Check eng problem???

[CRS]

My check engine light keeps coming on and giving me the PO 111 code which is the air temp sensor.I`ve replaced it and checked the wiring also which is ok but every time you get hard on the throttle it comes up with the same code again.This ski is really giving me nightmares,any ideas guys???

Further to my story i plugged in the stock ecu to see if it had the showed the same fault. As soon as you plug in the lanyard the little red light on the dash flashes continuously.I started her up on the trailer and within about twenty seconds the check engine warning came on and is showing the PO113 code which is also the manifold temp sensor.
