For example, if you encounter a P0304 code (misfire in cylinder 4), you might check the spark plug, ignition coil, and fuel injector for that specific cylinder.
“Don’t just throw parts at the problem,” advises Sarah Johnson, a seasoned mechanic. “Systematic diagnosis saves you money and ensures you’re addressing the actual issue.”
Using OBD2 for Preventative Maintenance
Beyond diagnosing problems, you can leverage OBD2 for preventative maintenance. Monitoring parameters like fuel trims, oxygen sensor readings, and coolant temperature can help you identify potential issues before they trigger a check engine light. This allows you to address minor problems early on, potentially saving you from costly repairs down the line.
