CEL code 1126, 1133 and 0154

P1126 Oxygen Sensing Adaptation, Lower Load Range, Bank 1 - Below Limit
P1133 Oxygen Sensing Adaptation, Lower Load Range, Bank 2 - Below Limit

No idea what P1054 is.

Probably a MAF problem, but could also be:

– Intake air system leaking
– Fuel pressure too low
– Volume supply of fuel pump too low
– Fuel injectors fouled
– Exhaust system leaking

Thanks. Think I typed wrong. Think may be P0154. I'm at work and it's at home so I can't check it.

What would my best course of diagnostic action be from here?
