Troubleshooting and Fixing the Right Side Wheel Sensor Issue in a 2017 Ram 2500

Have you been experiencing trouble with the right side wheel sensor in your 2017 Ram 2500? You're not alone. Many owners of this truck model have encountered this frustrating issue that affects the ABS system and causes the ABS warning light to come on. In this article, we'll guide you through the troubleshooting and fixing process to help you get your ABS system back in perfect working order.

Introduction

The ABS (Anti-lock Braking System) plays a crucial role in ensuring vehicle stability and safety. One component of this system is the wheel sensor, which detects the rotational speed of each wheel. If the wheel sensor on the right side malfunctions or fails to communicate, it can lead to a range of issues, including incorrect speed readings, ABS system failure, and the illumination of the ABS warning light on the dashboard.

Symptoms of the Right Side Wheel Sensor Issue

Before we dive into the troubleshooting process, let's take a look at some common symptoms that indicate a problem with the right side wheel sensor:

1. Illumination of the ABS warning light: When the ABS warning light comes on, it is a clear indication that there is a fault in the ABS system. This can be caused by a malfunctioning wheel sensor.

2. Erratic ABS behavior: If you notice that the ABS system is activating unexpectedly, such as when driving on dry pavement or during normal braking, it may be due to a faulty wheel sensor.

3. Inaccurate speedometer readings: A malfunctioning wheel sensor can cause incorrect speed readings on the speedometer. If you notice that the speedometer is not displaying the correct speed, it might be related to the right side wheel sensor issue.

Replacement of the Wheel Sensor

The first step in troubleshooting the right side wheel sensor issue is to replace the sensor itself. Start by locating the wheel sensor on the right side of the vehicle. Depending on the specific model and year of your Ram 2500, the sensor may be located on the front or rear wheel. Consult your vehicle's manual or a trusted mechanic to determine the exact location.

Once you've located the sensor, remove the electrical connector and unscrew the sensor using an appropriate tool. Replace the old sensor with a new one, ensuring a secure fit. It is recommended to use a factory mopar sensor for optimal compatibility and performance.

After replacing the sensor, reattach the electrical connector and proceed to test the ABS system to see if the issue has been resolved. If the problem persists, continue troubleshooting for a potential wiring issue.

Testing for a Wiring Issue

If replacing the wheel sensor did not fix the issue, there may be a problem with the wiring between the sensor and the ABS control module. To test for a wiring issue, you can perform a simple jumper wire test using a reliable wiring diagram.

Start by disconnecting the electrical connector from the right side wheel sensor. Take a jumper wire and connect it from the right side sensor to the corresponding harness on the left side. This will bypass the wiring and help determine if the issue lies with the sensor or the wiring itself.

Once the jumper wire is connected, start your vehicle and use a diagnostic tool, such as alpha obd, to check if the ABS system recognizes the jumpered wheel sensor and displays the correct speed readings. If the ABS system functions properly with the jumper wire, it indicates a wiring issue rather than a faulty sensor.

Troubleshooting the Junction Block

If the jumper wire test confirmed a wiring issue, the next step is to investigate the junction block. The junction block is a connector that links the ABS control module with the wheel sensors. It is located under the hood of your Ram 2500, typically near the ABS control module.

Inspect the junction block for any signs of damage or loose connections. Pay close attention to the connectors and pins inside the block. If any pins or connectors appear loose or damaged, it could be the source of the problem.

Identifying the Loose Connector

After careful inspection of the junction block, you might identify a loose connector as the culprit behind the right side wheel sensor issue. To confirm this, you can gently pull on the connector to see if it moves or comes off easily. A loose connector can result in intermittent communication between the sensor and the ABS control module, leading to the ABS warning light coming on.

If you determine that the loose connector is causing the issue, proceed with the necessary steps to fix it.

Resolving the Loose Connector Issue

To fix the loose connector issue in the junction block, follow these steps:

1. Carefully remove the plastic cover of the junction block using a screwdriver. Be cautious not to damage any surrounding components.

2. Locate the loose connector within the junction block. It should be visibly loose or not making a good contact with the corresponding pin.

3. Use a small prick pin punch to release the mechanism holding the wire in place. Once released, gently pull out the wire from the connector.

4. Using a punch or any suitable tool, tighten the fitting of the loose connector by pushing it in slightly. This will ensure a solid connection with the corresponding pin.

5. Once the fitting is tightened, carefully slide the wire back into the connector until it clicks into place. Ensure that it is securely attached and making a good contact.

Confirming the Fix

After resolving the loose connector issue, it is essential to confirm if the problem has been resolved. Reassemble the junction block, ensuring all components are securely in place. Put everything back together in the reverse order of the disassembly process.

Turn the key on and let everything cycle. Check if the ABS warning light remains off. If the light stays off, it indicates a successful fix for the right side wheel sensor issue.

Putting everything back together

Now that the issue is resolved, you can proceed with putting everything back together. Carefully reconnect any disconnected plugs, ensuring a secure fit. Replace any removed covers, caps, or fasteners, following the correct placement and alignment.

If you had to remove any zip ties during the troubleshooting process, make sure to replace them in their original positions to secure the wiring and connectors.

Lastly, reattach the wheel, making sure it is properly tightened and aligned. Double-check all connections and fasteners before taking your Ram 2500 for a test drive.

Conclusion

Troubleshooting and fixing the right side wheel sensor issue in your 2017 Ram 2500 can be a challenging task. However, by following the steps outlined in this guide, you can diagnose the problem accurately and take the necessary actions to fix it.

Remember to prioritize safety throughout the process and consult a professional mechanic if you encounter any difficulties or doubts. With a little patience and determination, you'll be able to restore your ABS system to full functionality and enjoy a smoother driving experience once again.
