How to Diagnose and Solve C1117 RPM Input Circuit Failure Issues

Introduction

Are you a car enthusiast who loves to get your hands dirty? Or perhaps you’re a DIYer who enjoys the satisfaction of fixing things yourself? If so, you’re in the right place. Today, we’re going to delve into the world of car diagnostics, specifically focusing on the C1117 RPM Input Circuit Failure issue. This is a common problem that can cause your vehicle to behave erratically, but don’t worry, we’ve got you covered.

Understanding C1117 RPM Input Circuit Failure

Before we dive into the solution, let’s first understand what the C1117 RPM Input Circuit Failure is. This error code is typically associated with the Anti-lock Braking System (ABS) of your vehicle. It indicates a malfunction in the RPM input circuit, which can lead to issues with your vehicle’s speed sensor, causing your car to behave unpredictably.

Signs of C1117 RPM Input Circuit Failure

How do you know if your vehicle is suffering from this issue? Here are some common signs:

1. The ABS warning light is on.
2. Your vehicle’s speedometer is not working correctly.
3. Your vehicle is not shifting gears properly.
4. You experience a decrease in fuel efficiency.

Diagnosing C1117 RPM Input Circuit Failure

Now that we know what to look for, let’s move on to diagnosing the problem.

Step 1: Use an OBD-II Scanner

The first step in diagnosing this issue is to use an OBD-II scanner. This device can read the error codes from your vehicle’s computer system and help you identify the problem.

Step 2: Check the ABS Sensor

If the scanner shows a C1117 error code, the next step is to check the ABS sensor. This sensor is responsible for monitoring the rotational speed of your vehicle’s wheels. If it’s faulty, it could be the cause of the problem.

Step 3: Inspect the Wiring

The wiring connected to the ABS sensor should also be inspected. Look for any signs of damage, such as fraying or corrosion.

Solving C1117 RPM Input Circuit Failure

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

Step 1: Replace the ABS Sensor

If the ABS sensor is faulty, it will need to be replaced. This is a relatively straightforward process that can be done with a few basic tools.

Step 2: Repair or Replace Damaged Wiring

If the wiring is damaged, it will need to be repaired or replaced. This can be a bit more complex, so if you’re not comfortable doing it yourself, it may be best to take your vehicle to a professional.

Step 3: Clear the Error Code

Once the issue has been resolved, you’ll need to clear the error code from your vehicle’s computer system. This can be done using the OBD-II scanner.

Conclusion

Dealing with a C1117 RPM Input Circuit Failure issue can be a bit daunting, but with a little knowledge and some DIY spirit, it’s a problem that can be tackled head-on. Remember, if you’re ever in doubt, it’s always best to consult with a professional. Happy fixing!
