2011 chevy silverado code po335 still starts and runs when

Customer Question

2011 Chevy silverado code po335 on code scanner. Still starts and runs. When starting starter continues to crank for a few seconds after engine starts. The tachometer doesn't work and it shifts very hard when driving. Engine stumbles slightly occasionally. There is only 46,000 kms on truck. CheckTracking control triangle shows up on instrument panel, and stablizing off. Drove to work in morning 20 kms highway worked fine. Left to go home from work, acted up soon as I tried to start it. Starter ran on longer after it started running. Where is the crank sensor located on the 4.8?
