How to Diagnose and Solve C1708 Right Rear Center Sensor Circuit Short to Vbat Issues

As a seasoned car expert, I understand the frustration that comes with encountering a C1708 Right Rear Center Sensor Circuit Short to Vbat issue. This problem can be a real headache, but don’t worry, I’m here to help you diagnose and solve it.

Understanding the C1708 Code

Firstly, it’s crucial to understand what the C1708 code means. This code indicates a problem with the right rear center sensor circuit in your vehicle. Specifically, it means there’s a short to the vehicle’s battery voltage (Vbat). This can cause various issues, including poor vehicle performance and increased fuel consumption.

Common Symptoms of C1708 Code

The symptoms of a C1708 code can vary, but some common signs include:

– **Check Engine Light**: This is usually the first sign that something is wrong. If your check engine light is on, it’s a good idea to get your vehicle checked out.

Now that we understand what the C1708 code means and its symptoms, let’s move on to diagnosing the problem.

Step 1: Use an OBD-II Scanner

The first step in diagnosing a C1708 code is to use an OBD-II scanner. This device can read the trouble codes stored in your vehicle’s computer and help identify the problem.

Step 2: Inspect the Sensor Circuit

Next, inspect the right rear center sensor circuit. Look for any signs of damage, such as frayed wires or loose connections. If you find any issues, they’ll need to be repaired.

Step 3: Check the Battery Voltage

Finally, check the battery voltage. If it’s too high, it could be causing the short in the sensor circuit.

Solving the C1708 Code

Once you’ve diagnosed the problem, it’s time to solve it. Here’s how:

Step 1: Repair or Replace Damaged Components

If you found any damaged components during your inspection, they’ll need to be repaired or replaced. This could involve replacing frayed wires or tightening loose connections.

Step 2: Adjust the Battery Voltage

If the battery voltage is too high, it will need to be adjusted. This can usually be done by a professional mechanic.

Step 3: Clear the Code

Once the problem has been fixed, use your OBD-II scanner to clear the C1708 code. If the code comes back, it means the problem hasn’t been fully resolved and further diagnostics may be needed.


Dealing with a C1708 Right Rear Center Sensor Circuit Short to Vbat issue can be challenging, but with the right knowledge and tools, it’s a problem you can solve. Remember, if you’re ever unsure about anything, it’s always best to consult with a professional mechanic.
