maf sensor signal pin to the computer resistance, what reading? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I am trying to test if my maf is bad or my computer.

Could someone please remove their 91-94 s13 maf harness and tell me what resistance they are getting from the harness connector maf signal wire to ground, with the harness disconnected?

I am getting a little over 20k on my ohm meter.

The maf isn't sending any signal volts when I check with a push pin and volt meter while running. Wire is good, tested perfect continuity, no resistance from ecu connector to maf connector.

Now I just got to eliminate whether the computer or the maf is screwed. Thanks!

? Anyone, really?

What makes you think the computer is bad? Did something get shorted out

Nah, just covering all my bases. Been chasing a big flooding issue

Never mind. New maf has proper signal. I just like to test everything instead of throwing parts at problems.

Hey your flooding issue, did you fix the problem with a new maf? My S13 is flooding with fuel, injectors are not leaking, somthing is telling my ecu to spray fuel and keep spraying
