1997 nissan altima mass air flow sensor problems

I-75 hills, I can no longer accelerate to maintain speeds. About 300 miles later, it came back on and the car hesitates/bucks consistently with a loss of power once the speed hits about 60 mph. I cleaned the sensor, and the engine light went away. After these issues, I noticed the check engine light had come on for a mass air flow sensor.

After this, the driver side door no longer locks electronically, I have to lock and unlock driver side door manually but the passenger side does indeed work. After this, the radio unit would at times go completely black, causing me to have to turn the car off and back on. I replaced both speakers to find out that it is possible the in-car amplifier blew. Sometimes the car will recognize the phone, other times I have to disconnect the usb to phone connection, turn the usb cord around and reconnect a few times for the radio to recognize the phone. The issues with the electrical system started with the usb port connection to a cellular device. The cars electrical system started to have issues. If a fault occurs, a fault code is stored in the control unit and can be obtained using a diagnostics unit.This was a used pre-certified car, purchased from the dealer in which did not have any issues until its warranty was practically no longer valid. Conduct an electronic test of the MAF sensor by the engine management control unit.

Check the connection cables between the removed control unit connector and sensor connector for transmission (circuit diagram for pin assignment necessary). Check the output voltage with the engine running (circuit diagram for pin assignment is necessary). Check the voltage supply with the ignition switched on (circuit diagram for pin assignment is necessary). Check the measuring elements for damage. Check the connector for a correct fit and good contact. The following steps should be taken into account during MAF sensor troubleshooting: RPMs changing noticeably without driver input.

Excessive vibrations when stationary and/or Poor engine running at idle and/or surge Hesitation/stall on rapid acceleration “Check engine” or “service engine soon” light is on
