How to Fix B1386 Oil Level Lamp Circuit Short to Ground
If you’re experiencing the B1386 error code on your car, it means that there’s a problem with the oil level lamp circuit. This can be caused by a short to ground, which can be a frustrating issue to deal with. However, with the right tools and knowledge, you can fix this problem yourself and save money on costly repairs.
Step 1: Check the Wiring
The first step in fixing the B1386 error code is to check the wiring. Start by inspecting the wiring for any signs of damage or wear. Look for frayed wires, loose connections, or any other issues that could be causing the short to ground.
If you find any damaged wiring, you’ll need to replace it. This can be done by splicing in a new section of wire or replacing the entire wiring harness. Be sure to use the correct gauge wire and connectors for your car’s make and model.
Step 2: Check the Oil Level Sensor
If the wiring looks good, the next step is to check the oil level sensor. This sensor is responsible for sending a signal to the oil level lamp when the oil level is low. If the sensor is faulty, it can cause the B1386 error code.
To check the sensor, start by disconnecting the wiring harness. Then, use a multimeter to test the resistance of the sensor. The resistance should be within the manufacturer’s specifications. If it’s not, you’ll need to replace the sensor.
Step 3: Check the Oil Level Lamp
If the wiring and sensor are both in good condition, the next step is to check the oil level lamp itself. This lamp is responsible for alerting you when the oil level is low. If the lamp is faulty, it can cause the B1386 error code.
To check the lamp, start by disconnecting the wiring harness. Then, use a multimeter to test the resistance of the lamp. The resistance should be within the manufacturer’s specifications. If it’s not, you’ll need to replace the lamp.
Step 4: Clear the Error Code
Once you’ve fixed the issue causing the B1386 error code, you’ll need to clear the code from your car’s computer. This can be done using an OBD-II scanner. Simply connect the scanner to your car’s OBD-II port and follow the instructions to clear the code.
Fixing the B1386 error code can be a simple process if you know what to look for. By checking the wiring, oil level sensor, and oil level lamp, you can identify and fix the issue causing the short to ground. With a little bit of knowledge and some basic tools, you can save money on costly repairs and keep your car running smoothly.
