Yes you do, because I just did that an hour ago.. Good luck!!
sensor assy vacuum
If you mean fuel level sender-in the tank, most likely part of pump assy
the sensor is part of the fuel pump assy and comes out through a hole underneath the matting in the trunk.... remove the cover and remove lines from assy and then remove assy from tank.....make sure to relieve pressure from fuel lines before you remove lines due to residual pressure in the lines...
On/by the Throttle body, should read "sensor assy map"
on the air filter housing assy
I believe it is part of the wheel bearing/ hub assy.
There is a fuel temp sensor mounted on a bracket inside the tank and a low fuel sensor on the fuel pickup assy...
The 2011 sonata does not have a maf it has a map sensor or manifold absolute pressure sensor located on intake manifold near throttle body assy.
it's attached to the r/s tail light assy.
fuel filter is a strainer ( screen) in the tank- I just removed the filter pump regulator assy. from my 2000 wrangler with 112000 mi - what a disapointment. the engineers obviously had no practical education. the oring and plastic tube that connect the regulator to the pump are worn out. this lets the pressure in the fuel line leak out and causes hard starting- only fix is a new pump assy, 235.00 rockauto.com
If you have a carburator, there is no position sensor. If you have a Throttle Body or fuel infection, it is on the same shaft that moves the butterflys inside the assy. Where your footpeddle cable and cruse control cable connects, the position sensor is on the opposite side of the throttle body from that on the same shaft. Held on the side of the assy by two small bolts with a electrical connector.
the manual release lever is attached to the parking brake pedal assy
