Common Diagnostic Trouble Codes
P0300 – Random Misfire
Check spark plugs, ignition coils, fuel injectors, and compression. Often caused by worn spark plugs or vacuum leaks.
P0420 – Catalyst Efficiency
Catalytic converter below threshold. Check oxygen sensors first, then consider catalyst replacement.
P0171 – System Lean
Too much air or not enough fuel. Check for vacuum leaks, dirty MAF sensor, or fuel pump issues.
