What is the normal voltage readings for the MAF on a 2k-2k1 Maxima. Theres a RED wire, RED/SILVER wire, BLACK wire and a WHITE wire. My car has been acting up, and i think it may be the MAF starting to go out. I checked the voltage readings across all 4 wires, and the red/silver came up as battery voltage, red came up around 5.0x, black read zero as it should, and the white wire read 1.1v when key was in on position and engine was off, when engine was on it read 1.3v, and when revved up slowly to redline, it reached a maximum reading of almost 3.4v. I didnt have another 2k-2k1 maxima to compare readings to, only was able to compare to a 95 maxima, and it seemed like my readings from teh white(signal) wire were all a bit high.
