Worked well for my 2005 escalade. I believe it would work for 2004 Yukon. Hard to get to, but fixed my oil pressure gage result back to 45 psi. Was formerly pegged at 80 psi. Need 1-1/16 or 27 mm deep socket and swivel and extensions. 1/2 inch drive.

Oil pressure sensor for shevrolet Trans sport 2000. 3400 LA1 ?

You have to enter your vehicle year, make, and model to see if this part fits. Hope this helps.

Will this fit a 03 Chevy Tahoe flex fuel?

It fit my 03 Yukon with 5.3 so it should fit if you have same engine size. But mine lasted less than a week. I put a used brass one in from the boneyard and it has worked for over 6 months.
