Hello, im new to this forum and i have a question regarding my 03 Mazda 6 2.3L . I am having an issue with the TCS coming on while i rev the engine while in park, i can hold the engine at a certain rpm with out TCS coming on and making my engine stall so it falls all the way to zero rpm then back up to 2000 or 3000 depending on where i try to keep it at. Anybody have any idea what im dealing with ? Any input would be greatly appreciated.

 

What fault codes are you getting?

 

p0335 which is the crank sensor , ive had that changed but still does the same thing, what i did notice when it has a rough idle and its trying to stay on i put just a little down pressure with my hand on The CAM sensor thats mounted on the tip of the engine and the idle seems to even out , i dont know if these are two seperate issues or what
