If the scanner shows a code related to the VVT system, as discussed earlier, the first thing your mechanic will likely do is check the VVT solenoids. These are like little valves that control the flow of oil to the VVT mechanism. Replacing them is often a relatively simple fix. If the code points to an oil consumption issue, start by checking for leaks. Look under your car and on your garage floor for any oil spots. Also, make sure to regularly check the oil level using the dipstick. If you're consistently low on oil, you might have an internal leak or be burning oil. This situation requires further investigation by a mechanic. They might do a compression test to check the condition of your piston rings or valve seals. Regarding catalytic converter issues, as mentioned, you might notice a loss of power or a rattling sound. Again, an OBD-II scanner can help diagnose the problem. A mechanic will likely check the exhaust backpressure to see if the converter is clogged. Depending on the severity, you might need to have it cleaned or replaced.

Before you start any repairs, always consult your owner's manual for specific instructions and safety precautions. Engine work can be dangerous, especially if you're not experienced. It's often best to let a qualified mechanic handle these complex repairs. Don't forget that regular maintenance is critical.
