Thread: 02 Suburban cam sensor.

Tweet

Well I did the cam sensor today.
It's very tight, but still not as hard as I thought it would be.
I had to remove the cover or gaurd on top of the intake and the three bolt
plate that holds the back of the cover down. The Cam Sensor is to the passanger side of the oil sending unit, right behind the intake manifold. The best way I found to get to it is to take a 10mm socket with a swivel and a couple long extension with a ratchet.
Feed that to the back of the manifold from the drivers side while reaching around the passenger side with your other hand and guide and hold the socket on the bolt.
After you get the bolt out, twist the sensor from side to side while pulling up.
It should pop out, now you can remove the clip with the wires on it.
Now take the new cam sensor and put some clean oil on the o ring, then slide it in to the hole you removed the old one from. You may have to use your socket and extensions to push down on the top of the sensor to get it all the way down into the hole.
It's in a tight spot, so that was the only way I could get the sensor to seat all the way.
Now put the bolt back in and plug the wires back to the sensor, replace the plate that holds the back of the cover down, the put the cover back over the intake manifold.
All done, thats all there is, oh remove negative side on the battery to reset the codes.
