Check of sensor, crankcase
pressure
1. Turn off engine
2. Disconnect the charge air pressure sensor con-
nector block and connect the 4-pin adapter
9998534 between the charge air pressure sensor’s
connector block and the engine cable harness.
Then connect the multimeter 9510060 between
measurement points 1–4.
3. Turn on the control voltage.
4. Measure with the multimeter set to voltage mea-
surement. Check that the multimeter shows 5.0
volt.
5. Then connect the multimeter between measure-
ment points 2 –4. Voltage should be about 3 V at
normal atmospheric pressure.
Check of sensor, fuel pressure
1. Turn off engine
2. Disconnect the oil pressure sensor connector
block and connect the 7-pin adapter 9998567 be-
tween the oil pressure sensor’s connector unit and
the engine cable harness. Then connect the multi-
meter 9510060 between measurement points 1–4.
3. Turn on the control voltage.
4. Measure with the multimeter set to voltage mea-
surement. Check that the multimeter shows 5.0
volt.
5. Now connect the multimeter between measure-
ment points 2 – 4.Voltage should be about 0.5 V
at normal atmospheric pressure.
