: Small leaks in the fuel lines or a failing lift pump can introduce air, causing pressure fluctuations. Recommended Troubleshooting Steps
The DEF injector itself contains an internal solenoid. Over time, the internal coil can fail, short-circuit, or become stuck due to crystallized DEF. 3. DEF Crystallization and Blockages
If the main pump cannot sustain target pressure during high demand, the ECU trips the code.
While less common for this specific code, inspect the wiring harness for the fuel pressure sensor for corrosion or damage, as electrical faults can cause "not plausible" signal readings. СБ Про-Сервіс New Holland 3297 Error Code
A stuck or worn-out fuel injector can cause pressure imbalances. Fuel Restriction:
A blockage in the fuel return line back to the tank can cause pressure to build up beyond safe limits.
The New Holland error code indicates a high positive rail pressure deviation combined with a high fuel flow setpoint . This fault typically points to a leak or mechanical failure within the fuel injection system that prevents the engine from maintaining desired pressure. Error Summary : Small leaks in the fuel lines or
The pressure relief valve on the fuel rail may be failing or leaking fuel back to the tank prematurely. Low-Pressure Line Failures
Look for signs of wear on the high-pressure fuel pump or "sweating" fuel lines. Pressure Test:

New Holland 3297 error code (often appearing alongside other SCR/DEF codes) typically indicates a
DEF is a mixture of high-purity urea and deionized water. When exposed to air, the water evaporates, leaving behind hard white urea crystals. If these crystals clog the dosing valve nozzle or the supply lines, the module will fail to actuate properly, causing the ECU to throw an electrical or pressure fault. 4. Supply Module Pump Failures
Ensure there is no water or excessive additives (like anti-gel) that could interfere with injector operation. Use Diagnostic Tools:
