Default camshaft position sensor...

As I was driving back from school, I notice the "Engine Light" turning on. I was hoping it was a temporal problem but it stay on. Okay, so I took it to AutoZone. They check the error codes and it came up that the camshaft position sensor is not working and that I need to replace it. Of course, not knowing about cars...I didnt know what the heck it was and the dude told me that you need it otherwise your engine fail to start. I didn't buy it because I know I would be unable to install it. Well..I check online and I found out that its just a sensor for the timings in the injection fuel. Anyho, they all states its not a high critical component and unlikely for the engine not to start. Of course, I'll fix it until the next paycheck which is until the other friday..so meanwhile I will have to be driving like that. I was just wondering if its okay doing this with the car. I mean, I don’t notice any probs.temp is within range, pressure, battery voltage..everything, it works perfectly. Just wondering it wont do long term damage to my car. By the way, its a Mustang 95 V6. Thanks guys!

Real simple to replace. Same thing happen to my old 95 stang. I use to disconnect the battery and wait 30 minutes and the Check engine light would disappear for a week until it just kept coming up. By a hyanes manual and you will set to go. You car will drive no problem with the light on.

When you buy the sensor, you need to buy a special tool so that the cam sensor is installed correctly, or your whole ignition timing will be off. The tool goes for about $50.

I had to pull my timing cover off, which means removing the Camshaft Position Sensor. I marked it before removing it so I could put it back in the right place. I was having fuel problems and wanted to check the setting of the CMP to make sure it was correct. But, I don't have access to a tool (Ford T89P-1200-A), and I also don't trust a physical alingment. Searching on the web I found the following site.

http://www.asashop.org/autoinc/may2004/techtips.cfm

The tech tip is for a 1995-1998 3.8L Ford Windstar, I have a 1994 Ford Mustang 3.8L. Everything makes sense except for the crankshaft position. The tech tip says to turn the crankshaft to 26 degrees after TDC, the Chilton manual for my mustang says to turn the crankshaft to 10 degrees after TDC. Which is correct for the mustang?? The tech tip uses a volt meter for the adjustment, the Chilton manual uses a physical tool.

Also the physical alignment is tricky, when the gear engages between the CMP and the Cam, it turns the CMP a little as you seat it in place. Then I'm not sure if the alignment is correct. I must have it close because the engine starts and runs, but seems a little slow on acceleration and weak on power, but I have no check light. I would like to try the Tech Tip, but I am unsure which position to set the crankshaft at.

Anyone know how to set the CMP without the special tool??

Thanks for your post, your manual with my manual and other information really helps alot. The key part of your manual is:
"On a 1994 and 1995 model, position the number 1 cylinder at 26 degrees ATDC. On a 1996 model, position the number 1 cylinder at 10-degrees ATDC. On a 1997 and later model, position the number 1 piston at TDC."

I have a 1994 and with my manual set cylinder 1 at 10-degrees ATDC, THAT IS WRONG. Your manual clearly states the differences in the model years. Also I found a picture of the "Tool". at http://www.etoolcart.com/browseprodu...r-303-358.html
Cam Synchronizer 303-358 3.8 V6 camshaft synchronizer tool Necessary tool to synchronize crankshaft position sensor. Application: up to 1995 3.8L engine all. Same as Ford PN T89P-12200-A

With a picture of the tool, a small kids wooden ruler, and my speed square showing angles, I set my CMP correctly. Each notch on the CMP gear changes it about 10-degrees, so finding 54 degrees isn't hard. I laid the ruler along side the center half circle inside the CMP, (standing on the passenger side of the car, looking at the CMP with the half circle to the left) allowed the ruler to also drop into the slot on the CMP housing. Then using my speed square with angles lined it up at 54 degrees. It is kind of tricky holding onto several parts at the same time, but it is doable. As you seat the CMP body and the gears mesh, it turns clockwise about 10 degrees. After it is seated you can check the angle and lift it up and move it a gear notch to find the right angle.
