Check Engine Light in Deer Creek, OK

Check Engine Light

When driving around Deer Creek, OK, the last thing any driver wants is an unexpected glow on their dashboard, particularly the dreaded check engine light. This warning light, also known as the malfunction indicator lamp (MIL), signals a range of issues, from minor to severe. Fortunately, Kennedy Tire & Auto is here to guide you through the maze of trouble codes and get you safely back on the road.

Read on to learn more about the check engine light’s function and the reasons it turns on. We’ll also help you out with immediate steps, repair and service solutions, and tips to prevent the light from turning on in the first place.

Understanding the Check Engine Light’s Function

The check engine light is a component of your car’s onboard diagnostic systems. When it illuminates, it’s alerting you to a problem detected within the car’s systems. Contrary to its name, this light isn’t limited to just engine issues. It can indicate problems in the emission control system, exhaust system, and more.

The exact issue is stored as a trouble code, which can be read with an OBD II scanner. This is a professional tool commonly used by auto repair shops, including us at Kennedy Tire & Auto.

So, how do I know what’s wrong with my engine light? An OBD II scanner retrieves these trouble codes, providing insight into the specific problem that triggered the check engine light. It’s a first step to pinpointing the cause.

Common Causes for the Check Engine Light to Illuminate

The check engine light doesn’t just indicate a single problem. A myriad of reasons can trigger the check engine light, some of which include:

Loose or Damaged Gas Cap: If not properly secured after refueling, it can allow fuel vapors to escape, potentially leading to reduced fuel efficiency and increased emissions. A simple tightening or replacement often solves the issue.

Oxygen Sensor Failure: This sensor monitors the unburned oxygen in the exhaust, playing a crucial role in regulating the fuel mixture. If faulty, it can reduce fuel economy and increase harmful emissions, making it essential to address promptly.

Faulty Catalytic Converter: The catalytic converter transforms harmful gases produced during combustion into less harmful emissions. A malfunctioning converter not only leads to increased pollutant emissions but can also affect overall vehicle performance.

Bad Spark Plugs or Wires: Essential for igniting the fuel-air mixture in the combustion chambers, worn-out or faulty spark plugs and wires can lead to engine misfires, reduced power, and decreased fuel efficiency.

Malfunctioning Mass Airflow Sensor: This sensor measures the volume of air entering the engine, helping regulate the fuel mixture. A faulty sensor can cause an imbalanced air-fuel mix, leading to stalling, reduced power, and increased emissions.

Immediate Steps When Your Check Engine Light Comes On

Is it fine to drive with a check engine light on? If the light is steady, it often signals a non-urgent issue. However, if the check engine light is flashing, it indicates a more serious problem, such as a misfire that can damage the catalytic converter. Here’s what to do:

  1. Stay calm. Panicking won’t help.
  2. Note other warning lights that may accompany the check engine light.
  3. If the check engine light is flashing, reduce speed, avoid heavy acceleration, and visit a repair shop immediately.
  4. For a steady light, plan a visit to Kennedy Tire & Auto soon to diagnose the issue.

Potential Repairs & Solutions

Once we’ve determined the cause of the check engine light, repairs can range from simple fixes like securing a loose gas cap to more intricate tasks such as addressing issues in the catalytic converter or exhaust system. Some potential solutions include:

Replacing a Malfunctioning Oxygen Sensor: The oxygen sensor measures unburned oxygen in the exhaust. When faulty, it affects fuel efficiency and emissions; replacing it ensures optimal engine performance.

Changing Worn-Out Spark Plugs or Wires: Essential for engine ignition, worn-out plugs or wires can cause misfires and rough idling. Regular replacements ensure smooth engine operations.

Repairing or Replacing a Faulty Catalytic Converter: This component reduces harmful emissions by converting toxic gases. A malfunctioning converter decreases engine performance, and timely attention prevents larger issues.

Cleaning or Replacing a Defective Mass Airflow Sensor: This sensor gauges the air volume entering the engine. When dirty or faulty, it disrupts the air-fuel balance; cleaning or replacing it restores optimal combustion.

Tightening or Replacing the Gas Cap: A loose or damaged cap lets fuel vapors escape, triggering the check engine light. Ensuring a tight seal or a replacement resolves this simple issue.

These are only some of the solutions to a check engine light. For more information, it is best to get a professional diagnosis done by our technicians here at Kennedy Tire & Auto in Deer Creek, OK.

The Importance of Timely Check Engine Light Service

Postponing service when your check engine light turned on might seem tempting, but it’s akin to ignoring a doctor’s advice. Immediate attention can prevent minor issues from ballooning into major repairs. Moreover, driving with a malfunctioning emissions system or a flashing check engine light can lead to reduced performance and damage to the environment.

Tips to Prevent Frequent Check Engine Light Triggers

The check engine light can be a pain to deal with. To reduce the chances of the check engine light surprising you, be sure to follow these tips :

  • Schedule regular maintenance for your vehicle.
  • Use quality fuel and oil to keep internal parts clean.
  • Ensure the gas cap is secured after refueling.
  • Regularly inspect spark plugs and replace them when worn out.
  • Stay updated with recalls related to your vehicle.

Our Customer Reviews

I had a dealer do a recall on my 2021 Ram 1500. They also give me a diagnosis on my brakes claiming the master cylinder needed to be changed and the brake lines needed to be flushed for about $1300. I took it to Kennedy and they said they quoted the same service for about $700. When they ran a full diagnostic of the brake system, they found the brake system was fine and called me. Minimal charge for the diagnostic service. I will always take my vehicles to Kennedy moving forward and recommend you should too.

Garrett Gill Dec 12, 2025

Great service! Got me in same day as I called for a rotation and balance

Jason Roberts Dec 12, 2025

Thank You for making everything right it was very much appreciated.

Brandon Wight Dec 12, 2025

My husband wanted to surprise me with new tires before the weather got bad. However, when he got home this evening my warning lights were on and 3 out of the 4 new tires he just purchased today were either low/flat!! This is ridiculous, he could have had a wreck on the way home because of this. Tried to call but everyone had already left for the day. Needless to say, my car is undriveable & we'll be calling them in the morning to see how they'll fix this issue. I will update this post later. UPDATE: The morning after my post a representative contacted my husband & had my car towed in to replace the TPMS sensors. Although, I completely appreciate the spontaneity, this was supposed to be replaced when we purchased the tires because we were already charged for the kit. Since this post, I got another flat due to a nail in my tire & they fixed & repaired it immediately for this customer service I have updated the stars from 1 to 4. Good customer service is hard to find especially in today's economy, with that said, I would recommend Kennedy.

Not only was it easy to get an appointment, but they were very polite. They identified and fixed the problem quickly while keeping me updated. Will definitely bring my business back to them. Update: I have been using them for a few years now and am still pleased with their service. I continue to use them not only due to the ease of scheduling appointments but they don't run up the bill.

Vickie Kahkesh Dec 12, 2025

Kennedy always keeps me informed and gives me options. One of the car dealerships tried to tell me I needed about $700 worth of brake jobs. Kennedy looked at it and said I was within proper wear and had 4 to 6 more oil changes before I really needed to do my brakes. You can trust Kennedy to be honest and not try to rip you off.

Took my car in for serivce, had a tire that was leaking air. They found 2 nails in the tire, fixed it, filled it and put it back on the car while I waited. This was the day of the internet outage so wasn't able to pay for the service. Called today to make the payment and they said none was needed. I'm amazed ... thank you so much.
