites | Battery voltage between 8 and 17V | |
| 7 | The actuation of each fuel injector is tested for line interruption and short circuit (to ground or battery voltage). A short circuit to ground and a line discontinuity will be recognized when the output stages are locked, while a short circuit to the battery voltage is recognized when the output stages are conducting. The output stage is immediately no longer activated when a fault arises. |
||
| 8 | In the event of a short circuit to ground, the corresponding fuel injector is continuously open. | ||
