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. If you would like help having this P0340 code repaired, consider YourMechanic, as a certified mechanic can come to your home or office to inspect what’s going on in your vehicle for you and suggest or make the necessary repairs.
