Have you by any chance taken a multimeter & tested your TP (throttle position) sensor ? If you think you might know how, let me know & we'll guide you through it. If not, at least take wiring plug off & clean both plug & TP sensor contacts with contact cleaner, and inspect for any corrosion while doing it. When putting plug back on, use a little di-electric grease in the connection. Have you sprayed your throttle body & throttle plate good with throttle body cleaner recently?

I discovered that its the throttle body sensor. Its not sensing the postion of the foot pedal. The throttle body has a sensor that is linked to your gas pedal via a cable. The spring that the repair man mentioned could be the issue. The sensor then communicates to the computer the position and then computer then applies fuel, the mass air sensor then will communicate to the computer and the computer will then allow more or less air to fuel ratio. So if your stomping on the gas and there is not any response, then your throttle body sensor is most likely going out.

P0340 is for camshaft position sensor circuit malfunction so the problem can be in you hav already changed sensor, then you need to check wiring from sensor to ecu and if the wires are ok than check the ecu! It can be either of them cousing the problem.
