Function check using actual values with HHT (Testing engine)
Actual value no. | Actual value | Specified value |
| Coolant temperature | > 80 °C |
| Engine speed | 750 50 rpm |
| Injection time | 2.1 - 2.6 ms |
| Lambda control (in the event of complaint the Lambda control must be measured at idle speed and at 2500 rpm with the purge line (to engine) disconnected and sealed) | 0 10 % |
| Throttle valve angle | 0.3 - 2.5 ° |
| Intake manifold absolute pressure | 600 50 mbar |
| O2- sensor voltage (fluctuates around 300 mV after 2 min) | - 200 to +1000 mV |
| Idle speed self-adaptation (idle speed basic position, 0.0 ms. When idling at < 0.0 ms (neg. value) fuel mixture has a tendency towards "rich". When idling at > 0.0 ms (pos. value) fuel mixture has a tendency towards "lean" | 0 0.2 ms |
| Part-load self-adaptation factor (part-load basic position, 1.0. tendency towards "rich" < 1.0 tendency towards "lean" > 1.0) | 0.85 - 1.15 |
| Ignition advance angle (The ignition advance angle is also used to stabilize idle speed and therefore in an extreme case the ignition advance angle may briefly deviate 10 ° from the specified value) | 5 5 °CKA before TDC |
| PEC resistance trimming plug (PEC resistance trimming plug correction position) | 1 |
| Drive stage (Selector lever position P/N) | Display: OFF |
| Inertia fuel shut-off (closed throttle position) Engine speed > 2100 rpm | Display: OFF Display: ON |
| Ignition coil combustion period | 0.65 - 2.6 ms |
| Ignition coil combustion voltage | > 28 V |
| Ignition coil fault counter | < 255 |
| Exhaust gas valve | Display: CLOSED |
