The most common reasons a 2014 Subaru BRZ has a check engine light are an emissions system component, a sensor, or a catalytic converter.
Get a professional diagnosis and avoid unnecessary 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.
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.
When faced with a check engine light on your 2014 Subaru BRZ, the first step is to assess the light's behavior; a steady light suggests a less urgent issue, while a blinking light indicates a serious problem that requires immediate attention. Next, utilize an OBD-II scanner to retrieve trouble codes from the vehicle's onboard computer, as these codes provide crucial insights into the underlying issues. If you lack a scanner, there are alternative methods to access these codes, though they may be more complicated. After obtaining the codes, research their meanings to identify potential problems, which could range from a loose gas cap to more intricate issues like a faulty oxygen sensor. Before delving into complex repairs, check for basic issues such as ensuring the gas cap is secure and inspecting battery connections for any visible damage. If the codes point to sensor-related problems, carefully examine the sensors and their wiring for signs of wear or corrosion, especially if you've driven in adverse weather conditions. Should the diagnostics become overwhelming or if you're uncertain about the next steps, consulting a professional at a Subaru service center is advisable, as they possess the expertise and tools necessary for accurate diagnosis and repair. By following this structured approach, you can effectively troubleshoot the check engine light and take informed steps toward resolving the issue.
When the check engine light illuminates in your 2014 Subaru BRZ, it can be a source of concern, but understanding the common issues can help you diagnose the problem effectively. One of the simplest culprits is a loose or improperly sealed gas cap; ensuring it is tightened until it clicks can often resolve the issue without further intervention. More complex problems may involve the vehicle's emissions system, particularly the oxygen sensor, which can fail and trigger the light. Additionally, worn spark plugs or faulty ignition coils are frequent offenders that can disrupt engine performance and illuminate the warning. Wiring issues can also lead to electrical faults that activate the check engine light, so inspecting the wiring for any visible damage is advisable. Furthermore, issues within the transmission, cooling system, or fuel system can contribute to this warning, necessitating a thorough check of these components. It's also crucial to monitor engine oil levels, as low oil or pressure problems, especially related to the camshaft gear in the FA20 engine, can lead to serious engine damage. Lastly, utilizing a compatible scanner to read the engine fault codes can provide specific insights into the underlying issues, allowing for a more targeted DIY repair approach. Regular maintenance and prompt attention to the check engine light can help prevent more severe and costly repairs down the line.

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.
When dealing with a check engine light in your 2014 Subaru BRZ, understanding the urgency of the situation is crucial for both safety and vehicle longevity. A blinking check engine light signals a critical issue, often related to severe engine misfires, which can lead to unburned fuel entering the exhaust system and potentially damaging the catalytic converter. This scenario necessitates immediate action; you should safely pull over and seek professional diagnosis and repair to avoid costly damage. Conversely, a solid check engine light indicates a non-emergency but still requires prompt attention. While you can continue driving, it’s wise to schedule a mechanic's appointment soon to diagnose the underlying issue, as neglecting it could result in diminished engine performance or further complications, such as damage to the oxygen sensor. Additionally, be mindful of other symptoms like poor acceleration or rough idling, which can signal the severity of the problem. Ultimately, addressing these warning signs promptly not only ensures your safety but also helps maintain the health of your vehicle, making it essential for any DIY enthusiast to stay vigilant and proactive.
