How to Fix B1277 Servo Motor Potentiometer Foot Circuit Open

Introduction

If you’re experiencing the B1277 error code on your car, it means that there’s an issue with the servo motor potentiometer foot circuit. This can be a frustrating problem to deal with, but fortunately, it’s something that you can fix on your own with a little bit of know-how. In this article, we’ll walk you through the steps you need to take to fix the B1277 error code and get your car back on the road.

Step 1: Diagnose the Problem

Before you can fix the B1277 error code, you need to diagnose the problem. This can be done using an OBD-II scanner, which will give you a code that corresponds to the issue. In this case, the code will be B1277. Once you have the code, you can start to troubleshoot the problem.

Step 2: Check the Wiring

The first thing you should do is check the wiring for any signs of damage or wear. Look for frayed wires, loose connections, or any other issues that could be causing the problem. If you find any issues, you’ll need to repair or replace the wiring as necessary.

Step 3: Check the Potentiometer

If the wiring looks good, the next step is to check the potentiometer. This is a small device that measures the position of the servo motor. To check the potentiometer, you’ll need to use a multimeter to test the resistance. If the resistance is outside of the normal range, you’ll need to replace the potentiometer.

Step 4: Check the Servo Motor

If the wiring and potentiometer both look good, the next step is to check the servo motor. This is the device that controls the movement of the throttle. To check the servo motor, you’ll need to remove it from the car and test it using a multimeter. If the servo motor is faulty, you’ll need to replace it.

Step 5: Reassemble and Test

Once you’ve identified and fixed the problem, it’s time to reassemble everything and test the car. Start the engine and make sure that the B1277 error code is no longer appearing. If everything looks good, take the car for a test drive to make sure that everything is working properly.
