Troubleshooting Section
The ECM will generate a CID 100 FMI 03 diagnostic
code on the Data
Link. The diagnostic code will be
displayed on the diagnostic screen of the electronic
service tool.
Troubleshooting:
Perform the fo
llowing diagnostic procedure:
Perform the following diagnostic procedure: “Engine
Pressure Sens
or Open or Short Circuit - Test”
Results:
OK STOP.
i01798147
CID 0100 FMI 04 Engine Oil
Pressure Sensor Sho rted Low
Conditions W
hich Generate This Code:
The ECM detects all of the following conditions:
The signal voltage that is below normal
The ECM has be
en powered for at least two
seconds.
CID 262-03 5 V
Sensor Power Supply, Voltage
More Than Normal and CID 262-04 5V Sensor
Power Supply, Voltage Less Than Normal are not
active.
System Response:
The ECM will log the diagnostic code. The diagnostic
code may be viewed on the electronic service tool.
The ECM flag
s oil pressure as invalid data and a
default value is used.
Troublesho
oting:
Perform the following diagnostic procedure:
Perform the following diagnostic procedure: “Engine
Pressure Sensor Open or Short Circuit - Test”
Results:
OK STOP.

CID 0100 FMI 10 Engine
Oil P ressu re Sensor, Po w er
Supply Open Ci
rcuit
Conditions Which G enerate This Code:
If the 5 volt co
nnection to the sensor is an open
circuit, this fault will result in a logged code.
The Electroni
c Control Module (ECM) detects all of
the following conditions:
No other CID 02
62 or CID 0102 codes are active.
The engine speed is greater than 600 rpm.
Engine oil pressure signal is within the expected
range for this failure mode.
Engine oil pressure signal remains abnormally
constant because the variations in the sensor
signal are to
osmall.
All of the above conditions occur simultaneously
for a period o
f 10 seconds.
System Response:
The ECM will log the diagnostic code. The diagnostic
code may be viewed on the electronic service tool.
The ECM will
flag the engine oil pressure as invalid
data. The engine oil pressure is set to a default value.
Possible Pe
rformance Effect:
Perform the following diagnostic procedure: Engine
Pressure Se
nsor Open or Short Circuit - Test”
Results:
OK STOP.

it Or Shorted High
Conditions Which G enerate This Code:
The Electr
onic Control Module (ECM) detects all of
the following conditions:
The ECM rea
ds a signal voltage that is above
normal.
