Crank Angle Sensor
- Use special tool test harness (MB991658) to connect B-121 crank angle
sensor intermediate connector, and measure at pick-up harness.
- Engine: Idling
- Transmission: Neutral <M/T> or P range
<A/T>
- Voltage between terminal No. 2 and earth.
Camshaft Position Sensor
- Use special tool test harness (MB991709) to connect B-114 camshaft
position sensor connector, and measure at pick-up harness.
- Engine: Idling
- Transmission: Neutral <M/T> or P range
<A/T>
- Voltage between terminal No. 2 and earth.
OK: Output waveform timings of both sensors are the same as
the check procedure (Refer to ) using an
oscilloscope.
