Pulling a crankshaft sensor code, but car runs allright. Replaced sensor and nothing happened. What else could cause this code.

the crank shaft sensor feeds to your control module for your coils and you may have a bad ground or a chafed wire,,if you click on the post for the location of PCM in the Lumina by YCB in this forum there are two diagrams for the 3800 wireing from crank sensor and modules to PCM it will show you the wireing for your crank sensor and you can check your grounds with it. good luck!!
