How to Fix B1376 Oil Change Lamp Circuit Short to Battery

Introduction

If you’re experiencing the B1376 error code on your car, it means that there’s a short circuit in the oil change lamp circuit that’s causing it to stay on. This can be a frustrating issue 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 B1376 error code and get your car running smoothly again.

Step 1: Check the Wiring

The first thing you should do when you encounter the B1376 error code is to check the wiring. Look for any loose or damaged wires that could be causing the short circuit. If you find any, you’ll need to replace them or repair them as necessary. Be sure to disconnect the battery before you start working on the wiring to avoid any electrical shocks.

Step 2: Check the Oil Change Lamp

If the wiring looks good, the next thing you should check is the oil change lamp itself. Make sure that it’s not damaged or burnt out. If it is, you’ll need to replace it with a new one. You can find replacement oil change lamps at most auto parts stores.

Step 3: Check the Oil Pressure Sensor

If the wiring and oil change lamp are both in good condition, the next thing you should check is the oil pressure sensor. This sensor is responsible for detecting the oil pressure in your car’s engine and sending a signal to the oil change lamp when it’s time for an oil change. If the sensor is faulty, it could be causing the short circuit that’s triggering the B1376 error code.

To check the oil pressure sensor, you’ll need to use a multimeter to test the resistance of the sensor. If the resistance is outside of the normal range, you’ll need to replace the sensor with a new one.

Step 4: Reset the Error Code

Once you’ve identified and fixed the issue that’s causing the B1376 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. Once the code has been reset, start your car and make sure that the oil change lamp turns off.

Conclusion

Fixing the B1376 error code may seem daunting at first, but with a little bit of patience and know-how, it’s something that you can easily do on your own. By following the steps outlined in this article, you’ll be able to identify and fix the issue that’s causing the short circuit and get your car running smoothly again.
