The B1260 code refers to a solar radiation sensor issue in a vehicle’s Electronic Automatic Temperature Control (EATC) system. This sensor is responsible for measuring the intensity of sunlight and adjusting the temperature accordingly.
Symptoms of the B1260 code may include inaccurate temperature readings, inconsistent climate control, or the inability to adjust the temperature based on sunlight levels.
Causes of this code can vary, but common reasons include a faulty solar radiation sensor, damaged wiring or connectors, or a malfunctioning EATC module.
To fix the B1260 code, start by inspecting the solar radiation sensor and its wiring for any visible damage. If no issues are found, use a diagnostic scan tool to reset the EATC system and clear the code.
If the problem persists, it may be necessary to replace the solar radiation sensor or the EATC module. Consulting a professional technician or referencing the vehicle’s repair manual can provide further guidance.
Code B1260: Fault in the Solar Radiation Sensor Circuit
What does it mean
The B1260 code indicates a fault in the solar radiation sensor circuit, commonly found in vehicles with Electronic Automatic Temperature Control (EATC) modules.
This code is triggered when the sensor does not function correctly, leading to inaccurate climate control readings.
To reset the code, the underlying issue must be addressed, such as a faulty sensor or poor electrical connections.
Professional diagnosis may be needed.
What are the symptoms
The symptoms of the B1260 code are the Engine Light or Service Engine Soon Warning Light turning on. It is important to address this code promptly to avoid potential issues. Ignoring the code can lead to more damage and costly repairs.
Common diagnostic errors with the B1260 code include mistakenly identifying the solar radiation sensor as faulty when the actual problem is with the wiring or the EATC module. It is crucial to thoroughly inspect the wiring and connectors for any damage or corrosion. It is also important to check for broken, bent, pushed out, or corroded connector pins.
What are the causes
Possible causes of the B1260 code include:
- A faulty solar radiation sensor
- A problem with the sensor’s wiring or connection
- A malfunctioning Electronic Automatic Temperature Control (EATC) module
- Other potential causes.
What Tools are Needed to diagnose
Here are three key tools that you will need to diagnose the B1260 code:
- OBD-II Scanner: This tool is necessary for accessing the onboard diagnostic system of the vehicle. It allows technicians to read and retrieve the trouble codes, including the B1260 code, stored in the system. The scanner provides valuable information about the specific issues affecting the solar radiation sensor and helps in pinpointing the exact cause of the problem.
- Multimeter: A multimeter is used to measure electrical values like voltage, resistance, and continuity. It is essential for checking the wiring harness and connectors of the solar radiation sensor. By testing the electrical connections and components, technicians can identify any open circuits, short circuits, or poor electrical connections that may be causing the B1260 code.
- Solar Radiation Sensor Tester: This specialized tool is designed specifically for testing the solar radiation sensor. It simulates different light conditions to evaluate the sensor’s response and accuracy. By analyzing the sensor’s performance, technicians can determine if it is functioning properly or if it needs to be replaced.
Having these diagnostic tools on hand ensures accurate and efficient diagnosis of the B1260 code, leading to effective repairs and resolving the issue with the solar radiation sensor.
How to fix Step by Step
Step 1: Check the solar radiation sensor for any faults.
Step 2: Inspect the sensor harness for open or shorted circuits.
Step 3: Ensure there are no poor electrical connections in the solar radiation sensor circuit.
Step 4: If the issue persists, check the electronic automatic temperature control (EATC) module for faults.
Step 5: Visually inspect the wiring harness and connectors for any damage.
Step 6: Look for broken, bent, pushed out, or corroded connector pins.
Step 7: These are common solutions to troubleshoot the B1260 code.
Step 8: It is important to note that the cost to diagnose the code may vary depending on the location, make and model of the vehicle, and engine type.
What are the Common Diagnosis Mistakes
One common mistake when diagnosing the B1260 code is not considering the possibility of poor electrical connections in the solar radiation sensor circuit. To avoid common diagnostic errors, you should follow these troubleshooting tips:
- Make sure that all electrical connections in the solar radiation sensor circuit are secure and free from corrosion.
- Check for any damaged or frayed wires in the circuit that could be causing a poor connection.
- Test the solar radiation sensor for proper functionality using a multimeter or by comparing readings to the manufacturer’s specifications.
What is the Repair Cost
The repair cost for a B1260 code varies based on location, vehicle make and model, and engine type. Labor rates typically range from $75 to $150 per hour.
Regular maintenance and inspections are essential to prevent the code from recurring. Checking the solar radiation sensor wiring harness and following the manufacturer’s recommended maintenance schedule can help ensure proper functioning.
Can I drive safely with this code?
Driving with the B1260 code may be unsafe. It indicates a malfunction in the solar radiation sensor, which can affect the vehicle’s climate control system.
Check wiring and connectors for damage, but it’s best to have a professional diagnose and fix the issue for safe driving conditions.
Wrapping Up
The B1260 code is associated with the solar radiation sensor in a vehicle’s EATC system. It may cause symptoms such as the illumination of the engine light.
The code can be diagnosed by visually inspecting the wiring harness and connectors for damage. It is recommended to seek professional assistance for accurate diagnosis and repair.
Overall, understanding the meaning, causes, and symptoms of the B1260 code can help individuals effectively address this issue in their vehicles.
