With the scan tool connected It's showing the 5 volt reference voltage however, I've got a constant temperature scan value of 143 degrees with an outside temperature of roughly 45 degrees. I know it's going to show some variation of change but not that much, I've checked for the 5 volt reference Voltage at the sensor in the air inlet tube with a meter and have no voltage, I do have a good ground at the sensor pigtail so I can rule that out. If I knew which wire terminal at the ECM/PCM I could find out if the computer was actually sending the reference voltage, then I'd be able to confirm either a broken wire or a faulty computer. Can anyone help me out? I'm in hopes the years I've listed the manufacturer didn't make any changes !
