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.
To effectively diagnose a vacuum leak in your 2016 Mazda CX-5, start with a thorough visual inspection of the vacuum hoses and connections. Look for any signs of wear, such as cracks or loose fittings, which are common culprits for leaks. Next, listen for any hissing sounds while the engine is running, as these can indicate escaping air. If you suspect a leak, using a vacuum gauge can provide valuable insights; connect it to the intake manifold and observe the readings at idle and during revs—any significant fluctuations may point to a leak. For a more hands-on approach, perform a spray test by applying carburetor cleaner or propane around the suspected areas; a change in engine RPM will confirm the presence of a leak. If you want to be more thorough, consider conducting a smoke test, which visually reveals leaks by introducing smoke into the intake system. Lastly, if your check engine light is illuminated, utilize an OBD-II scanner to retrieve any trouble codes that may relate to the vacuum system. By following these steps in a systematic manner, you can efficiently identify and address vacuum leaks in your vehicle.
Understanding the common causes of a vacuum leak in your 2016 Mazda CX-5 is essential for effective DIY maintenance. One of the primary culprits is worn or damaged vacuum hoses, which can deteriorate over time due to exposure to heat and engine vibrations. Inspecting these hoses for cracks or breaks is a crucial first step. Another frequent issue is a faulty intake manifold gasket; if this gasket is compromised, it can lead to air leaks that disrupt engine performance. Additionally, a cracked or damaged intake manifold itself can be a significant source of vacuum leaks, so checking for visible damage is advisable. Don’t overlook the throttle body, as a loose or damaged component can also contribute to air leaks. Lastly, a malfunctioning brake booster can create vacuum issues, affecting both braking performance and engine efficiency. By identifying and addressing these common problems, you can enhance your vehicle's performance and prevent further complications.
Addressing a vacuum leak in your 2016 Mazda CX-5 is not just a matter of convenience; it is crucial for the health of your vehicle. A vacuum leak can lead to a range of serious issues, including rough idling, stalling, and poor fuel efficiency, which can significantly impact your driving experience. If left unattended, these symptoms can escalate into more severe problems, such as engine misfires or even extensive engine damage, resulting in costly repairs. The urgency to fix a vacuum leak cannot be overstated, as neglecting it may compromise your vehicle's performance and longevity. By promptly addressing this issue, you not only enhance the efficiency of your Mazda but also ensure a safer driving experience, making it essential for any DIY enthusiast to act quickly when they suspect a vacuum leak.
