Check the control signal while the Oil Injector test
is running. Set the digital multimeter to the fre-
quency setting or the Hertz (Hz) scale.
•
Meter should read 130 to 150 Hz.

Results:
•
If voltage and control signal readings at pin B
are within range, the EMM and wiring are not at
fault.
•
If voltage at pin B is not within range, check volt-
age at pin A (white/red wire) of oil pump electri-
cal connector.
Connect positive meter lead to pin A (white/red
wire) of oil pump electrical connector. Observe
voltage at pin A.
•
Voltage at pin A should be approximately 30 V.
Start the engine. Observe voltage at pin A.
•
The voltage at pin A should be approximately
55 V.
Results:
•
If voltage is not within range, refer to Oil Pump
Circuit Tests on p. 200, and Oil Pump Resis-
tance Test on p. 201.
•
No voltage reading should result in Code 34;
Crankcase Oil Pump Open Circuit. Refer to
System Voltage Test on p. 122.

Cylinder Oil Pump
The EMM controls the pump by providing ground
through pin 10 (blue/orange wire) of the J3 con-
nector and pin B (blue/orange wire) of the oil
pump connector.
Use a digital multimeter calibrated to a scale that
reads 55 V (DC) to measure voltage between the
oil pump electrical connector and engine ground.
Connect negative meter lead to ground.
Use an appropriate test probe lead to connect
positive meter lead to pin B (blue/orange wire) of
oil pump electrical connector.
