The most common reasons a 2016 Chevrolet Trax 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 2016 Chevrolet Trax 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 are the initial diagnostic steps to take for a check engine light on a 2016 Chevrolet Trax?

When faced with a check engine light on your 2016 Chevrolet Trax, the first step is to check the gas cap, as a loose or missing cap can often trigger the warning. If the cap is secure, the next step involves using an OBD scanner to read the trouble codes from the engine control module, which will pinpoint the specific issue. Common culprits include a faulty oxygen sensor, a dirty Mass Airflow (MAF) sensor, or issues with spark plugs and ignition coils. Once you identify the problem, address it accordingly. After repairs, you can clear the check engine light by driving the vehicle, allowing the system to recognize the fix. Additionally, consider that the light may indicate broader issues related to the emission system, ignition, or engine timing, so keep these areas in mind during your assessment. Lastly, monitor the behavior of the check engine light; if it remains illuminated or fails to activate during startup, it may signal a more serious problem that requires professional attention. By following these steps, you can effectively diagnose and potentially resolve the check engine light issue on your Chevy Trax.

What are the common problems that could cause the check engine light to illuminate in a 2016 Chevrolet Trax?

When the check engine light comes on in your 2016 Chevrolet Trax, it can be concerning, but understanding the common problems associated with this warning can empower you to take action. One frequent culprit is a loose or damaged gas cap, which can disrupt the fuel system's pressure and trigger the light. Another common issue is a faulty oxygen sensor, which plays a crucial role in monitoring exhaust emissions and fuel efficiency. If the catalytic converter is failing or not functioning efficiently, it can also cause the check engine light to illuminate, indicating a need for attention. Additionally, problems with spark plugs or ignition coils can lead to misfires, resulting in the warning light activating. A malfunctioning mass airflow sensor can disrupt the air-fuel mixture, further contributing to the issue. Lastly, issues with the exhaust gas recirculation (EGR) valve can also trigger the check engine light, as it affects the vehicle's emissions control system. Addressing these problems promptly is essential to maintain your vehicle's performance and prevent further damage, making it wise to conduct a thorough inspection or consult a mechanic if the light remains on.

How urgent is it to address the check engine light in a 2016 Chevrolet Trax?

When the check engine light illuminates in your 2016 Chevrolet Trax, it is crucial to recognize the urgency of the situation. This warning light is not merely a nuisance; it signals potential issues within the engine or emissions system that could escalate into more severe problems if left unaddressed. Ignoring the check engine light can lead to costly repairs down the line, as minor issues can develop into major engine failures or safety hazards. By taking immediate action, such as having the vehicle diagnosed by a qualified mechanic, you can identify the root cause of the warning and prevent further damage. This proactive approach not only helps maintain the vehicle's performance and efficiency but also ensures your safety on the road. Therefore, addressing the check engine light promptly is essential for the reliability of your Chevrolet Trax and to avoid unexpected breakdowns.
