Question about 2006 Kia Sedona
Code p2189 and p2187 = air/fuel mixture too lean on both cylinder banks which in turn generates excessive emissions = failed inspection.
What can cause a lean mixture:
- Incorrect main charge signal
- Intake air system leaking
- Fuel pressure too low
- Volume supply of fuel pump too low
- Mechanical fault in injectors
- PCV valve leaks
- Leaks in exhaust system
- EVAP canister purge valve mechanically faulty (hangs open)
All these must be checked.

Testimonial: "thank you for your answers well beyond my spec but now i'll know what the mechanic is talking about sounds like no easy fix"
Dwhen I got these codes in that same vehicl3 it turned out there was a crack in the rubber hose that goes from the air filter to the engine block. Once I replaced it ($50 part and the job only needed a phillips screwdriver and needle nosed pliers and 10 min). I pulled my battery which reset the light, then drove 100 mi to re-ready the computer and it sailed through inspection
