Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
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.
Example 6-cylinder diesel engine
| Item | Explanation |
|---|---|
| 1 | Intake camshaft |
| 2 | Intake camshaft signal |
| 3 | Reference mark for top dead center, cylinder 1 (ignition) |
| 4 | Cylinder |
Observe the following setpoint values for the camshaft sensor:
| Variable | Value |
|---|---|
| Voltage range | 6 to 16 Volts |
| Engine speed range | 0 to 4000 rpm |
| Air gap range | 0.4 to 1.9 mm |
| Maximum output current | 20 mA |
| Temperature range | -40 °C to 160 °C |
