Common OBD Codes by Vehicle Make

Toyota vehicles are known for reliability, but commonly trigger catalytic converter and evaporative emission codes as they age. Oxygen sensor failures and misfires are also frequent, especially on higher-mileage Camrys and Corollas.

Honda engines are durable but often see catalytic converter efficiency codes, lean fuel mixture issues, and VTEC solenoid problems. Misfires and oxygen sensor failures are common on Civics and Accords with over 100k miles.

Ford trucks and cars frequently trigger misfire codes, EVAP system leaks, and cam/crank sensor issues. The EcoBoost engines can show turbo-related codes, and the older 4.6L and 5.4L V8s are prone to ignition coil failures.

Chevrolet vehicles commonly experience EVAP system faults, mass airflow sensor issues, and catalytic converter codes. The LS and LT V8 engines may trigger oil pressure and variable valve timing codes as they accumulate miles.

Nissan vehicles are prone to catalytic converter codes, camshaft and crankshaft sensor issues, and EVAP leaks. The CVT transmission can generate transmission-related codes, and timing chain stretch is common on the QR25 and VQ engines.

BMW vehicles frequently experience VANOS (variable valve timing) faults, oxygen sensor failures, and EVAP leak codes. As mileage increases, misfire codes from aging ignition coils and intake air leaks are very common across the 3 Series and 5 Series.

Hyundai vehicles commonly trigger catalytic converter efficiency codes, misfire codes, and purge valve issues. The Theta II engines have known oil consumption problems that can lead to knock sensor and misfire codes over time.

Jeep models are known for EVAP system leak codes, especially on the Wrangler due to its exposed fuel system. Misfire codes, oxygen sensor faults, and variable valve timing issues are frequent on the 3.6L Pentastar V6 engine.

Dodge vehicles frequently show EVAP system codes, catalytic converter efficiency issues, and misfire codes. The Hemi V8 engines are prone to lifter tick and cam sensor faults, while the Pentastar V6 may trigger VVT and oil pressure codes.

Subaru boxer engines frequently trigger catalytic converter and oxygen sensor codes. The horizontally opposed engine design can lead to head gasket issues causing coolant temperature and misfire codes. EVAP leaks are also common across the lineup.
