Is it P0102?
Did you actually buy a new or refurbished sensor? You can expect your problem to be either the sensor, clogged air filter or the wires/connector, and that’s about it. The MAF sensor uses a wind resistor to indicate the amount of Air Flow into the intake or SC. The wind resistor, like every resistor, brakes down over time and their resistance properties changes, thus the voltage back to the cpu is no longer within its expected operating rage. Cleaning the resistor won’t do any good, it must be replaced. And be prepared, they can cost over 100 plus a core charge for your old one.
