Question

2005 Mazda MPV with code P2189. How do I fix the code?

Answer 1

Hi there

This code means bank 2 is to lean at idle.

This is usually the result of a vacuum leak, mass air flow sensor or front O2 sensor. You can also get this code if you have an exhaust leak before the catalytic converter on that side of the engine.
