Also, the engine almost sounds and feels like it is going to shut off when in idle. Is this a symptom of the engine recall? Doesnt seem to have any other issues other than that

 

Sorry I didn't see this post earlier

Follow the intake tube down in front of the car where it connects to the intake manifold. The first sensor is the TPS (Throttle Position Sensor) and the 2nd sensor is the IAT/MAP sensor (Intake Air Temp/ Manifold Absolute Pressure).

Hyundai Sonata: Manifold Absolute Pressure Sensor (MAPS). Repair procedures - Engine Control System - Engine Control/Fuel System - Hyundai Sonata YF 2011-2016 Service Manual

Measure the output voltage of the MAPS at idle and IG ON.
Test Condition
Output Voltage (V)
IG ON
3.9 ~ 4.1
Idle
0.8 ~ 1.6

 

locating the MAP sensor - Sonata 2011

C4RN1, After following your post, I am still having difficulty locating the MAP sensor on my Sonata 2011. I found a sensor, but it does not match the photo of the sensor on this site or in the Sonata repair manual. Please let me know if this is the part.

 

I am still having difficulty locating the MAP sensor on my Sonata 2011.

You fail to mention what engine is in your car but assuming it's the same 2.4GDi that OP has in his, you should find the MAP on the front of the engine beside the throttle valve...see below :

 

Thanks for your help, Autospark. After looking at your photo, I think I found where the MAP sensor is.
I was looking further up the engine, under the cam cover.
My vehicle is Sonata 2011 .4L L4 DOHC 16V

 

Hi there,

I own a hyundai Sonata 2.0T 2011. I am trying to figure out how many wires the MAP sensor connector should have. I've located both sensors, but I noticed the connector for the sensor close to the throttle body has only three wires with. The pin in position 3 has been removed and the wire appears to be missing. Is this normal?

 

The pin in position 3 has been removed and the wire appears to be missing. Is this normal?

Yes. These sensors have an air temperature sensing element built in but it's not used on both sensors.

 

Sensor adjacent to throttle body will have 4 wire, as it primary for main engine control pressure and air temp..

2nd sensor on tube before throttle body is used for boost pressure value only

 

ahhh okay. A bit odd, why not make it a 3 pin connector then?! So the sensors are interchangeable, its the connector that determines what information is taken?

 

Double check the part,, I think one of them only has 3 pin in it

 

Fair enough. Thanks for the information, you've been really helpful.

 

Both sensors have 4 pins in them, while the plug for the sensor close to throttle body has 1 pin and wire removed blocked under it. It just looks like an afterthought.
