:confused::confused::confused:
I understand that the cam position sensor measures the revolutions of the gear on the end of the camshaft so it can tell the computer when to spray fuel. The part I don't understand is how the sensor works. I can understand that it measures the spinning of the shaft that it shares with the oil pump, but what I don't get is why it needs to be set at a 54* angle to the centerline of the engine. If the sensor is calibrated on the inside why does it need to point in a spacific direction? I've already marked on the outter casing where it needs to be put back, but the part I don't understand is how the cam sensor positioning tool is going to help me in getting the shaft turned to the right angle in relation to the sensor... Does anyone understand what I'm asking? Can you help me understand?

Thanks, you guys all rule

Well not only does fuel get input but so does spark so the relation the CPS is in will determine spark fire. So it also works in principle like a distributor. sending a signal to the coil pack when to fire a specific cylinder.

Right, but if that's all determined by the spinning of the shaft that is connected at the bottom, then shouldn't it only matter where the shaft is in relation to the CPS? Why the 54* requirement... Also, now that I'm thinking about it, why is it built so that you can spin it around in the hole, if it's always supposed to be pointed 54* from engine centerline.

because the car is tuned originalyl for how it is setup. If you move it from the 54* line its almost like moving its off a gear or two depending on how far its off.

Hhahahaha, I know this much, if it isn't right, it won't run, I got my 94 V6 off and I had to get that plastic tool and set it back right before she would crank and run at all.:rolleyes:

I don't think I'm explaining myself right. How does the tool work? Does it latch onto the sensor in some way to prevent the gear from moving when you put the sensor in again? I figure that the gear needs to be aligned with the sensor in some way. Does the tool do that as well? I was under the impression that the tool only alligned the sensor with the engine block.

Also, it says that you have to position it 54* from centerline. What do you use to judge centerline? How exact does it have to be?

Ok, now that I've acctually gotten the tool I understand how it works. I didn't realize that the tool not only helped you line up the sensor housing, but also made sure the sensor was in the right position inside the housing.

:mad: i might have to change my cmp sensor but how do i set the no. 1 piston at 10* atdc? and where do i get that aligning tool?

Piston one is supposed to be AT top dead Center, on a 99+. I've never heard of one being after TDC
