Q: Changed camshaft sensor but car still won't start, could it be the crankshaft sensor?

Hello, thanks for writing in. Most of the time, this code comes up when there is a difference between the crank and cam sensors. The most common failure is the crankshaft position sensor. These fail much more frequently than the cam sensor and will cause a no start. It can also occur if the timing belt broke or jumped a tooth. I would do a compression test also to see if there is low compression. If there is then the timing belt is the problem.
