Default Clean camshaft sensors - 2.4 L

If anyone has experienced a loud knock or scrape sound @ startup may try cleaning their intake and exhaust cam sensor assemblies.

They are located on the far left hand side on top of the engine. Remove the engine cover and you will see them.

They are held on by 10mm bolts. I removed them and soaked them in parts cleaner up to the rubber o-ring. The screens were a little dirty, but nothing too bad.

I then sprayed them off with electronics part cleaner to remove any residue and let them dry.

Lastly I filled a small cup with 5/30 oil and dipped them to the o-rings making sure oil filled each one.

I then reinstalled them being sure not to over tighten. Both the sensors and head are labeled INT for intake and EXT for exhaust.

I did notice the subsequent starts were more quiet, need to wait and see if there is any grinding or slamming on startup anymore.
