How do you check a mass air flow sensor on a 1978 280z?

To check the mass air flow (MAF) sensor on a 1978 Datsun 280Z, first, ensure the ignition is off and disconnect the electrical connector from the MAF. Use a multimeter to measure the resistance across the sensor terminals, comparing the readings to the manufacturer's specifications. Additionally, check for any obstructions in the air intake and ensure there are no vacuum leaks. If the readings are outside the specified range, the MAF may need cleaning or replacement.
