B1954 Seat Front Up/Down Potentiometer Feedback Circuit Failure

How to Diagnose and Solve B1954 Seat Front Up/Down Potentiometer Feedback Circuit Failure Issues


If you’re experiencing issues with your car’s seat adjustment, specifically the front up/down function, you may have a B1954 error code. This code indicates a problem with the seat front up/down potentiometer feedback circuit. In this article, we’ll discuss how to diagnose and solve this issue.

What is a Potentiometer Feedback Circuit?

A potentiometer feedback circuit is a system that measures the position of a component and sends that information to the car’s computer. In the case of the seat front up/down function, the potentiometer measures the position of the seat and sends that information to the computer. This allows the computer to adjust the seat to the desired position.

Diagnosing the Issue

The first step in diagnosing the B1954 error code is to check the wiring and connections of the potentiometer feedback circuit. Look for any loose or damaged wires, and ensure that all connections are secure. If the wiring and connections are in good condition, the next step is to check the potentiometer itself.

To check the potentiometer, you’ll need a multimeter. Set the multimeter to measure resistance and connect the leads to the potentiometer. Move the seat up and down while monitoring the multimeter. If the resistance readings are inconsistent or fluctuate, the potentiometer may be faulty and need to be replaced.

Solving the Issue

If the issue is with the wiring or connections, repair or replace any damaged components. If the potentiometer is faulty, it will need to be replaced. You can purchase a replacement potentiometer from your local auto parts store or online.

To replace the potentiometer, first, disconnect the battery to prevent any electrical shocks. Remove the seat from the car and locate the potentiometer. Disconnect the wiring and remove the potentiometer from the seat. Install the new potentiometer and reconnect the wiring. Reinstall the seat and reconnect the battery.

Tips for Preventing Future Issues

To prevent future issues with the potentiometer feedback circuit, regularly inspect the wiring and connections for any damage or wear. If you notice any issues, repair or replace the affected components immediately. Additionally, avoid putting excessive weight on the seat, as this can cause damage to the potentiometer.


If you’re experiencing issues with your car’s seat front up/down function and have received a B1954 error code, the problem may be with the potentiometer feedback circuit. By following the steps outlined in this article, you can diagnose and solve the issue, ensuring that your car’s seat adjustment functions properly.


1. Can I drive my car with a B1954 error code?

While it’s technically possible to drive your car with a B1954 error code, it’s not recommended. The seat front up/down function may not work properly, which can be a safety hazard.

2. How much does it cost to replace a potentiometer?

The cost of replacing a potentiometer can vary depending on the make and model of your car and where you purchase the replacement part. On average, you can expect to pay between $50 and $150 for a replacement potentiometer.

3. Can I replace the potentiometer myself?

Replacing the potentiometer requires some technical knowledge and experience with car repairs. If you’re not comfortable working on your car, it’s best to take it to a professional mechanic. However, if you have experience with car repairs and feel confident in your abilities, you can replace the potentiometer yourself.
