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 a 2019 Toyota Yaris, start with a thorough visual inspection of the engine bay. Look for any damaged or disconnected vacuum hoses, paying close attention to cracks, holes, or loose connections that could compromise the system. Next, listen for any hissing or whistling sounds while the engine is running, as these noises can indicate the presence of a leak. If the source remains elusive, consider using a smoke machine, which introduces smoke into the vacuum system, allowing you to visually identify where it escapes. Alternatively, spraying soapy water on the hoses and connections can reveal leaks through the formation of bubbles. Additionally, monitor the engine's performance for symptoms such as rough idling or stalling, which may suggest a vacuum leak. Finally, utilize an OBD-II scanner to check for any diagnostic trouble codes that could provide further insights into the issue. By following this structured approach, you can systematically identify and address vacuum leaks, ensuring your Yaris operates smoothly.
When diagnosing a vacuum leak in your 2019 Toyota Yaris, it's crucial to recognize the common problems that can arise. One of the primary culprits is damaged or deteriorated vacuum hoses, which can crack or become loose over time, leading to air leaks that disrupt engine performance. Additionally, a faulty intake manifold gasket can also be a significant source of vacuum leaks, as wear and tear can compromise its integrity. Cracked or damaged vacuum fittings are another frequent issue, as they can easily develop leaks that affect the entire vacuum system. Furthermore, a malfunctioning throttle body, particularly if the throttle plate is stuck or damaged, can exacerbate vacuum leak symptoms.
As for the symptoms, a rough idling experience is often the first noticeable sign, indicating that the engine is struggling to maintain a steady RPM. You may also notice a decrease in engine performance, with a lack of power during acceleration. The check engine light may illuminate on your dashboard, serving as a warning that something is amiss. Additionally, listen for any hissing or whistling noises emanating from the engine bay, which can be a telltale sign of a vacuum leak. Lastly, if you find yourself facing hard starting issues or frequent stalling, these could also be linked to a vacuum leak. Addressing these problems promptly is essential to maintain the health of your vehicle and ensure it runs smoothly.
Addressing a vacuum leak in your 2019 Toyota Yaris is not just a matter of routine maintenance; it is crucial for ensuring the vehicle's optimal performance and longevity. A vacuum leak can lead to significant issues such as poor fuel efficiency, rough idling, and even difficulty starting the engine. If left unattended, these problems can escalate, resulting in increased fuel costs and potential damage to critical components like the catalytic converter. The engine may run lean due to the excess air entering the system, which can cause overheating and further complications. Additionally, neglecting a vacuum leak can severely impact the drivability of your Yaris, leading to stalling and engine misfires that compromise safety on the road. Therefore, it is essential to address any signs of a vacuum leak promptly to avoid these risks and maintain the reliability of your vehicle.
