While driving about five miles, my TCS light and check engine light come in and off. The check engine light finally just stayed on. I had the code ran and it P0340. I just had two crankshaft sensors replaced prior to this happening. Please help.

This code is for a problem with the cam sensor or the circuit, first thing to do is check and clean the cannon plug for the sensor and remove the sensor and clean and inspect for any damage, reinstall and clear the code, if the code resets I would replace the sensor.
