How to Fix B1377 Oil Change Lamp Circuit Failure

Introduction

If you own a car, you know how important it is to keep it in good condition. Regular maintenance is essential to ensure that your car runs smoothly and safely. One of the most important aspects of car maintenance is changing the oil. However, sometimes, you may encounter an error code, such as B1377, which indicates an oil change lamp circuit failure. In this article, we will discuss how to fix B1377 oil change lamp circuit failure.

What is B1377 Oil Change Lamp Circuit Failure?

B1377 is an error code that indicates a problem with the oil change lamp circuit. The oil change lamp is a warning light that indicates when it is time to change the oil in your car. When the oil change lamp circuit fails, the warning light may not work correctly, and you may not receive a warning when it is time to change the oil.

Step-by-Step Guide to Fix B1377 Oil Change Lamp Circuit Failure

Step 1: Check the Oil Change Lamp Bulb

The first step in fixing B1377 oil change lamp circuit failure is to check the oil change lamp bulb. The bulb may be burnt out, which can cause the circuit to fail. To check the bulb, remove the oil change lamp from the dashboard and inspect the bulb. If the bulb is burnt out, replace it with a new one.

Step 2: Check the Oil Change Lamp Circuit

If the bulb is not the problem, the next step is to check the oil change lamp circuit. The circuit may be damaged or broken, which can cause the warning light to fail. To check the circuit, use a multimeter to test the voltage at the oil change lamp connector. If there is no voltage, the circuit is broken, and you will need to repair or replace it.

Step 3: Check the Oil Pressure Sensor

If the circuit is not the problem, the next step is to check the oil pressure sensor. The oil pressure sensor is responsible for sending a signal to the oil change lamp when the oil pressure is low. If the sensor is faulty, it may not send the signal, causing the warning light to fail. To check the sensor, use a multimeter to test the voltage at the sensor connector. If there is no voltage, the sensor is faulty, and you will need to replace it.

Step 4: Check the Wiring

If the sensor is not the problem, the next step is to check the wiring. The wiring may be damaged or broken, which can cause the circuit to fail. To check the wiring, use a multimeter to test the continuity of the wires. If there is no continuity, the wiring is broken, and you will need to repair or replace it.
