Warning Light.jpg

Hello everyone. I'm needing some help troubleshooting my 2008 328i. My brake light, car on a light warning light, and a triangle with a circle light is on, and its throwing code P1727. The car hesitates to start, and has a rough idle. When driving on the highway it feels like it doenst have power. Any insight would be helpful.

It's a crank sensor fault

Thanks for the response Saii. I've replaced both of the camshaft sensors and problem is still there. I want to make sure its the eccentric crank sensor before taking my valve cover off. When looking at the eccentric sensor, its not saturated with oil like others have stated.....so i guess im not 100% if it has just gone bad.

Um the crank sensor is located under the starter and when replacing it you have to replace the bolt since its the blue one time use

The eccentric cam sensor controls your idle, cam position and something else I can't remember but it's not related to the code p1727
