The most common reasons a 2024 Mitsubishi Eclipse Cross has a check engine light are an emissions system component, a sensor, or a catalytic converter.
  • Emissions System: A faulty emissions system component, such as an oxygen sensor or EGR valve, can lead to increased emissions and trigger the check engine light.
Proper diagnosis will determine the exact cause of your symptom, saving you money on unnecessary repairs. The diagnostic experts at RepairPal Certified shops have the right tools and experience to solve any symptom.

How much does it cost to fix a 2024 Mitsubishi Eclipse Cross has a check engine light?

Common Repairs

The total repair cost will vary based on the condition of your vehicle and the number of repairs needed to fix your symptom. Proper diagnosis will save you money by finding the exact repairs needed to fix your car right the first time.

A faulty oxygen sensor is one of the most common causes of a check engine light. Symptoms may include a decrease in fuel mileage, hesitation or misfiring from the engine, rough idling or even stalling. A faulty sensor may cause the vehicle to fail an emissions test.

Any time there is an emissions fault the check engine light will be displayed. The purpose of the check engine light is to inform the driver that an emission related fault has been found, and that there are on-board diagnostic (OBD) trouble codes stored in the powertrain or engine control module. Additionally, since the emissions systems are so intertwined into engine control and transmission control systems, symptoms may include nearly any sort of drivability concerns. This may include harsh shifting, failure to shift, hesitation on acceleration, jerking, engine failure to start or run, loss of power, or any number of other drivability issues.

Due to the nature of electrical systems on modern vehicles, the range of problems these can cause are nearly limitless. However, there is a way to categorize them in two ways. Permanent and intermittent problems. Permanent problems appear and remain. This may be the vehicle will not start, the radio does not work, or the door chime will not turn off among many, many others. These problems are more straight-forward to diagnose since they present themselves at all time. This means there will always be a fault to find. Intermittent electrical problems, however, can be difficult or impossible to locate, since they appear then disappear without warning. The best case scenario for an intermittent issue is when replicating the problem is easily accomplished and understood. This allows a technician to make an issue semi-permanent, allowing them to find the fault. Other issues that come and go without warning and cannot be replicated on demand must occur when the technician is servicing the vehicle, otherwise there is no problem to correct. It is most important to understand that electrical system faults always require inspection, and can include the vehicle working in any manner, or not working at all.

Like we noted in the last section, general diagnosis symptoms are the most vague of the bunch. There are several diagnostic spectrums, electrical diagnosis, drivability diagnostics, engine diagnostics, transmission diagnostics, and the list could continue for about 5 or 10 more spectrums of diagnostics. The most important take-away here, is that general diagnostics are diagnostics that have no other spectrum in which they fit, or the problem is unknown. This means that any vehicle left outside of a repair facility with the keys and an authorization to perform diagnosis will be diagnosed under the general diagnosis spectrum.

When the Check Engine Light comes on, you may experience engine performance issues such as poor acceleration, rough idling, or an engine that won't start. In some cases, no abnormal symptoms will be experienced. Other systems like the transmission or ABS can cause the Check Engine Light to illuminate and lights for those systems can come on at the same time. Similar lights may say "Check Engine Soon", "Malfunction Indicator Light" or just "Check". In rare case the engine can overheat.

What steps should I take to diagnose the check engine light on my 2024 Mitsubishi Eclipse Cross?

To effectively diagnose the check engine light on your 2024 Mitsubishi Eclipse Cross, start by checking for any additional warning lights on the dashboard, as these can provide clues about specific issues. Next, inspect the gas cap to ensure it is securely tightened, as a loose cap is a common and easily fixable cause of the check engine light. If the light persists, utilize an OBD-II scanner to connect to the vehicle's diagnostic port and retrieve any stored error codes. Carefully read and interpret these codes, as they will guide you in identifying the underlying problem. Research the meaning of the error codes using your vehicle's manual or reliable online resources to gain a better understanding of the issues at hand. Additionally, familiarize yourself with common problems associated with the Mitsubishi Eclipse Cross that could trigger the check engine light. If, after these steps, you are still unable to pinpoint the issue, it may be wise to consult a qualified mechanic for a comprehensive diagnosis and repair. By following this structured approach, you can efficiently address the check engine light and ensure your vehicle remains in optimal condition.

What are the common problems that could cause the check engine light to illuminate in a 2024 Mitsubishi Eclipse Cross?

When the check engine light comes on in a 2024 Mitsubishi Eclipse Cross, it can indicate several common problems that are often manageable for DIY enthusiasts. One of the first things to check is the gas cap; a loose or damaged cap can lead to fuel vapor leaks, triggering the light. Another frequent culprit is a faulty oxygen sensor, which can affect both fuel efficiency and emissions. If the catalytic converter is malfunctioning, it may also cause the light to illuminate, as this component is vital for reducing harmful emissions. Additionally, issues with spark plugs or ignition coils can lead to engine performance problems, resulting in the check engine light activation. The mass airflow sensor, responsible for measuring air intake, can also fail, disrupting the air-fuel mixture and triggering the warning. Engine misfires, often caused by faulty spark plugs or ignition coils, are another common reason for the light to turn on. Furthermore, a malfunctioning EGR valve can lead to increased emissions and trigger the light. Problems within the fuel system, such as a clogged fuel filter or failing fuel pump, can also be responsible. Lastly, various sensors, including the throttle position and coolant temperature sensors, may malfunction and illuminate the check engine light. Addressing these issues promptly is crucial to maintaining vehicle performance and preventing further damage, making it essential for DIYers to diagnose and resolve these common problems effectively.

How urgent is it to address the check engine light in a 2024 Mitsubishi Eclipse Cross?

When the check engine light illuminates in your 2024 Mitsubishi Eclipse Cross, it is essential to recognize the urgency of the situation. This warning indicator is not merely a nuisance; it signifies that there may be underlying issues with your vehicle's engine or emissions system that could compromise its performance and efficiency. Ignoring this alert can lead to escalating problems, including costly repairs or even a complete breakdown, which can leave you stranded and facing significant inconvenience. By addressing the check engine light promptly, you can identify and resolve any issues before they escalate, safeguarding your vehicle's health and ensuring a smooth driving experience. Therefore, it is highly recommended to have your vehicle inspected by a qualified mechanic or dealership as soon as the light comes on, allowing for timely intervention and the prevention of further damage. Prioritizing this action not only protects your investment but also enhances your safety on the road.
