I was just looking at "Cranks but won't start" and I also need to replace my camshaft sensor, code 17746. I removed the cover and found the sensor on a long bracket, am able to feel inside the gear and, yes, the sensor is loose to the holder bracket. (surprised it runs) It does draw 5 volts as the book says to test the lead wires.
The book says the belt has to be rmoved and also the gear. Will I need a gear puller or will it just come off with a bit of wiggling and a tap with a rubber mallet?
Also, having done the timing belt a few months ago and not liking to do it again without the tensioner tool, please suggest a reasonable sourse to purchase one. I see one that sells for $39 and is machined, a bit pricy. (nice but very usable). Its raining out so this is next weekends project.

I have the red-handled tensioner tool from German Auto Parts:

GermanAutoParts.com

My only complaint is that bent part could be a little shorter to allow it more room to get into the tensioner.

The bolt that holds the pulley to the camshaft has a torque of 74 ft-lb, so you will need something to counterhold the pulley with while you loosen it. A strap wrench may work. The official tool graps the large cutout holes in the side of the pulley. It is keyed onto the camshaft with a Woodruff key so it shouldn't be too bad pulling it off. I doubt you will need a puller.

I just returned from internet shopping at Sears and missed your reply. I did however buy a simular tool. Your site has the three tool combo also, and I really do like the tensioner tool there but LOL really pricy.
Hoping to loosen the pulley before I take the belt off, and thanks for bringing that up. I will take a pic of my removed semi-broken sensor to post.

If you loosen the bolt by holding the pulley with the timing belt that will put a lot of strain on the belt. You'll need something to keep the crank from turning, maybe putting the car in gear if you have a manual transmission. I'd figure out something to hold the pulley with.

Myra helped with the sensor replacement yesterday. It turned into two people, I needed four hands and a wrench turner from the underside of the NB. I have the camshaft holding tool coming, its ordered. ( Still need to torque the bolt properly) We have it running and a pleasant surprise, the shifting problem with the techtronic of not wanting to go up a gear by itself..........gone. Myra was having to let up on the gas to shift, like a stick.

Some pic of interest....
old sensor, broken but still ran
new sensor
transmission looking hole for TDC
I also found an opening on the underside of the transmission for the flywheel, good for seeing the elusive O as a practice place.
