Cid 0091 Fmi 03 Accelerator Pedal - Voltage Above Normal - Perkins 1106D Troubleshooting Manual

88
Troubleshooting Section
The reduction of speed is determined by the current
speed of the engine.
When a fault is detected and the engine is above the
predetermined safe speed, the engine will reduce
speed to the safe speed.
When a fault is detected and the engine is below the
predetermined safe speed, the engine will match the
correct speed.
The throttle switch is ignored by the ECM until the
fault is repaired.
The throttle switch will also be ignored by the ECM
until the keyswitch has been turned to the OFF
position and then back to the ON position.
Troubleshooting:
Proceed to "Test Step 1" if the engine is equipped
with a throttle switch.
Proceed to "Test Step 2" if the engine is equipped
with an analog throttle position sensor.
Test Step 1.
Perform the following diagnostic procedure: "Throttle
Switch Circuit - Test"
Results:
•
OK – STOP.
Test Step 2.
Perform the following diagnostic procedure: "Analog
Throttle Position Sensor Circuit - Test"
Results:
• OK – STOP.
CID 0091 FMI 03 Accelerator
pedal - voltage above normal
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.
•
The power supply for the throttle sensor is within
the expected range.
•
Diagnostic code 0168-01 is not active.
•
On a digital throttle, the reading is greater than 97
percent.
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 configuration screen on the electronic
service tool in order to determine the type of throttle
position sensor that is used on the engine.
If the engine is equipped with an analog throttle
position sensor, proceed to "Test Step 1".
If the engine is equipped with a digital throttle position
sensor, proceed to "Test Step 2".
Test Step 1.
Perform the following diagnostic procedure: "Analog
Throttle Position Sensor Circuit - Test"
Results:
•
OK – STOP.

Test Step 2.
Perform the following diagnostic procedure: "Digital
Throttle Position Sensor Circuit - Test"
Results:
•
OK – STOP.
