Engine Speed Sensor Failed in Engine Controller
Cause:
The Data Bus signaled that the engine speed data is in error or not available from the engine controller.
Possible failure modes:
1. The engine speed sensor failed in the engine controller (most cases).
2. The engine controller is configured in the system where there is no engine controller.
3. Software execution error in the engine controller (small chance).
Solution:
This fault code is for tractors equipped with an engine controller. The instrumentation controller receives the engine
speed signal from the engine controller through the Data Bus.
1. Make sure the engine is running properly.
2. Check that the instrumentation controller is configured correctly.
3. Check for engine fault codes. If any exists, follow the corresponding corrective action. See the engine service
manual for diagnosing procedures.
Engine Overspeed
Cause:
The data bus signaled that the engine speed data indicates that the engine RPM exceeded a preset limit.
Possible failure modes:
1. The engine speed has exceeded a preset limit.
Solution:
The instrument cluster has received the engine speed signal from the engine controller through the data bus.
1. Take precautions to avoid overspeed the engine. Select a lower gear when traveling down inclines, especially
when pulling a heavy load.
Engine Oil Pressure Sensor Failed in Engne Controller
Cause:
The Data Bus signaled that the engine oil pressure information is in error or not available from engine controller.
Possible failure modes:
1. Engine oil pressure sensor failed in engine controller (most cases).
2. The engine controller is configured in the system when there is no engine controller.
3. Software execution error in the engine controller (small chance).
Solution:
This fault code is for tractors equipped with an engine controller. The instrumentation controller receives the oil
pressure signal from the engine controller through the Data Bus.
1. Make sure the engine is running properly.
2. Check that the instrumentation controller is configured correctly.
3. Check for engine fault codes. If any exists, follow the corresponding corrective action. See the engine service
manual for diagnosing procedures.
