Default Cam Position Sensor Pulling Double Duty?

Hello All,
I have read (in fact, on this board!) that the cam position sensor also doubles as the cam tensioner for our cars (I have a 06' GT Cruiser 5spd.). I have the replacement Mopar sensor ready to be installed. I told the mechanic who is going to install the sensor about the bolt tension needing to be 115 inch pounds. He said "though he has done SEVERAL of this common P/T Cruiser problem cam sensor. He has never heard of it doubling as the tensioner." Can you guru and weekend mechanics confirm this to be the case one last time for me. Maybe, arm me with some solid information so that I can kindly make my point to make sure he does tighten the bolts correctly. Thank you in advance to all.

Bryan

i can verify that your info is incorrect. the sensor is a sensor and the tensioner is a tensioner

the sensor is on the drivers side of the cylinder head, right above the transmission. the timing belt tensioner is on the passenger side of the engine block next to the waterpump

you also instructed him to over tighten it.

from ALLDATA Pro:
>>
Install camshaft position sensor. Tighten sensor mounting screws to 9 Nm (80 15 in. lbs.) torque.

Ditto! Just a sensor.

Per 2001 factory Chrysler Sebring manual: For 2.4 engine, the torque spec IS 115 in-lbs. [same engine]. Something more interesting is that the torque spec for the magnet behind the sensor is only 30 in-lbs! Overtightening might crack the magnet.

Make sure that the magnet is clean.

I could use a cold one right now. Yaah.

Glad that was settled. Soon as I saw the first post I grabbed both the Haynes and Chilton manuals to look up the torque settings. They list it as the CMP 115 in-lbs and magnet retaining screw as 32 in-lbs.

Got to admit that I can't see anywhere in those particular manuals that says anything about the sensor being a tensioner but I usually don't put anything down that I haven't read somewhere but was already mentioned ....you can't believe everything you read on the internet.

Thanks to everyone involved.. glad I didn't argue with the guy! He may now install it freely and I know he knows what he is talking about. Thanks again.
