3. Test the Sensor (The "Ohm" Test)

If you have a multimeter, you can test the resistance of the sensor itself.

• Set the multimeter to Ohms (Ω).
• Touch the probes to the sensor terminals.
• Typical Range: A functional sensor usually reads between 800 to 1200 Ohms (though you should check your specific model's service manual for exact specs).
• If the meter reads "Open Line" (OL) or 0 Ohms, the sensor is dead and needs replacement.

Step-by-Step Diagnostic Procedure

Before replacing any parts, follow this systematic diagnostic flow. You will need a multimeter, contact cleaner, dielectric grease, and preferably an electronic service tool (e.g., New Holland EST or a diagnostic adapter with AgriCommand software). New Holland 3297 Error Code
