Signal shape and setpoint values
The engine control unit reads in the sensor signal and then compares that signal against a template in its memory unit. By comparing the sensor signal against this saved template, the precise position of the camshaft or the deviation is identified.
| Index | Explanation |
|---|---|
| 1 | Intake camshaft |
| 2 | Exhaust camshaft |
| 3 | Intake camshaft signal |
| 4 | Exhaust camshaft signal |
| 5 | Reference mark for top dead center, cylinder 1 (ignition) |
| 6 | Cylinder |
Observe the following setpoint values for the intake camshaft sensor:
| Size | Value |
|---|---|
| Voltage range | 6 to 16 Volts |
| Maximum operating current | Less than 15 A |
| Engine speed range | 0 to 4000 rpm |
| Air gap range | 0.4 to 2.0 mm |
| Maximum output current | 20 mA |
| Temperature range | -40 °C to 160 °C |
