What does the P1810 code mean?
The P1810 code is a transmission code that indicates a malfunction in the pressure control solenoid valve. This valve regulates the pressure of the transmission fluid, which is essential for the proper operation of the transmission.
If this valve fails, it can cause a variety of transmission problems, such as harsh shifting, slipping, and failure to shift. It is important to address this issue promptly to avoid costly repairs or transmission replacement.
What causes the P1810 code?
The P1810 code can be caused by several factors, such as a faulty pressure control solenoid valve, a damaged valve body, or a malfunctioning wiring harness. Below are the potential causes of the P1810 code:
Faulty pressure control solenoid valve
This valve can become clogged or simply fail over time, leading to a malfunction. If the valve fails, it becomes impossible for the TCM to use the information regarding the transmission fluid pressure to properly manage torque conversion and power output while switching gears.
Damaged valve body
If the valve body is damaged, it may not be able to regulate the transmission fluid pressure properly, resulting in the P1810 code.
Malfunctioning wiring harness
If there is a problem with the wiring harness that connects the transmission to the engine control module, it may cause the P1810 code to appear.
Symptoms of the P1810 code may include harsh shifting, slipping, and failure to shift.
Which car models does the P1810 code affect the most?
The P1810 code is most commonly found in GM vehicles, including Chevrolet, GMC, and Cadillac. Our team wanted to verify this statement by going through the available records to figure out which cars may be more susceptible to code P1810 and why. Here’s a list of the models that are influenced by this code the most:
- Chevy Impala: This model has been known to experience issues with the transmission fluid pressure sensor circuit, which can trigger the P1810 code.
- Chevy Equinox: The Equinox has a history of transmission problems, including issues with the pressure control solenoid that can cause the P1810 code.
- Chevy Malibu: Like many other Chevy models, the Malibu has also been known to experience issues with the transmission pressure control solenoid that can trigger the P1810 code.
- Saturn Vue: The Vue has a reputation for transmission problems, including a faulty pressure control solenoid that can cause the P1810 code.
How to diagnose the P1810 code
To diagnose the P1810 code, a mechanic will need to use specialized diagnostic tools and equipment. While this is what usually happens, you don’t have to be a professional to diagnose the problem behind the code P1810, so here’s what you may be able to do:
Check for other error codes
You can use an OBD2 scanner tool to check for any other error codes that may be present in the vehicle’s computer system. This method also helps if it reveals other OBD2 codes that may be connected with the P1810 code which helps narrow down the possible reasons.
Check the transmission fluid
The mechanic should check the transmission fluid level and condition to ensure that it is not the cause of the problem. You can do this even by yourself and you should also check the condition of the transmission fluid. If you notice any signs of contamination or leaks, you may need to flush the system and top up the fluid to fix the code.
Check the pressure control solenoid valve
The mechanic should check the pressure control solenoid valve and its wiring harness for any defects. The valve is one of the most common reasons behind the code’s activation, so it’s natural to check this valve and replace it if needed.
Check the valve body
The mechanic should inspect the valve body for damage or wear and tear. This component can be either electronic or hydraulic and regardless of the case, it can impact the code P1810 and the way your gearbox shifts through the gears if it goes bad.
How to fix the P1810 code
Fixing the P1810 code will depend on the underlying cause of the problem. Here are the potential fixes for each cause of the code:
Faulty pressure control solenoid valve
The valve may need to be replaced, and the cost can range from $200 to $500. It’s among the most common solutions and you’ll need a qualified mechanic to do the job since it’s not wise to manually tamper with the transmission if you aren’t a professional.
Damaged valve body
The valve body may need to be replaced, and the cost can range from $500 to $1500. Without a properly operational valve body, the clutch can’t be engaged at the right time and it compromises the shifting precision. So, replacing it could solve the code and it’s once again best to leave it to a trusted mechanic.
Malfunctioning wiring harness
The wiring harness may need to be repaired or replaced, and the cost can range from $100 to $300.
It is important to note that attempting to fix the P1810 code without the proper knowledge or experience can lead to further damage to the transmission. If unsure, it is best to consult a professional mechanic.
How to prevent the P1810 code
After properly diagnosing and fixing code P1810, you can rely on some preventive measures to keep the issue at bay and prevent it from happening again. Here are some ways to prevent the occurrence of the P1810 code:
- Regular maintenance according to the manufacturer’s recommended schedule
- Frequently replacing transmission fluid
- Timely replacing the filters
- Having frequent transmission system checks
Also, if you notice any signs of transmission problems such as slipping, delayed engagement, or harsh shifting, it’s important to have your vehicle inspected by a qualified mechanic as soon as possible. Addressing these issues early on can prevent them from developing into more serious problems that could trigger the P1810 code.
Our take
Ultimately, the code P1810 is a pretty strange one since it may lead to a complete transmission breakdown in the long run but it doesn’t seem that serious at first. That’s why we wanted to bring you the main details on fixing the code to prevent you from looking the other way and waiting until the code triggers an even bigger problem.
What are the symptoms of the P1810 code?
The symptoms of the P1810 code may include harsh shifting, delayed engagement, slipping, or failure to shift.
How serious is the P1810 code?
While the P1810 code does not necessarily indicate a serious problem, it can cause issues with the performance and reliability of your vehicle’s transmission system if left unaddressed.
Can I still drive my vehicle with a P1810 code?
It is generally not recommended to drive your vehicle with an unresolved P1810 code as it can lead to more serious transmission problems and potentially costly repairs down the line.
