Rough idling, lack of power, engine oil leaks, engine burning oil, and illumination of the check engine light are all possible if the PCV valve has clogged. If the check engine light comes on, the on-board diagnostics (OBD) trouble codes will most likely relate to manifold vacuum, air and fuel mixture, PCV system, mass airflow sensor readings, and exhaust and emissions readings. These are all affected in the event the PCV valve is clogged, is stuck fully open, or is stuck fully closed, however, if the valve is stuck fully open, the engine oil seals are not in danger of overpressure.
A bad valve cover gasket will result in an oil leak. You may notice oil under the car or on other parts under the hood. You might also notice a burning smell while driving.

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 diagnosing a vacuum leak in a 2015 Dodge Dart, it's essential to adopt a systematic approach that begins with the simplest methods before progressing to more complex diagnostics. Start with a thorough visual inspection of the vacuum hoses and connections, looking for any signs of wear, such as cracks or loose fittings. Next, listen for any hissing sounds while the engine is running, as these can be telltale signs of a leak. If these initial checks do not reveal the issue, utilize a vacuum gauge to measure the vacuum levels at idle and during acceleration; abnormal readings can indicate a leak. For a more hands-on approach, perform a spray test using carburetor cleaner or propane around suspected areas, observing any changes in engine RPM that suggest a leak. If necessary, a smoke test can be conducted to visually identify leaks, as smoke will escape from any compromised areas. Finally, using an OBD-II scanner to check for diagnostic trouble codes can provide additional insights into the vacuum system's health. By following this structured diagnostic approach, you can effectively pinpoint and address vacuum leaks in your vehicle.
When diagnosing a vacuum leak in your 2015 Dodge Dart, it's essential to understand the common problems that can arise. One of the primary culprits is worn-out hoses, which can develop cracks or holes over time, allowing air to escape and disrupt the engine's performance. Additionally, a faulty intake manifold gasket can lead to significant leaks, as can loose connections between vacuum hoses and fittings. It's also worth checking the brake booster, as a damaged unit can create a vacuum leak that affects braking efficiency. Symptoms of a vacuum leak are often noticeable; you may experience a rough idle, poor acceleration, or even a hissing noise emanating from the engine bay. Furthermore, the check engine light may illuminate, signaling an issue that requires attention. If you notice that your brake pedal feels unusually hard, this could indicate a problem with the brake booster due to a vacuum leak. By being aware of these common causes and symptoms, you can take proactive steps to diagnose and resolve any vacuum leak issues, ensuring your Dodge Dart runs smoothly and efficiently.
Addressing a vacuum leak in your 2015 Dodge Dart is not just a matter of convenience; it is a critical maintenance task that demands immediate attention. A vacuum leak can severely compromise engine performance, leading to symptoms such as rough idling, stalling, and a noticeable drop in fuel efficiency. These issues not only affect your driving experience but can also escalate into more serious problems if left unresolved. For instance, prolonged neglect of a vacuum leak can result in damage to vital components like the oxygen sensors and catalytic converter, which are essential for your vehicle's emissions control and overall functionality. Additionally, a vacuum leak may trigger the check engine light, signaling that your vehicle requires urgent diagnostics. By addressing the leak promptly, you can prevent further complications, ensuring that your engine operates smoothly and efficiently while safeguarding against costly repairs down the line. Therefore, it is crucial to prioritize the repair of a vacuum leak to maintain the performance and longevity of your Dodge Dart.
