The P1810 code has a long, complex name, but it boils down to one of two issues. The first is an issue with your transmission control module determining the line pressure in your vehicle. The name refers to the transmission fluid pressure (TFP) valve, which is part of your automatic transmission and handles the pressure for your transmission fluid, which helps your transmission work more effectively. The other is issues with your 4-Wheel Drive Low, also called the 4WD Low, which helps your vehicle improve torque when dealing with certain off-roading conditions.
More About the P1810 Code
This is a unique code because it has two potential descriptions, which are connected but can also come up individually. The 4WD Low range is generally for specific off-roading conditions that make traction very difficult. That may include deep sand, for example, which can give your wheels significantly more traction, giving you more torque for the terrain you’re dealing with. This code also tends to be related to Ford vehicles specifically; if you have another type of vehicle with a 4WD Low range, your vehicle may give you different codes.

What Are the Symptoms of a P1810 Code?
Symptoms of the P1810 code can range dramatically, including anything from an illuminated check engine light to issues with very hard shifting or even your vehicle moving into Limp Mode, which will cause a number of things to stop working within your vehicle, including your air conditioner and some of your lights. Whether or not Limp Mode will turn on in your vehicle will often depend on the precise make and model.
What Are Some Causes of a P1810 Code?
The P1810 code’s causes will depend on which definition your vehicle’s code is sending. For problems with the TFP valve, you’re most likely to see issues with a poor electrical connection or a short circuit to the TFP Valve Position Switch. However, if you’re experiencing issues with the 4WD Low, the cause is indicated in the definition – the battery and the 4WD Low indicator have had a short circuit.
How Serious Is the P1810 Code?
The TFP valve code is generally considered more serious than the 4WD Low code. The TFP valve is an integral part of your transmission, which is why issues with it can turn on Limp Mode in your vehicle. If you see these problems, you should hurry to an expert to get help with it. On the other hand, the 4WD Low code is less serious but can still be important, especially if you regularly use your 4WD Low setting. Regardless of the problems you’re seeing, get help as soon as possible for the best results.
Can I Still Drive with a P1810 Code?
In most cases, your vehicle will physically be able to drive if you’re experiencing the P1810 code. However, that doesn’t mean it’s a good idea to drive. If the problem lies with the TFP valve, then you’re going to be putting excess pressure on the transmission every time you drive, which can lead to serious problems, including significant amounts of damage to your transmission. If the problem is with the 4WD Low option, then you’ll experience issues if you’re in a situation where you need more torque for your vehicle.
How Easy Is It to Diagnose a P1810 Code?
The diagnosis process for the P1810 code is heavily impacted by the fact that it can have two different meanings. Both of those meanings can be very serious, so it is important to check out the definition of the code and see which issue your vehicle is experiencing. From there, you may need special equipment, knowledge, and experience that a DIY hobbyist is unlikely to have. These are all reasons why many people choose to consult an expert for the P1810 code.
How Difficult Is It to Inspect a P1810 Code?
The inspection process for the P1810 code, regardless of the definition for your vehicle, relies heavily on your preexisting knowledge of what a healthy vehicle is supposed to look like for you. Many hobbyists don’t have a lot of technical knowledge surrounding the healthy function of their vehicle, and you might not have all the knowledge that will help you understand the problem. Instead, it’s probably best to talk to an expert.
