Working on a 2000 7.3. It has what I thought was really bad turbo surge just rolling down the freeway with the cruise set at 70. It tunes out that the waistgate solenoid is opening and closing over and over and over. With the key on but engine off you can hear it opening and closing and it won't stop. Checked the MAP sensor and its showing 14.3 while the EBP sensor is showing 14.7. Was going to replace the MAP sensor anyways cause the plastic tab that keeps the plug locked onto it. None the less when I unplug the MAP sensor the waist gate solenoid keeps cycling. Do you think the waist gate solenoid is being told to do that and the issue is else where or its acting up its self? Was going to see what the voltage being fed to it is does any one know what I should be seeing with the key on engine off as far as volts go?
