ACDelco 15114379 Tire Pressure Monitoring System (TPMS) Sensor

• -

this is a GM origanal part that comes with 2005 suburban LT and similiar GM vehicles. I had this installed at a local shop for 30 bucks. The dealer charged me 200 to replace a different one, I wont ever do that again, complete rip off. I went to a tire kingdom and they wouldnt install unless i bought part frm them for 70 dollars and 30 to install. once you install you have to "program" the vehicle to read new sensor. You also have to do this whenever you rotate tires. This procedure is in your manual that came with car. You will press emrgency brake down, turn ignition to On position without actually starting car and switch headlight swith four times to on and off quickly, horn will beep meaning it is in tpm programming mode. You will have i believe 60 seconds to go in order Front left, front right, rear right than rear left tires and let air out of each in that order until you hear horn beep. that tellls you the vehicle is recognizing each sensor. When done just fill tires back up to reccomended pressure. Mine is 32lbs psi. Also every car has a tag inside driver door that shows reccommended tire pressures.

Ordered for my brother's Suburban, fast delivery, fits and works perfectly. The batteries go dead on these, and if one goes, you can imagine others will. Not a bad idea to get a spare.
