It has two of them. They are under the intake manifold. You have to remove the intake to change them.

How to replace the knock sensor on a 2004 cheverolet 2500 6.0 liter engine


Hello Friend:

Your Anti-Knock Sensor is Located With Hood Raised Facing the Engine Compartment,Its on the LEFT SIDE Right Under your Exhaust Manifold Towards the Back.

On the Engine Block ,You'll see Your Anti-Knock Sensor Wires running to it.

Its a Little hard to Get to but Not so hard that you can't do it Yourself.

Disconnect the Wire Connector, And Take a Good Look at the Wires,Since it Runs so Close to your Exhaust you could have Also some Faulty Wiring going to the Sensor.

Just Un Screw the Anti-Knock Senser and Replace New.

This will get your Anti-Knock Sensor Replaced With A New One Like i Said Look very Good at the Wiring Going to the Sensor.

Thanks for using FIXYA Please let me know how i've helped you by Voting and If you Would write a Small Testamony.

Thank You: From d_hubbs

You have to remove the intake and they are under rubber caps in the lifter valley.. 1 is the front and 2 is the rear. This is not a hard job but requires special tools for the fuel line fittings or quick disconnects. They intake gaskets are fairly expensive but if you have average skills you can do this in an afternnon easy.
