Diagnostic code 0168-01 is not active.
System Response:
The ECM will log the diagnostic code and the ECM
will trigger a snapshot. The check engine lamp will
illuminate while this diagnostic code is active. An
active diagnostic code may not cause any noticeable
effect on engine response unless the voltage drops
below 6.5 VDC.
Possible Performance Effect:
The engine may be limited to low idle.
Troubleshooting:
This signal is not normally used in this application.
If this diagnostic code is observed, check the
associated wiring on the engine.
Refer to the Engine Electrical Schematic.
Results:
•
OK – STOP.
i02752017
CID 0091 FMI 03
Conditions Which Generate This Code:
The Electronic Control Module (ECM) detects the
following conditions:
•
ECM has been powered for at least 3 seconds.
•
A signal voltage for the throttle position is above
normal.
•
Diagnostic code 0168-01 is not active.
System Response:
If equipped, the warning light will come on. The ECM
will trigger a snapshot. The ECM logs the diagnostic
code if the engine is running. The diagnostic codes
can be viewed on the electronic service tool. The
ECM will return the engine to low idle.
Possible Performance Effect:
•
Low power
•
Reduced engine speed
Troubleshooting:
Monitor the con
fi
guration screen on the electronic
service tool in order to determine the type of speed
demand circuit that is used on the engine.
If the engine is equipped with an analog speed
demand circuit, proceed to “Test Step 1”.
If the engine is equipped with a digital speed demand
circuit, proceed to “Test Step 2”.
Test Step 1.
Perform the following diagnostic procedure: “Speed
Demand Circuit (Analog) - Test”
Results:
•
OK – STOP.
Test Step 2.
Perform the following diagnostic procedure: “Speed
Demand Circuit (Digital) - Test”
Results:
•
OK – STOP.

CID 0091 FMI 04
Conditions Which Generate This Code:
The Electronic Control Module (ECM) detects all of
the following conditions:
•
The ECM has been powered for at least 3 seconds.
•
A signal voltage for the throttle position is below
normal.
•
Diagnostic code 0168-01 is not active.
System Response:

will trigger a snapshot. The ECM logs the diagnostic
code if the engine is running. The diagnostic codes
can be viewed on the electronic service tool. The
ECM will return the engine to low idle.
Possible Performance Effect:
