But these two P2187 P2189 Hyundai trouble codes can be caused by a faulty EVAP system purge valve. This valve is a common failure point. When the valve sticks open, the intake continues to suck fuel vapors from the charcoal canister. The oxygen sensor sees a rich mixture and commands a leaner mixture to compensate.
Hyundai?
