Hi there, I am Cam.what are the code numbers you are getting?
Ok so you have a problem not with that sensor but the 5 volt reference voltage that comes from the ECM. There are 3 different feeds and your issue is with #3. It sends 5 volts to the Map sensor(boost sensor), vane position sensor, EGR and the throttle pedal. What you need to do is clear codes, unplug each of these at a time and see if the other codes go away. If you have a scanner, you need to watch the #3 5V reference voltage and see what it shows. We have seen issues with the throttle pedal on this but it could be a short in the system or any of the sensors.
