How to Fix B1259 Solar Radiation Sensor Circuit Open
If you own a car, you know how frustrating it can be when the check engine light comes on. One of the most common issues that can trigger this warning is the B1259 Solar Radiation Sensor Circuit Open. This problem can be caused by a variety of factors, including a faulty sensor or a damaged wire. In this article, we will guide you through the steps to fix this issue and get your car back on the road.
Step 1: Check the Sensor
The first thing you need to do is locate the solar radiation sensor. This sensor is usually located on the dashboard, near the windshield. Once you have located the sensor, check to see if it is damaged or dirty. If the sensor is dirty, clean it with a soft cloth. If it is damaged, you will need to replace it.
Step 2: Check the Wiring
If the sensor is not the problem, the next step is to check the wiring. Start by inspecting the wires for any signs of damage or wear. If you find any damaged wires, you will need to replace them. If the wires look fine, use a multimeter to check for continuity. If there is no continuity, you will need to repair or replace the wiring.
Step 3: Check the Fuse
If the sensor and wiring are both fine, the next step is to check the fuse. The solar radiation sensor circuit is usually protected by a fuse. Check the owner’s manual to locate the fuse box and find the fuse that corresponds to the solar radiation sensor circuit. If the fuse is blown, replace it with a new one.
Step 4: Reset the Check Engine Light
Once you have fixed the issue, you will need to reset the check engine light. You can do this by disconnecting the battery for a few minutes or by using an OBD-II scanner.
