23/04/2020· How to Test the Mass Air Flow Sensor in a Nissan Truck. Locate the MAF sensor. Depending on the year and model Nissan truck, the sensor could be located in the air duct or anywhere on the engine block. Set a voltmeter to volts. Stick a pin or needle into the MAF signal wire. Have your assistant push hard on the gas pedal then release it.
The complete air mass sensor consists of a flow passage (tube), in which the intake air flows past the sensor unit itself. NOTE: Depending on application and vehicle, the air mass sensor is available as a single plug-in module, or fully integrated min a plastic tube. Both versions – with or without tube – are referred to as air mass sensors. Older models have a hot-wire sensor element. Any ...
