How to Fix B1306 Oil Level Switch Circuit Open
If you’re experiencing the B1306 error code on your car, it means that there’s an issue with the oil level switch 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 B1306 error code and get your car running smoothly again.
What is the B1306 Error Code?
The B1306 error code is a diagnostic trouble code that indicates an issue with the oil level switch circuit. This circuit is responsible for monitoring the oil level in your car’s engine and sending that information to the engine control module (ECM). When the ECM detects a problem with the oil level switch circuit, it will trigger the B1306 error code.
Step-by-Step Guide to Fixing the B1306 Error Code
Step 1: Check the Oil Level
The first thing you should do when you see the B1306 error code is to check the oil level in your car’s engine. Make sure that the oil level is within the recommended range. If the oil level is low, add more oil until it reaches the appropriate level.
Step 2: Inspect the Oil Level Switch
If the oil level is within the recommended range, the next step is to inspect the oil level switch. The oil level switch is located on the side of the engine block and is connected to the oil pan by a wire. Check the wire to make sure it’s not damaged or disconnected. If the wire is damaged or disconnected, repair or replace it as necessary.
Step 3: Test the Oil Level Switch
If the wire is in good condition, the next step is to test the oil level switch. To do this, you’ll need a multimeter. Set the multimeter to measure resistance and touch the probes to the terminals on the oil level switch. The multimeter should read a resistance of around 0 ohms. If the multimeter reads a different resistance, replace the oil level switch.
Step 4: Clear the Error Code
Once you’ve fixed the issue with the oil level switch circuit, you’ll need to clear the B1306 error code from the ECM. 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 clear the error code.
– Always wear gloves and safety glasses when working on your car’s engine.
– Make sure the engine is cool before you start working on it.
– Use a torque wrench to tighten bolts to the manufacturer’s specifications.
– Consult your car’s owner’s manual for specific instructions and torque specifications.
