Some key functions of a Fuel Pressure Sensor in a cotton picker include:

1. Monitoring fuel pressure: The sensor continuously monitors the pressure of the fuel in the fuel system of the cotton picker. This information is crucial for the engine control system to adjust the fuel delivery and optimize combustion for efficient operation.

2. Ensuring proper fuel delivery: Maintaining the correct fuel pressure is essential for delivering the right amount of fuel to the engine cylinders for combustion. The Fuel Pressure Sensor helps to ensure that the fuel delivery system is functioning properly and that the engine is receiving the correct amount of fuel under varying operating conditions.

3. Detecting fuel system issues: The Fuel Pressure Sensor can also help detect potential fuel system issues, such as fuel leaks, blockages, or pump malfunctions, by monitoring fluctuations in the fuel pressure. If the sensor detects abnormal pressure levels, it can trigger alerts to the control system, prompting corrective action to prevent engine damage or failure.
