2007 Hyundai Tuscon CEL On With P0102 Code

So I have a 2007 Tuscon 2.0 Motor with 126k on it the car runs very well but last couple of weeks have been an issue. It started with a little stumbling at acceleration and at a stop the car would never stall and no codes at all. I did a tune up new plug wires new plugs and new air filter. The issue seemed to go away last weekend check engine light came on I got P0170 X2 And P0101 X2 so 4 codes in total. So took the MAF sensor off and used MAF cleaner sprayed as directed and let the unit dry. Reset the codes. Start the car no engine light. Drove it about 80 miles no issues shut it off. 10 Min later start it back up engine light comes back on P0102 low voltage to MAF. Checked connections all seemed good plugged it back in reset the code no issues again. Now what happens is when I reset the code and start it no fault codes come up. Its after I shut the car off and restart it thats when the code pops up. I tried switching out the MAF sensor and I tried leaving it unplugged to see if the car idles wrong or anything of that nature. Nothing happens whether sensor is plugged in or not. I dont have a meter to check for power to the sensor. I was reading that a faulty TPS sensor can cause this to happen is that true? When I unplug the TPS the car stumbles and stalls. Im just at my wits end trying to figure this one out.

Exactly how is a TPS going to generate a MAF code?
Have you checked over the intake snorkel and any associated hoses for any air leaks?

Thats why I was asking if the TPS post I read in a Hyundai Forum was true. I was seeing if anyone else had ever heard of that. It seemed very doubtful but with cars anything is possible. I have checked everything and no leaks are present.

After looking at both wiring diagrams, I don't see any relationship at all to those 2 circuits.
You're probably going to need a professional scan tool to monitor the data to see what is going on with that circuit.

I didnt think they were on the same circuit and i was surprised when i saw it on the hyundai forums. I managed to get my hands on a volt meter so I will be checking into seeing if i have power and ground going to the maf. I will post what I find probably tomorrow. Thanks for the diagram as well thats a huge help

Any idea where the map sensor is on the 07 2.0 ? Im having a hell of a time finding it. It looks like the map sensor is on that same circuit as well and i know that sensor is original with the car so its overdue to be changed out.

It doesn't have a MAP sensor.
