ScannerDanner: MAF and wideband O2 sensor testing for a P0172 (Rich Condition)

The car being tested is a 2007 Suzuki SX4, but the methods shown apply to all cars. It is very difficult sometimes to identify the proper operation of a wideband O2 sensor and also the calibration of the MAF sensor. In this video, we cover both of these tests very thoroughly and are able to fix the car.
