As a car owner, you’re likely no stranger to the ominous glow of the check engine light. It’s a warning sign that something’s amiss under the hood, and it can be a source of anxiety and uncertainty. But have you ever stopped to consider the role of your tires in triggering this light? Specifically, can low tire pressure cause the check engine light to come on? In this comprehensive guide, we’ll delve into the relationship between tire pressure and the check engine light, exploring the potential causes, symptoms, and consequences of low tire pressure on your vehicle.
The check engine light is a critical component of your vehicle’s onboard diagnostics system (OBD-II). It’s designed to alert you to potential problems with the engine, transmission, or other vital systems. However, the light can be triggered by a wide range of issues, from minor to major. In this article, we’ll focus on the connection between low tire pressure and the check engine light, examining the underlying causes and consequences of this common problem.
The Importance of Tire Pressure
Tire pressure is a critical aspect of vehicle maintenance, and it’s often overlooked by car owners. Proper tire pressure is essential for safe driving, fuel efficiency, and tire longevity. Underinflated tires can lead to a range of problems, including reduced traction, increased rolling resistance, and uneven tire wear. In extreme cases, low tire pressure can even cause a blowout, which can be catastrophic on the road.
So, how does tire pressure affect the check engine light? The answer lies in the way modern vehicles are designed. Most cars and trucks use a sophisticated tire pressure monitoring system (TPMS) to monitor tire pressure and alert the driver to any issues. If the TPMS detects low tire pressure, it can trigger the check engine light to come on, even if there’s no other problem with the engine or transmission.
The Relationship Between Low Tire Pressure and the Check Engine Light
So, can low tire pressure cause the check engine light to come on? The answer is yes. When tire pressure is low, the TPMS can detect the issue and trigger the check engine light. This is because the TPMS is designed to monitor tire pressure and alert the driver to any problems. In some cases, the check engine light may come on even if there’s no other issue with the vehicle.

But why does the check engine light come on in response to low tire pressure? The answer lies in the way the TPMS communicates with the vehicle’s onboard computer. When the TPMS detects low tire pressure, it sends a signal to the onboard computer, which then triggers the check engine light to come on. This is a safety feature designed to alert the driver to a potential problem with the vehicle.
Causes of Low Tire Pressure
So, why do tires lose pressure in the first place? There are several potential causes, including:
- Tire damage: Punctures, cuts, or other damage to the tire can cause air to leak out, leading to low tire pressure.
- Worn-out valve stems: Over time, the valve stems on your tires can wear out, allowing air to escape and causing low tire pressure.
- Tire aging: As tires age, they can become more prone to air leaks, leading to low tire pressure.
- Incorrect tire inflation: Failing to properly inflate your tires can cause them to lose pressure over time.
- Temperature changes: Extreme temperatures can cause tire pressure to fluctuate, leading to low tire pressure.
Consequences of Low Tire Pressure
The consequences of low tire pressure can be severe, including:
- Reduced traction: Underinflated tires can reduce traction, making it more difficult to stop or turn.
- Increased rolling resistance: Low tire pressure can increase rolling resistance, leading to reduced fuel efficiency and increased wear on the tires.
- Uneven tire wear: Underinflated tires can cause uneven tire wear, leading to reduced tire life and increased maintenance costs.
- Blowouts: In extreme cases, low tire pressure can cause a blowout, which can be catastrophic on the road.
Checking and Maintaining Tire Pressure
So, how can you check and maintain proper tire pressure? Here are some tips:
- Check tire pressure regularly: Check tire pressure at least once a month, and before long trips.
- Use a tire pressure gauge: Invest in a good-quality tire pressure gauge to ensure accurate readings.
- Inflate tires to the recommended pressure: Check your owner’s manual for the recommended tire pressure for your vehicle.
- Monitor tire pressure changes: Keep an eye on tire pressure changes over time, and adjust as needed.
Recap
In this article, we’ve explored the relationship between low tire pressure and the check engine light. We’ve examined the causes and consequences of low tire pressure, and provided tips for checking and maintaining proper tire pressure. By understanding the importance of tire pressure and taking steps to maintain proper inflation, you can help prevent low tire pressure and ensure safe, efficient driving.
