2004 duramax oil pressure sensor

[Brando55]

Does anyone know where i would find the oil pressure sensor on a 2004 gmc 2500 duramax? Also, is it a hard job to replace it? Thanks

Welcome aboard!

It's threaded into the block, at the forward, left (driver) side, below the exhaust manifold. Once you get the wheel off and fender liner out, it's easy to access. A fairly straight forward job. Do it on a cool/cold engine, and it's easy.
