Hello guys/gals!
2005 Hyundai Tiburon V6 2.7L
On Saturday the 6th I was told by my mechanic I needed a new Mass Air Flow Sensor. I replaced the Sensor ([URL=”http://www.autozone.com/engine-management/mass-air-flow-sensor/duralast-new-mass-air-flow-sensor/hyundai/tiburon/2005/6-cylinders-f-2-7l-mfi-dohc/337335_0_12219/?checkfit=true”%5DThis One[/URL]), turned on the car, and then it idled terribly. I drove it just thinking it was okay since it was new. Every time I went to start the car it would Idle terribly so I thought I might have a bad sensor, even with no CEL’s. Today I replaced it with [URL=”http://www.autozone.com/engine-management/mass-air-flow-sensor/cardone-reman-mass-air-flow-sensor/hyundai/tiburon/2005/6-cylinders-f-2-7l-mfi-dohc/779924_0_0/?checkfit=true”%5Dthis one[/URL] from AutoZone as well.
Now the car will start up perfectly fine and the idle is good but I am getting the P0102 code.
Is this a wiring issue? Sensor Issue? What do you guys think? If I had a lab scope I could do some test but I do not.
Thanks!

You don’t necessarily need a scope yet. In spite of not knowing which one would be the “A” circuit, you can still test power and ground with a good voltmeter. At the MAF sensor, my wiring diagram says that the orange wire will be battery voltage and the black wire will be ground.
Check your 5 volt reference and ground and you can also check your signal wire to see if you are getting some kind of signal with just a meter. Have seen plenty of “NEW” parts especially aftermarket be bad right out of the box especially remand units.
I don’t know what happend with the MAF but as soon as we put the old one in everything worked good and the code went away….Now for the bad part
Driving down the highway and the car started to misfire.
I have replaced plugs and wires, coils, and Crankshaft position sensor
I have had it to the mechanic 3 times. Each time the car was returned saying it was Okay
Codes: p0301, p0302,p0305,p0306,p0300
Any advice?
Just for the heck of it check for air leaks in the tube that goes from the MAF sensor to the engine. Any air leaks hear will cause performance issues. More info on solving these issues here.

Please keep us updated on your progress.
There are lots of videos on how to clean MAF sensors.
I did my BOSCH Hot Film MAF sensor cleaning, and, of course, I damaged it. Although it was looking in a good shape after disassembly.
It failed, and I bought a new one.
So, I don’t recommend cleaning, if you are thinking to do so.
