Modern vehicles often include maintenance codes in their driver information center, which differ from the Check Engine Light. These maintenance codes indicate required services based on various factors:
These maintenance codes help ensure your vehicle receives timely care, optimizing performance and longevity. Unlike older systems that relied solely on mileage and time, modern systems consider a range of factors to indicate when service is needed.
CONTACT one of our team members to discuss the maintenance schedule and make plans for your specific vehicle.
If your Check Engine Light turns on and off intermittently, it can be challenging to diagnose. These faults might occur seasonally, with mileage, or due to specific driving conditions. Intermittent issues can be both frustrating and difficult to pinpoint without proper diagnostics.

What should I do when the Check Engine Light comes on?
When the Check Engine Light illuminates, you should schedule an appointment to have the diagnostic trouble codes (DTCs) retrieved and analyzed. This will help identify the underlying issue and determine whether immediate repairs are necessary or if they can be scheduled around upcoming maintenance needs.
How serious are Diagnostic Trouble Codes?
DTCs can indicate a range of issues from minor, non-critical problems to more severe faults. Some codes may relate to emissions components that affect environmental compliance but do not impact the vehicle’s safety or drivability. Others may indicate more urgent issues that require immediate attention. Accurate diagnosis is essential to determine the severity and appropriate response.
Can I drive my vehicle if the Check Engine Light is on?
It depends on the nature of the issue. If the CEL is accompanied by other symptoms such as rough running, loss of power, or unusual noises, it’s best to have the vehicle inspected immediately. For some emissions-related codes that do not affect drivability, you might be able to drive temporarily but should schedule a diagnostic as soon as possible to avoid further complications. If the light is on and flashing, it is necessary to pull over as quickly and safely as possible. This indicates that the vehicle has a misfire that is bad enough to damage the catalytic converter and can result in more costly repairs.
What causes intermittent Check Engine Light issues?
Intermittent Check Engine Light issues can be caused by several factors, including loose or damaged connectors, failing sensors, or issues that only occur under specific conditions. These problems can be challenging to diagnose, requiring advanced tools and diagnostic techniques to identify and resolve.
How do maintenance service codes differ from Check Engine Light codes?
Maintenance service codes are designed to indicate when scheduled maintenance is due based on various factors, including time, mileage, and driving patterns. They are separate from Check Engine Light codes, which signal potential issues with engine or emission systems. Maintenance codes help you keep your vehicle in optimal condition, while CEL codes address specific mechanical or electronic faults.
