On an ISX, they are called the Cam Position Sensor and the Crank Position sensor. Register your engine with Quickdserv.com and you can look them up in the diagrams. The crank position sensor is located just behind the crank shaft damper on the driver side of the engine block, and the other is mid-way of the head on the drivers side, just below the engine brake harness.
If you are getting sync errors, then you need to also do the following when replacing.troubleshooting these types of errors...
* Check the tone wheel for the crank position sensor to ensure it has no free-play to the crankshaft. It should absolutely be tight and unmovable to the crankshaft. this can be checked by using a small flat screwdriver on it through the hole for the sensor and looking in with a mirror.
* Check to ensure there is not a spun bearing in the head on the injector cam near where the engine brake harness goes into it. Excess vibration of the injector cam from either a spun bearing or the bearings worn badly and showing copper can cause sync errors due to excess internal vibration of the cam.
* Use the #4 wedge in the static timing kit to ensure the injector cam has not slipped by comparing the insertion position to the position marked "INSERT PIN" on the crank shaft damper. If the Injector cam has slipped (it does happen on them, especially if someone has had it out and did not follow exact procedure on re-instillation), this will throw off the cam position sensor, and will cause sync errors if it becomes severe enough. It also causes excess soot problems with the engine.
* Check the free-play of the clutch pedal of the truck. If there is zero free-play, then the constant minor spring force tension onto the flywheel will wear out the crankshaft thrust bearing and make the crank ride forward in its cradle. this in turn can cause a misalignment of the crank sensor to the tone wheel, and is also a very bad thing to have, due to excess thrust-play on the crank.

Damn Rawze, you nailed the shi#t out of that one!!
I get a kick out of every post you make that solves some crisis that truckers have been suffering through and need help with; because the jackasses at the dealerships don't know how to do diagnostics.
Every time you post it's a scorcher like whiskey but man it's good stuff.
