Just letting you know code 47 is open or short in circuit for sub throttle position sensor. This is for the Trac system and if you are looking at the 2 throttle it's the one on the left. It's called TPS for short. I replaced mine and the engine light went away. Be sure to disconnect negative lead on battery for 1 minute. Also make sure it is installed correctly the blades have to be able push against the lever inside the sensor. If you continue to receive light you may have an open circuit in the wire or ecu not sending signal you can check by putting ignition to on without starting then (check for 5 volt reference with ohmeter set to 20 vdc). With one lead on term inside harness and other to ground. Hope this is helpful.
