    Has any one come across trouble codes P2187 and P2189? Leo's definition is "self-learning of additional air value for air-fuel mixture ratio" and "additional air value self-learning cycle for air-fuel mixture ratio LH bank". The generic descriptions are "lean at idle bank one and two". Thanks in advance.

    Victor- Your caps button is stuck. Four years ago and nobody knew back then. Here it is for the 575M, also an F133 engine. P2187 is bank 1.

    Long Term Fuel Trim Additive Air (Bank 2) ( P2189 ) ● Incorrect fuel self-learning, air percentage injected too high ERROR TYPE Rich fuel value VERIFICATIONS Check all the devices relating to carburation/combustion (sensors, air-flow meter, spark plug injectors, coils), all the mechanical parts relating to emissions (engine timing, valve seal, exhaust manifolds etc.)
