<Crank angle sensor>
- Use the test harness (MB991709) to connect crank angle sensor connector, and measure at the pick-up harness.
- Engine: Idling
- Transmission: P range
- Check the voltage between the crank angle sensor connector (SGT line) and body earth.
|
|
<Camshaft position sensor>
- Use the test harness (MB991709) to connect camshaft position sensor connector, and measure at pick-up harness.
- Engine: Idling
- Transmission: P range
- Check the voltage between the camshaft position sensor connector (SGC line) and body earth.
