CSP sensor repair problem maybe F_O_R can help
Hello I have a 2008 pontiac Grand Prix that started
running really bad and stalling the other day. I got a
scan tool and checked the codes and i had a
crankshaft position sensor performance code and
a cam shaft position sensor code. This seemed
like the cause so I pulled the belt off, removed the
harmonic balancer and put a new crankshaft
sensor in and i figured since it was right there i
also put a new cam shaft sensor in. Put it back
together and i was proud that i manged to take
care of this. I cleared the codes and went for a test
drive. It immedietly started sputtering and stalled. I
hooked the scaner back up and i have a crankshaft
position sensor again and now an intake cam
sensor failure. Did i mess something up? 2008 with
151,000 miles. The car has beena. Good car we
bought it new. Any help would be appreciated.

I cannot know what you did but if the cam chain is loose it can throw off the cam timing. Which engine do you have?
Sorry @F_O_R I tried to link mybither thread where i posted the scaner pictures, and pics of everything I did so far. In the other thread Hornet suggested u may be able to help. Let me try to link the other thread again. All of the info is there. https://www.cargurus.com/Cars/Discussion- t31576_ds1005144
The engine is the 3800 series 3. I have photos of everything. I can repost if its easier.
Pre repair code

I removed the serpentine belt, removed the harmonic balancer and replaced the crakshaft position sensor and the cam shaft position sensor.

I also swaped the cam sensor while i was doing this. The I put it all back together and hooked up the scanner and cleared all codes. I went for a test ride and the car started sputtering and stalled very soon. I got it back to the garage hooked up the scanner and both the cam and crank messages were back.
Other code
All sensors were duralast from autozone. Ive since removed all sensors and took them back to AZ for new ones but i have reinstalled them yet. I plan to try that in the am. Is there anything i need to do that i may have missed when installing the crank sensor?
