I'm running the AEM EMS standalone computer, and awhile ago the GM air intake sensor that came with it stopped working. Or at least that's what it seems. The AEM is reading 5 volts from the sensor all the time. I just measured voltage at both wires going to the sensor... one reads 5 volts and the other read .08 volts. Neither voltage changes when I heat the sensor with a heat gun so I'm assuming it is defective. I was expecting to see 5 volts on one wire and around 1-3 volts or so on the other. The outside temp is 70 F. Should I go ahead and replace the sensor? If so, why would it randomly die? Is this common? Thanks.
