Quick facts
- Part: Walker Products 245-1237 mass air flow sensor
- Fits: 1999-2005 Suzuki Grand Vitara V6 2.5L and other vehicles
- Condition: New
A failing mass air flow sensor can feed the ECU wrong air readings, which may show up as rough idle, hesitation or a check engine light. Other faults can look the same, so before replacing the sensor, look over the intake duct and the sensor connector with the engine off and cool for cracks, loose clamps or oil film.
Fits
The 2001-2004 Chevrolet Tracker V6 2.5L and the 2004 Suzuki Vitara V6 2.5L fit this sensor too, along with more Suzuki and Chevrolet models. Open the "Vehicles it fits" section and look up your exact model and engine.
