Cam shaft position sensor

Hello i have a 2000 town and country. i used my hand code reader. got P0340 code replaced my cam shft position sensor 2 times. ive been told i need to have it set too top dead center befor installing sensor. which i remove # 1 plug i did a test where i had some turn the main crank untill i got it top dead center then put a screww driver in # 1 plug hole once i got the dive to move to the high point i bake off slightly to top dead center. put everything back on that i had to take off. cleard codes. then cranked it now start again. P0340 came back up again will not start. got this. replace tested it was good. still no start, not sure what to do next. i dont have many tools. and cant really afford to have it towed to the shop. any suggestions..

I moved your topic to the repair questions section where you'll get more help.
Before getting very much involved, can you provide the engine size of your Caravan?
I don't recall having to set the engine at TDC to change the cam sensor, but I'm not sure what engine you have, so I'd like to confirm.
Does your code reader have live data available?
Chrysler's generally have a PID for the cam and crank sensors as well as their synchronized status.
It is not uncommon for a Chrysler of that generation set a cam sensor code for a crank sensor issue or vice versa.
Do you have a multimeter you can use? Depending on where this goes, there are going to be some circuit checks that you will need to perform before condemning a part as faulty.

This in an oldie, but goodie that can walk you through the kind of circuit checks you're going to need to perform.

Its a 3.3 liter 2000 town and country. P0340 code.

hey there, the next step I would do is make sure you have power and ground at the sensor. I attached the wiring diagram and trouble tree for this code.

how many volts you have at the connector??

how many ohms of resistance do you have on the ground wire??
( i would put the ground lead of the DVOM on the neg battery terminal. )

and you can also check continuity from the signal wire to the ecm to make sure it is good.
