I have a 2008 Sportsman 500 EFI and have a trouble code of 47. IAC open or shorted to ground. I checked the ohms on the pins of the IAC as per the service manual and all checked ok. I checked the voltage on wires 2 and 5 on the connector and had battery voltage. I checked for continuity on the remaining wires from the connector to the ECU pins and was good. I checked to see if there was continuity between the ECU harness and ground and got nothing. I then replaced the the IAC motor and still get the code 47 and the atv will not idle. What is the next thing I need to try to fix this issue?
