How to Fix B1385 Oil Level Lamp Circuit Open

Introduction

If you’re experiencing the B1385 error code on your car, it means that there’s an issue with the oil level lamp 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 B1385 error code and get your car running smoothly again.

Step 1: Check the Oil Level Sensor

The first thing you need to do when dealing with the B1385 error code is to check the oil level sensor. This sensor is responsible for monitoring the oil level in your car and sending a signal to the dashboard when the oil level is low. If the sensor is faulty, it can cause the B1385 error code to appear.

To check the oil level sensor, you’ll need to locate it on your car. The sensor is usually located near the oil filter or oil pan. Once you’ve located the sensor, disconnect it from the wiring harness and use a multimeter to test it. If the sensor is faulty, you’ll need to replace it.

Step 2: Check the Wiring

If the oil level sensor is working properly, the next thing you need to check is the wiring. The B1385 error code can also be caused by a problem with the wiring that connects the sensor to the dashboard. To check the wiring, you’ll need to use a multimeter to test the continuity of the wires.

Start by disconnecting the wiring harness from the sensor and the dashboard. Then, use the multimeter to test the continuity of each wire. If you find a wire that has no continuity, you’ll need to repair or replace it.

Step 3: Check the Dashboard

If the oil level sensor and wiring are both working properly, the next thing you need to check is the dashboard. The B1385 error code can also be caused by a problem with the dashboard itself. To check the dashboard, you’ll need to remove it from your car and inspect it for any signs of damage or wear.

If you find any damage or wear on the dashboard, you’ll need to replace it. You can either purchase a new dashboard from a dealer or salvage yard, or you can have your existing dashboard repaired by a professional.

Step 4: Reset the Error Code

Once you’ve fixed the problem that was causing the B1385 error code, you’ll need to reset the code. To do this, you’ll need an OBD-II scanner. Connect the scanner to your car’s OBD-II port and follow the instructions to reset the error code.
