Nissan xterra mass air flow sensor symptoms

If the MAF sensor hot-wires were not dirty (contaminated), then re-install the MAF sensor back onto its housing and go to TEST 2. Do not disconnect MAF sensor connector from the MAF sensor. We can't just use any type of solvent to clean the MAF sensor with. With the BLACK lead of the multimeter probe BATT (-) negative terminal. Without this voltage the MAF sensor will not work. Be careful and take extreme care not to short-circuit this wire to ground or power as you're probing it. If the MAF sensor hot-wires were dirty (contaminated), clean per the suggestion given above. Also, don't attempt to physically clean the sensor with anything (like a cotton swab) or you may break the wires. Then further testing is required, go to TEST 2.
