MAF Sensor

[renos]

Codes P0102, P1128 and P1130 keep coming up. Is the Mass Air Flow sensor at fault?

Any other possible causes?

Thanks

P0102 Mass Air Flow Sensor – Below Limit

P1128 Oxygen Sensing Adaptation, Idle Range, Bank 1 – Above Limit

P1130 Oxygen Sensing Adaptation, Idle Range, Bank 2 – Above Limit

Potential causes:

P102

– Open circuit

– Short circuit to ground

– Mass air flow sensor

P1128 & P1130

– Incorrect signal from MAF sensor

– Intake air system leaking

– Fuel pressure too low

– Volume supply of fuel pump too low

– Fuel injectors fouled

– Exhaust system leaking
