Hi,

Looks like Pin 1 (black) is sensor ground. Pin 2 (light green/black) is MAF ground in the PCM, Pin 3 (white/blue) is battery voltage. Pin 4 (green/red) is the signal wire to the PCM.

I attached a couple shots of the wiring diagram if that helps. Please let me know if you need more information. Thanks

Unfortunately my Hyundai has got a MAP sensor on the manifold with no MAF sensor on the air intake. I cannot find any information on four wire MAP sensor. The workshop manual I bought a while back has only MAF sensor on air intake. The engine is a GF4K 1.5 dohc version. Any reply appreciated thanks!

I am sorry. This was a 1.5L SOHC. We unfortunately do not have a manual/book for the DOHC.

I can see the trouble you are having. Let me do more digging and I will see what I can find.
