P1124 & 1126 (both banks):

Fault condition:
Fuel/air mixture so lean that sensing has reached its rich threshold.

Potential fault areas:
-- Failed MAF sensor
– Intake air system leaking
-- Air is introduced past the MAF causing the mixture to be more lean
– Fuel pressure too low
-- Not enough fuel to meet demand causing the mixture to be more lean
– Volume supply of fuel pump too low
-- Not enough fuel to meet demand causing the mixture to be more lean
– Fuel injectors fouled
-- Not enough fuel to meet demand causing the mixture to be more lean
– Exhaust system leaking
-- When the exhaust system has leaks before the front O2 sensor will cause the O2 sensor to report a lean condition (excess oxygen i the exhaust)
