Hi, I'm Don from 1A Auto. I hope this how-to video helps you out, and next time you need a part for your vehicle, think of 1AAuto.com. Thanks.
In this video, we're going to show you how to replace the camshaft position sensor on this 2002 Chevy Suburban, and it's the same part and similar process on the Suburbans from 2001 to 2006. The items you'll need include a new camshaft position sensor from 1AAuto.com, a flat blade screwdriver, an 8mm and 10mm socket and ratchet with extension, a fuel line disconnect tool (in this case a 3/8 inch), pliers, a vacuum, penetrating fluid, and a torque wrench.
Start off by removing the 8mm bolt that holds on your engine cover. That pulls free. Then, using a flat blade screwdriver, just loosen up this hose clamp right here and this hose clamp right over here. Now, you can pull the hose free. Pull it free from this side, then just lift it up and pry out the hose from the intake hose. Then it's free. Now, remove these three 8mm bolts right here. We'll fast forward as Don does this. Then remove these three 8mm bolts right here.
Next, disconnect these two harnesses. To do that, you just pull up on the tab and pull them free. Then pry this hose right here free, and then remove these three 10mm nuts. Lift up this bracket and pull it aside, and then remove this 8mm bolt right here, and then just pull that bracket aside, and then disconnect this hose clamp, and do the same thing back here with this one. You want to make sure you disconnect that harness as well and pull that aside. Do the same thing back here, until this set of harnesses loosens up. Then just remove this 10mm nut right here, and then you can just pull that set of harnesses aside. Then pull up the clip on the harness for your fuel injector, then push the tab on the harness and disconnect it, and repeat the process for the other seven.
Now, just loosen up this fuel line cap, and using a flat blade screwdriver and a rag, you want to just put the rag over it and push the tab on the fuel bleeder. It should spray out just a little bit, and it'll release the pressure. Then replace the cap and come over here and just pry off this clip. Then, using a fuel line separator tool, you just want to push that all the way in. For this one, it's a 3/8 inch. Then, once that's pushed all the way in, you can pull the fuel line free, and then it just pulls off. You put it on the fuel line below it and repeat the same process. Take a pair of pliers and push the teeth together on this hose clamp. Slide it down the hose, and then pull the hose free. Then just remove this series of 10mm bolts along each side of your intake manifold. You can kind of see them, they're down below the fuel rail there. We'll just fast forward as Don removes these.
Lift your intake manifold up and out. You will have to maneuver a lot of harnesses and wires and everything but you just want to get this out as far as you can get it to go, which at this point should be right about here. Once you get to this point, take your EGR and just feed it through the harnesses and out. Once you feed it through, you can just lift your intake manifold up and out.
At the back of your engine block you'll see this harness. Just lift up the tab and disconnect it and remove that 10 mm bolt. We'll fast forward as Don does that. Now, using a flat blade screwdriver, just pry the sensor up and out. On the left is the old camshaft position sensor; on the right is the new one from 1A Auto. You can see they're identical and they'll fit exactly the same. Push the new camshaft position sensor down into place. Then just replace that 10 mm bolt. We'll just fast forward as Don tightens that up.
Reconnect your harness. Set your intake manifold back down into place, then just feed this hose down and pull it out through the other side. Now, disconnect your EGR by just pulling out on the clip with a flat blade screwdriver and just pulling the hose free. Then feed that hose through the side of your intake manifold. Just maneuver it down and into place. We're going to fast forward as Don continues to do this. You just have to move the cables and wires around until you can finally get it to set down, it does take a second but it will go down. Now reconnect this hose. Just using pliers, slide that hose clamp back into place, and then reconnect this bracket. You want to just line this up and push it back onto those studs. Then just replace those nuts.
Take the EGR valve and push it back down into place, and replace the bolt that holds it there, and then reconnect that hose. Reconnect your other hose to the top of your intake manifold, replace this bracket and replace the bolts that hold it into place, reconnect this hose over here, and then replace this bracket and the bolts that hold it into place and just tighten those up. Then just replace each of these long 10mm bolts that line the side of your intake manifold, and then just tighten each of those up. You can see that we use a variety of different extensions just to help get there. You can use a longer one for these ones, then, as you get further back, you may need to use a shorter one. It does help to have a flashlight, too. Just make sure you reconnect your fuel lines, and then put those clips back into place to lock them.
Okay, you want to torque the manifold bolts. Start in the middle and go across, then work your way around the manifold in a counter-clockwise pattern. You want to tighten them on the first pass to 44 inch pounds, then 89 inch pounds. Now, just reconnect each of your fuel injectors. You just want to push the harness in and replace that clip and push it down into place. We'll fast forward as Don does this to the other fuel injectors. Lower the intake hose back down into place. You just push it back and then tighten up those two hose clamps. Double check that all your harnesses are connected and all the hoses are connected, and then replace your engine cover. Once you get it lined up, just replace that bolt and tighten it up. Then you're all set.
