Check Engine Light After Tire Change: Troubleshooting Tips

If your check engine light comes on immediately after a tire change, it is likely related to the change. It could be due to a damaged ABS sensor or low tire pressure.

However, it is recommended to have a scan tool plugged into the diagnostic port to read the codes and determine the exact cause.

Causes Of Check Engine Light After Tire Change

After getting new tires installed, it can be quite frustrating to see the check engine light illuminate on your dashboard. This unexpected occurrence can leave you puzzled, wondering what could have possibly triggered the warning light. In many cases, the causes of a check engine light after a tire change can be attributed to specific factors such as low tire pressure or damaged ABS sensors or speed sensors. Understanding these causes can help you determine the appropriate course of action to resolve the issue and ensure your vehicle’s optimal performance.

Impact Of Low Tire Pressure

One of the common culprits behind a check engine light after a tire change is low tire pressure. If your vehicle has a malfunctioning indicator lamp, it will detect the decrease in tire pressure and trigger the check engine light to illuminate. This is particularly common in newer models that have a Tire Pressure Monitoring System (TPMS). As soon as you notice the check engine light, it’s crucial to check your tire pressure. Simply inflate or adjust the tire pressure to the recommended level, and the check engine light should turn off.

Damaged Abs Sensor Or Speed Sensors

In certain cases, a check engine light after a tire change can be a result of damaged ABS sensors or speed sensors. This scenario is more common in All-Wheel Drive (AWD) vehicles. When these sensors get damaged during tire rotations or replacement, they can trigger the check engine light. To diagnose this issue accurately, it is essential to connect a scan tool to the diagnostic port and read the error codes. This will help identify the specific sensor that requires repair or replacement. Consulting a professional technician will ensure the proper maintenance and restore the normal functioning of your vehicle.

Troubleshooting Tips

If your check engine light comes on after a tire change, it could be due to a damaged sensor or low tire pressure. Get a diagnostic scan to identify the issue and address it promptly to turn off the light.

Regular tire maintenance can prevent this from reoccurring.

Checking Tire Pressure

One of the first things to check if your check engine light comes on after a tire change is the tire pressure. Low tire pressure can often trigger the check engine light in modern vehicles equipped with TPMS (Tire Pressure Monitoring System). To ensure accurate tire pressure readings, use a reliable tire pressure gauge and refer to your vehicle’s manual for the recommended tire pressure levels. If the pressure is below the recommended range, inflate the tires accordingly. However, keep in mind that not all vehicles have a malfunctioning indicator lamp for low tire pressure detection.

Diagnostic Scan Tool And Reading Codes

If checking the tire pressure did not resolve the issue, the next step is to use a diagnostic scan tool to read the codes. Many auto parts stores or shops offer code reading services for free. Simply plug the diagnostic scan tool into the diagnostic port of your vehicle, typically located under the dashboard. The tool will retrieve error codes stored in the vehicle’s computer system, which can help pinpoint the source of the check engine light. Make note of any codes displayed and refer to the vehicle-specific code definitions to determine the necessary repairs or troubleshooting steps.

It’s important to note that certain tire-related issues, such as damaged ABS sensors or tire pressure sensor malfunctions, can trigger the check engine light. In such cases, professional assistance may be required to diagnose and resolve the problem.

Remember, regular maintenance and care for your vehicle, including checking tire pressure and addressing any detected issues promptly, can help prevent unnecessary check engine light illumination after a tire change.

Debunking Myths

After a tire change, a check engine light may illuminate due to low tire pressure or damaged sensors. It is essential to address tire issues promptly to avoid triggering the light. Consider getting a diagnostic scan to identify the specific cause and ensure proper maintenance.

Misconceptions About Alignment And Engine Light

One common misconception after a tire change is the belief that a misaligned wheel can trigger the check engine light. However, in reality, the alignment of the tires does not directly influence the activation of the check engine light. It’s essential to understand that while wheel alignment is crucial for vehicle performance and tire longevity, it does not have a direct impact on the engine’s operation or the activation of the check engine light.

The Role Of Tire Sensors

Vehicle tires are equipped with tire pressure monitoring systems (TPMS) sensors that detect changes in tire pressure and alert the driver. These sensors can indeed trigger the check engine light if the tire pressure becomes critically low. In modern vehicles, the TPMS is responsible for monitoring tire pressure, and an abnormal reading may result in the illumination of the check engine light. It’s important to note that the check engine light in this scenario is directly related to the tire sensors rather than the engine’s operation.

Frequently Asked Questions Of Check Engine Light After Tire Change

Can Tires Make A Check Engine Light Come On?

Yes, low tire pressure can trigger the check engine light on newer car models. Maintain proper tire pressure to turn off the light.

Why Does My Engine Light Come On After Tire Rotation?

After a tire rotation, the engine light may come on due to damaged ABS sensors or low tire pressure. Use a scan tool to read the codes and determine the exact cause. It is important to tend to your tires and repair any issues to turn off the engine light.

Can A Tire Sensor Cause Engine Light?

In some cars, low tire pressure can cause the check engine light to come on. This is because many modern vehicles have a tire pressure monitoring system (TPMS) that detects low tire pressure. However, it depends on the vehicle model.

Simply check and adjust your tire pressure as needed, and the check engine light should turn off.

Can Wheel Alignment Cause Check Engine Light?

No, wheel alignment cannot cause the check engine light. Low tire pressure or damaged ABS sensors may trigger it. Regular car maintenance can help prevent such issues.

Conclusion

After a tire change, it’s important to address any potential triggers for the check engine light. Whether it’s low tire pressure or damaged sensors, a thorough inspection is crucial. Always consult a professional to diagnose and resolve any issues. Taking care of your tires can prevent unnecessary alarms.

Stay vigilant and keep your ride in top shape.
