Description:

The ECU 000100.01 (100.01) error code is triggered when the engine oil pressure registered is extremely low on John Deere engines equipped with an oil pressure sensor or when the oil pressure switch opens after the engine speed exceeds cranking speed for several seconds. This critical condition may indicate an actual low oil pressure situation due to inadequate oil levels, oil pump failure, or severe engine wear.

Reaction:

The engine control system may activate safety protocols, including reducing engine power or stopping the engine to prevent damage.

Recommendations:

• Check Oil Levels and Quality: Ensure the engine oil is at the correct level and condition. Replace if old or contaminated.
• Inspect Oil Pump and Oil Filter: Check the oil pump for proper operation and ensure the oil filter is not clogged.
• Examine Sensor or Switch: Test the functionality of the oil pressure sensor or switch. Replace if faulty.
• Immediate System Shutdown and Inspection: If low oil pressure is confirmed, shut down the engine immediately and inspect for internal damage or wear.

Note:

Low engine oil pressure is a critical issue that requires immediate attention to prevent engine failure. Regular oil changes, along with frequent monitoring of oil levels and system pressures, are essential for maintaining engine health and performance.
