Can TPMS Cause Check Engine Light Issues?

TPMS and the Check Engine Light: The Connection

The Tire Pressure Monitoring System (TPMS) is a crucial component in modern vehicles, designed to alert drivers when tire pressure is too low. However, many drivers wonder if issues with the TPMS can trigger the check engine light. This is a valid concern, as dashboard lights can indicate a range of problems, and knowing the relationship between these systems can save you time and money.

Can TPMS Cause Check Engine Light?

Yes, the TPMS can indeed cause the check engine light to illuminate. While the TPMS has its own dedicated warning light, certain malfunctions or failures within the system can lead to the check engine light being triggered. Here are some scenarios where this can happen:

• Faulty TPMS sensors: If the sensors are malfunctioning, they may send incorrect data to the Engine Control Unit (ECU), which can trigger the check engine light.


• Low tire pressure: While the TPMS light will typically come on first, if the issue persists, it can lead to other engine performance issues that may trigger the check engine light.


• Wiring issues: Damaged or corroded wiring related to the TPMS can cause electrical faults that the ECU detects, resulting in the check engine light being activated.

Common TPMS-Related Issues

When dealing with TPMS-related problems, it’s essential to be aware of the common issues that can arise. Here’s a quick rundown:

1. Sensor Failure: Sensors can wear out over time, leading to inaccurate readings.


2. Battery Issues: The batteries in TPMS sensors have a limited lifespan and can fail, causing the system to malfunction.


3. Improper Installation: If tires are replaced or rotated without properly resetting the TPMS, it can lead to warning lights.

Table of TPMS Issues and Their Impact on Check Engine Light

TPMS Issue	Symptoms	Potential Impact on Check Engine Light
Faulty TPMS Sensor	Inaccurate tire pressure readings	Can trigger check engine light due to data errors
Low Tire Pressure	TPMS light on, poor handling	May lead to engine performance issues
Wiring Issues	Intermittent warning lights	Can cause electrical faults detected by ECU
Battery Failure	TPMS light on, sensor not responding	May trigger check engine light if ECU detects sensor failure
Improper Reset	TPMS light remains on after tire change	Can confuse ECU, potentially triggering check engine light

What to Do if Your Check Engine Light Comes On

If your check engine light activates, it’s essential to take it seriously. Here’s a straightforward approach:

• Check for other warning lights: If the TPMS light is also on, it may indicate a tire issue.


• Inspect tire pressure: Use a tire gauge to ensure all tires are properly inflated.


• Scan for error codes: A diagnostic scan tool can help identify the specific issue causing the check engine light.


• Consult a mechanic: If you’re unsure, getting a professional opinion can save you from further complications.

Understanding the relationship between the TPMS and the check engine light can help you address potential issues before they escalate. Stay vigilant and proactive with your vehicle maintenance to keep everything running smoothly.

Facts About TPMS and the Check Engine Light

Understanding the relationship between the Tire Pressure Monitoring System (TPMS) and the check engine light is essential for vehicle maintenance. Here are some facts based on statistical data and authoritative sources.

TPMS Functionality and Statistics

1. TPMS System Overview

• TPMS became mandatory in the United States for all passenger vehicles manufactured after 2007.


• According to the National Highway Traffic Safety Administration (NHTSA), TPMS has been shown to reduce the risk of tire-related crashes by approximately 50%.

2. Common Issues Leading to Check Engine Light

1. Research from the Automotive Service Association indicates that around 30% of vehicles with a malfunctioning TPMS will also have the check engine light activated.


2. A study conducted by the Tire Industry Association found that 75% of drivers ignore warning lights, including the check engine light, which can lead to more severe vehicle issues.

Reliability Ratings and Sensor Performance

3. Sensor Lifespan

• According to industry standards, TPMS sensors typically have a lifespan of 5 to 10 years, depending on usage and environmental conditions.


• Data from the Tire Pressure Monitoring System Manufacturers Association shows that sensor failure is one of the leading causes of TPMS-related check engine lights.

4. Impact of Low Tire Pressure

1. The NHTSA reports that under-inflated tires can reduce fuel efficiency by up to 3%, potentially leading to engine performance issues that trigger the check engine light.


2. Studies indicate that driving on under-inflated tires increases tire wear, which can lead to further complications in the vehicle’s systems, including the ECU.

Diagnostic Insights

5. Diagnostic Trouble Codes (DTCs)

• When the check engine light is triggered due to TPMS issues, it often generates specific DTCs related to tire pressure sensors or system malfunctions.


• According to the Society of Automotive Engineers, many vehicles will log multiple codes when there is a TPMS failure, which can complicate diagnostics.

6. Importance of Regular Maintenance

1. Regular tire maintenance can prevent TPMS-related check engine lights. The Rubber Manufacturers Association recommends checking tire pressure monthly.


2. Failure to maintain proper tire pressure can lead to increased wear on the TPMS sensors, leading to premature failure and potential check engine light activation.

These facts highlight the significant connection between the TPMS and the check engine light, emphasizing the importance of maintaining both systems for optimal vehicle performance and safety.

Opinions of Vehicle Owners on TPMS and Check Engine Light
