2008 Mazda CX-7 Grand Touring 2.3L sensor code P0101

VEHICLE:  2008 Mazda CX-7 Grand Touring 2.3L, L4, MFI, DOHC, Eng Desg MZR

MILEAGE:  66,259

Customer Concern:

The engine is a bit low on power at higher speeds and Mass Air Flow (MAF) sensor code P0101 is present.

2. Check boost pressure in the intake manifold to determine if the turbocharger is boosting or not. If not, the turbocharger may be faulty.

Potential Causes:

Restricted Exhaust System

Confirmed Fix:

Replaced Turbocharger
