REACH 4-Piece Upstream & Downstream Oxygen Sensor Set For 2006 GMC Sierra 1500 Classic & Yukon 5.3L
About this item
Is your 2006 GMC Sierra 1500 Classic, Yukon XL, or Yukon with the 5.3L engine throwing a check engine light?
Bad oxygen sensors are a common cause.
This REACH 4-piece set includes both the upstream and downstream O2 sensors—all four of them!
That's sensors 1 and 2 for both the left and right sides.
They are direct replacement oxygen sensors (not air/fuel ratio sensors).
They cross-reference with a bunch of numbers including 234-4336, 234-4337, SG1066, 15282, and ES20008.
They come with a 1-year warranty.
If your sensors are old and slow, replacing them all at once can restore fuel economy, improve engine performance, and get rid of that annoying check engine light.
They're brand new and ready to bolt in.
Give your GM truck or SUV some fresh sensors and get it running right again.
This REACH set is a smart, complete solution.
