Troubleshooting with a
Diagnostic Code
CID 0041 FMI 03 8v Sensor
Power Supply, Voltage More
Than Normal
Conditions Which Generate This Code:
The ECM detects all of the following conditions:
•
The ECM has been powered for at least three
seconds.
•
The ECM reads signal voltage that is above
normal.
System Response:
The ECM will log the diagnostic code. The diagnostic
code may be viewed on the electronic service tool.
The ECM will return the engine to low idle or a safe
speed. The engine will remain at low idle or safe
speed while the diagnostic code remains active.
Possible Performance Effect:
•
Low power
Troubleshooting:
Perform the following diagnostic procedure: "Throttle
Position Sensor Circuit - Test"
Results:
• OK – STOP.
CID 0041 FMI 04 8v Sensor
Power Supply, Voltage Less
Than Normal
Conditions Which Generate This Code:
The ECM detects all of the following conditions:
•
The ECM has been powered for at least three
seconds.
•
The ECM reads signal voltage that is below normal.
System Response:
The ECM will log the diagnostic code. The diagnostic
code may be viewed on the electronic service tool.

The ECM will return the engine to idle or a safe
speed. The engine will remain at idle or safe speed
while the diagnostic codes remain active.
Possible Performance Effect:
•
Low power
Troubleshooting:
Perform the following diagnostic procedure: "Throttle
Position Sensor Circuit - Test"
Results:
•
OK – STOP.
CID 0091 FMI 02 Throttle
Demand Sensor Erratic Or
Intermittent
Conditions Which Generate This Code:
If the engine is equipped with a throttle switch then
the signal from this switch is invalid.
If the engine is equipped with a throttle position
sensor then the signal from the throttle idle validation
switch is invalid.
System Response:
The ECM will log the diagnostic code. The diagnostic
code may be viewed on the electronic service tool.
i01798140
Possible Performance Effect:
The engine speed defaults to low idle or a
predetermined safe speed.
The engine will remain at this speed while the
diagnostic code remains active.
The reduction of speed is determined by the current
speed of the engine.
