Check Engine Light Diagnostics
Whether navigating your weekday commute, running errands around town, or managing school pick-ups and drop-offs, there’s nothing quite like the stress of seeing the check engine light on your dashboard. The light is an immediate cause for concern because it signifies something’s wrong with your vehicle, but what’s the issue? Our experts at Loganville Ford can answer that question by running check engine light diagnostics. As a full-service automotive center, you can rely on our team to oversee everything your vehicle needs to run great. More importantly, we guarantee a new and rewarding service experience you won’t find anywhere else. So, how do we deliver?
Most customers dread bringing their vehicles in for service because it’s inconvenient and, more often than not, stressful. Unfortunately, dealerships do little to minimize that inconvenience. Service centers are notoriously busy, with a revolving door of people and a barrage of phone calls and noises that cultivate a high-stress environment. This cacophony adds to an already inconvenient experience, only worsened by a service team that doesn’t openly communicate what’s happening with your car and what you can expect.
Our customers deserve more; you deserve better, and we are honored to deliver. Our service team takes a personalized approach, listening attentively and responding to your needs. They operate with integrity and transparency, maintaining an open line of communication between you and the technicians working on your vehicle. Because of this, there are never any surprises regarding what your vehicle needs, the estimated repair costs, or the anticipated timeline. How else do we go above and beyond to improve your service experience? What could be the culprit behind that pesky check engine light? Let’s dive in and find out.
The Check Engine Light: What Does It Mean?
Think of the check engine light as your car’s way of communicating a red flag or an operating issue. Unlike the specificity of an oil life indicator, the check engine light is a generalized warning that something is wrong. It’s up to you to determine the issue, which is where our experts can help. Our technicians can run a check engine light diagnostic to determine the cause of the issue. The diagnostic test is straightforward and provides our technicians with a code that indicates what’s wrong and the steps to correct the problem. Now, the question is, what are the common issues associated with that light?
The Gas Cap: Is it Faulty or Loose?
What does the gas cap have to do with a check engine light? Despite the cap being nowhere near the engine, it’s part of your vehicle’s evaporative emissions system and is closely monitored. The system recirculates gasoline vapors from the gas tank to prevent them from reaching the air, which is where the gas cap plays a vital role. If the cap is loose or faulty, the system will detect a leak that can trigger the check engine light. When running diagnostics, our technicians can determine if it’s a direct issue with the gas cap. In some instances, the gas cap isn’t the concern. Instead, the problem is one of the components in the evaporative emissions system, like a fitting, connector, or hose.
Air and Oxygen Sensors: Are They Malfunctioning?
A check engine light can signify a malfunctioning air or oxygen sensor. The oxygen sensor is vital to your engine because it measures the amount of unburned oxygen in the exhaust to determine if the engine is running with the ideal ratio of air to fuel. If this sensor malfunctions, your engine will burn more fuel, forcing you to spend more money at the tank and heightening the risk of more extensive damage to parts like the catalytic converter.
Alternatively, the check engine light might indicate an issue with the mass airflow sensor. While the oxygen sensor monitors the oxygen level in the exhaust, the airflow sensor monitors the air entering the engine. The sensor determines how much air the engine needs to run efficiently and optimally, making it vital to how your engine performs. Unfortunately, the position of the airflow sensor makes it prone to picking up dirt and other debris that can signal the check engine light.
Faulty Spark Plugs
Our technicians will run a check engine light diagnostic to determine if the engine needs new spark plugs. Spark plugs play a vital role in the combustion process, which also means they’re prone to excessive wear and tear. Over time, spark plugs can fail and cause the engine to misfire. While you may not notice these issues immediately, the check engine light will alert you to misfires caused by a bad spark plug, a defective fuel injector, worn piston rings, or a bent valve.
