Cam sensor problems

I changed my cam sensor a few weeks ago and ulitmately thought I had fixxed te problem. After I expieranced upon just starting my jeep it choking and stalling out, I made a post and was going to get my crank sensor changed but boom the problem occurs again. Now my jeep is in the shop, CEL is reading 2 can sensor related codes... Any ideas? Thanks

Agree with tucsonzj on the codes helping for troubleshooting. And if you're having your codes read at Advance write them down when they run the test.

Rather than paying a shop big bucks you can test both the cam and crank sensors using the below procedures with an inexpensive multimeter.
