Before calling a technician, you can perform these basic checks to potentially clear the code:
The supply module contains a small filter that can clog with crystallized urea or debris.
Ensure the battery and alternator are providing steady power, as low voltage can cause the DEF pump to run under-speed. Professional Diagnostics
Error code 3297 translates to "DEF Pressure Low." It indicates that the SCR dosing module is not receiving the required fluid pressure to effectively spray DEF into the exhaust stream. When this happens, the tractor's engine control unit (ECU) may trigger a "derate" mode, significantly reducing engine power to prevent excessive emissions. Common Causes of the 3297 Code
DEF freezes at 11°F (-12°C). If the tank heaters fail in cold weather, ice blocks the lines.
Understanding and resolving the New Holland 3297 error code is essential for maintaining the productivity of your Tier 4B (Final) equipment. This specific fault code typically points to an issue within the Selective Catalytic Reduction (SCR) system, specifically regarding the Diesel Exhaust Fluid (DEF) pressure. What is New Holland Error Code 3297?
If operating in freezing temperatures, move the machine to a heated shop for several hours to ensure no ice is present in the lines.
Damage to the suction or pressure lines prevents fluid from reaching the injector.
The internal diaphragm or motor in the supply module may have reached the end of its life.
If the code persists after basic maintenance, a dealer technician will use the CNH Electronic Service Tool (EST) to perform a "static dosing test." This test manually activates the pump to measure the exact pressure output (typically around 9 bar or 130 psi). If the pump runs but cannot build pressure, the internal supply module likely requires replacement.
