Code B2795 Mercury Description
The B2795 diagnostic trouble code for Mercury vehicles indicates a problem with the solar radiation sensor circuit, specifically a short to ground. The solar radiation sensor is a crucial component that measures the intensity of sunlight and helps the vehicle's climate control system adjust the interior temperature accordingly. When the sensor circuit detects a short to ground, it means that there is an unintended connection between the sensor circuit and the vehicle's ground, causing inaccurate readings or a complete failure of the sensor.
Common Causes of B2795 Mercury
- Wiring or connector damage leading to a short to ground.
- Corrosion or moisture intrusion in the sensor circuit.
- Faulty solar radiation sensor.
- Electrical issues in the climate control system.
- Vehicle collision or impact causing damage to the sensor circuit.
Symptoms of B2795 Mercury
- Inaccurate temperature regulation by the climate control system.
- Automatic headlights or windshield wipers not functioning correctly.
- Dashboard warning light related to the solar radiation sensor.
- Interior temperature fluctuations based on sunlight intensity.
How to Fix B2795 Mercury
- Begin by conducting a visual inspection of the solar radiation sensor circuit, looking for any obvious signs of damage or corrosion.
- Use a multimeter to test the continuity of the sensor circuit and identify the location of the short to ground.
- Repair or replace any damaged wiring or connectors in the sensor circuit.
- Test the solar radiation sensor itself for proper functionality and replace if necessary.
- Clear the diagnostic trouble code from the vehicle's system and perform a test drive to ensure the issue has been resolved.
Cost to Fix B2795 Mercury
The typical repair costs for addressing a solar radiation sensor circuit short to ground issue can range from $150 to $400, including parts and labor. However, the specific diagnosis time and labor rates at auto repair shops can vary based on factors such as location, vehicle make and model, and engine type. It's advisable to check local rates for a more precise estimate. Keep in mind that rates in metropolitan areas or at dealerships may be higher, while independent shops often charge less.
