New Holland is a globally known agricultural machinery designer and manufacturer. They have an extensive range of agricultural equipment, including balers, self-propelled sprayers, tractors, forage harvesters, combine harvesters, seeding equipment, utility vehicles, and much more.
All these types of machinery are designed with advanced control systems. That’s because they show fault codes as a warning for defects in the machinery/vehicle.
So, if there is a fault code appearing on your New Holland dashboard display, you must act quickly to ensure on-time repair and prevent permanent damages.
How to Clear New Holland Fault Codes?
Clearing or fixing the fault codes is not possible without understanding the root cause or having basic knowledge. The fault codes on New Holland vehicles are numerical codes, which indicate a specific issue in the engine or other component.
Every fault code signals a unique issue and you can consult the manual to determine the right solutions.
On the other hand, if you cannot fix the fault code on your own, you must hire a mechanic. In addition, you can contact the customer care center to gain information about the fault code along with its meaning and solution.
However, there are some common fault codes that you are likely to see on the New Holland screen.
- ENG – 111
ENG – 111 is caused by the failure of the engine controller or some other hardware failure. The engine controller is responsible for monitoring the piston’s position with the help of crankshaft position sensors.
In addition, it also monitors the spark plugs’ timing. Consequently, it works on regulating the spark plugs. The engine controller is also responsible for accepting commands coming from the pedal.
So, when the engine controller is not working properly, the New Holland machinery will fail to operate but it can be fixed by resetting the engine control module. You must hire a mechanic for resetting the module or get it replaced if the New Holland machinery is old.
- ENG – 115
This fault code means that the camshaft sensor or engine speed sensor has failed. The camshaft sensor is usually a small part of the engine and is responsible to ensure that air and fuel are combusting at the right time in the engine’s combustion chamber.
On the other hand, the engine speed sensor is designed to communicate with the engine control unit to keep it running.
In simpler words, it calculates the rotational speed of the wheels to determine the speed of the vehicle. So, if any of these sensors are damaged, the engine’s performance will be stalled and the only solution is to get the sensors replaced because they are too small to be repaired.
- ENG – 122 & ENG – 123
The boost pressure sensor is responsible for showing the air pressure within the engine. In addition, it measures the pressure before a throttle valve, which is used to calculate the correction value.
So, when the voltage in this sensor is too high, it leads to ENG – 122, while ENG – 123 appears with a low voltage. In either case, the engine power and acceleration will be negatively impacted.
So, check the intake pipe of the throttle valve to locate the boost pressure sensor and use the multimeter to check the voltage. In case the voltage is higher or lower than the recommended value, you will need to get it replaced.
However, before you replace it, try cleaning it with alcohol or petrol to see if it fixes the problem.
- ENG – 131 & 132
The hand throttle is an important part of agricultural machinery and is integrated with the armrests and control panel for regulating the speed. It is connected with the position potentiometer, which helps determine the throttle valve’s opening angle.
The data is passed to the control unit for calculating the required fuel level. However, when the voltage is too high on the potentiometer, the display shows ENG – 131 error code, while low voltage causes ENG – 132.
The voltage fluctuation is caused by obstructions in the transmission lines, which means you have to get the wiring and transmission system checked by a professional. Usually, the mechanics overhaul the transmission lines to fix the voltage issues.
- ENG – 143
The right oil pressure is essential for the New Holland machinery to operate. It is because the oil helps lubricate the moving parts and ensures the optimal functioning of these parts. When this oil passes through the engine, it builds up pressure and the pressure ensures that the oil is reaching every component.
However, when the oil pressure level drops below the normal value, ENG – 143 will appear on the screen. The easiest way of fixing the low oil pressure level is to opt for high-viscosity oil.
That’s because the change in viscosity can cater to the increased bearing clearance, resulting in the normalization of the pressure level. So, if you are using oil with a viscosity of 5W-20, it’s best to switch to 10W-30.
- ENG – 146
The coolant is an important part of the engine because it transfers the heat and prevents engine damage caused by boiling and freezing. Since heat is only transmitted with fluid in the system, it is critical to prevent evaporation and/or freezing of the coolant.
In fact, if the coolant temperature exceeds the normal limit, ENG – 146 will appear on the display.
The coolant temperature increases when there are leaks in a cooling system, mineral deposits and corrosion in hoses, and broken pumps. So, you have to check the cooling system to fix the leaks and clear the mineral deposits and corrosion from the hoses to ensure seamless flow and temperature regulation.
We recommend that you hire a mechanic for replacing the broken pump and fixing the leaks in New Holland’s cooling system.
- ENG – 153 & ENG – 154
Commonly known as the IAT sensor, the intake manifold temperature sensor plays a critical role in the engine’s efficiency. It detects the air temperature that’s coming into the engine for sending this information to the main computer of the vehicle.
However, the voltage fluctuation in the IAT sensor can cause ENG – 153 (higher voltage) and ENG – 154 (lower voltage).
Also, when these fault codes appear on the display, New Holland machinery will misfire and the acceleration will be slow. The high voltage is caused when the air filter is dirty, so clean it properly and make sure you replace the air filters on time.
However, if cleaning and/or replacing the air filter doesn’t work, you will need to replace the sensor.
- ENG – 211
Proper communication and data transfer are essential for the New Holland machinery to work properly. However, if there are communication issues with the transmission controller or armrest, you will get ENG – 211 on the display.
It is usually caused by an error in the transmission lines, and since this transmission system is complicated, you should contact a professional mechanic.
- ENG – 329
The fuel pump is responsible for generating pressure and volume to make sure the fuel is pushed from the fuel tank to the injectors. Correspondingly, the machinery/vehicle starts moving normally as the fuel flow is optimized.
However, when the fuel pump starts overpumping, it leads to ENG – 329 on New Holland. It results in an overflowing carburetor and the engine tends to stall. As far as the solution is concerned, you must replace the fuel pump .
- ENG – 319
New Holland has integrated a real-time clock in the controller system, which is responsible for determining the right time to execute a function. However, there are times when the clock loses power and the functionality of New Holland machinery is stalled.
The solution is to replace the clock and you also need to replace the battery to make sure the clock is properly powered.
The Bottom Line
New Holland is a popular brand name when it comes down to agricultural equipment and machinery. However, some fault codes are extremely common in the machinery and the solutions in this article should help you regulate New Holland’s performance.
In case you have to repair or replace something, you must hire a mechanic to yield long-term results.
