P200F: Catalyst System Over Temperature (Bank 2)
Standardized SAE J2012 code · P20xx — Fuel & air metering and auxiliary emission controls
What does P200F mean?
A temperature sensor in the exhaust catalyst on bank 2 reports a value above the safe operating limit. Sustained over-temperature can sinter the precious-metal washcoat and destroy conversion efficiency.
The code tells you which monitor failed, not which part is broken. Test before replacing parts.
Symptoms
- Check engine light on
- Failed emissions inspection
- Possibly slightly increased fuel consumption
- Sulfur (rotten egg) smell from exhaust under load
Common causes
- High Misfire dumps fuel into cat
