Autozone pulled code p1135 on my Sienna 02, a Manufacturer Control: Fuel Air Metering Control, in their computers the part required is a <Mass Air Flow Sensor> . I read in other web sites that this is O2 sensor issue. I undrestand there is more than one sensor in the vehicle, any sugestion as to how can I make sure which sensor to replace?????
Thanks
