Are you experiencing trouble with your John Deere tractor and seeing the 94.18 code appear? You’re not alone. This low fuel pressure code can cause performance issues and leave you scratching your head. But don’t worry, we’ve got you covered with the solutions you need.
When this code shows up, it’s often accompanied by other codes like 94.17 and 1569.31, indicating slightly lower fuel pressure and a derate condition respectively. So, what could be causing this issue?
One possible culprit is a plugged fuel filter or a clogged sediment bowl screen. These components can restrict the flow of fuel and contribute to low pressure. Check and clean or replace these parts, making sure the fuel pick-up line from the tank is clear as well.
Another potential cause is a faulty electric fuel pump. Over time, these pumps can wear out or become clogged, leading to inadequate fuel delivery. Inspect the electric fuel pump and consider replacing it if needed.

Common Causes and Solutions for the 94.18 John Deere Code
The 94.18 John Deere code can be caused by various factors, but two common culprits are wiring issues and a faulty check valve in the fuel line. Wiring problems, especially with the wiring going to the bottom of the water separator, can trigger this code. It is crucial to thoroughly inspect the wiring and address any loose connections or damage that may be present. Keeping the wiring in optimal condition can help prevent the 94.18 code from appearing.
Another potential cause of the 94.18 John Deere code is a malfunctioning check valve in the fuel line. The check valve helps regulate the flow of fuel, and if it is faulty, it can lead to low fuel pressure, triggering the code. To determine if the check valve is the issue, it is advisable to conduct a thorough inspection and test. If the check valve is found to be defective, it should be replaced with a genuine John Deere part to ensure proper functioning.
Additionally, it is important to mention that the 94.18 code can sometimes be triggered by a faulty seat sensor. The seat sensor is responsible for detecting whether the operator is seated, and if it malfunctions, it can cause the code to appear. If none of the previous causes are found to be the issue, it may be worth checking the functionality of the seat sensor and replacing it if necessary.
By addressing these common causes, such as wiring issues, a faulty check valve, or a malfunctioning seat sensor, you can effectively resolve the 94.18 John Deere code and ensure optimal performance of your equipment.
