How to Diagnose and Solve C1175 Speed Wheel Sensor LR 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 nitty-gritty of diagnosing and solving the C1175 Speed Wheel Sensor LR Input Circuit Failure issue.

Understanding the C1175 Code

Before we dive into the solution, let’s first understand what the C1175 code means. This code is triggered when the Anti-lock Brake System (ABS) module detects a problem with the left rear wheel speed sensor. But what does this mean for your car? Well, it could lead to issues with your ABS system, which could affect your car’s braking efficiency.

Common Symptoms

How do you know if your car has a C1175 issue? Here are some common symptoms:

1. ABS warning light is on
2. Decreased braking efficiency
3. Unusual noises when braking

Diagnosing the C1175 Code

Now that we know what the C1175 code is and its symptoms, let’s move on to diagnosing the issue.

Tools You’ll Need

To diagnose this issue, you’ll need the following tools:

1. OBD-II scanner
2. Multimeter
3. Basic hand tools

Steps to Diagnose

1. Connect the OBD-II scanner to your car’s diagnostic port and read the trouble codes.
2. If the C1175 code is present, it indicates an issue with the left rear wheel speed sensor.
3. Use a multimeter to check the voltage at the wheel speed sensor. If the voltage is not within the manufacturer’s specifications, it indicates a problem with the sensor or the wiring.

Solving the C1175 Code

Once you’ve diagnosed the issue, it’s time to solve it.

Tools You’ll Need

To fix this issue, you’ll need the following tools:

1. New wheel speed sensor (if necessary)
2. Basic hand tools

Steps to Solve
