P1495 - Leak Detection Pump Solenoid Circuit

I was getting this code on a 1999 Dodge Caravan. We ended up replacing the leak detection pump solenoid from another van and placed it in the van with the problem and the problem still wouldnt go away. We then replaced the computer on the car with another one of a same type van, and that did not work. As soon as you turned the car on you would see the "service engine soon" light. In fact, you couldn't delete the code from the computer. As soon as you hit "erase" code on the obdII tool, the tool would indicate that "1 code still remains". So, to put the story short, we found out that the sensor had a cable that was "open" -- not making a connection to the computer. We concluded and tested this with a voltmeter and following the sensor to the PCM. 2 out of the 3 wires were okay. The one that was not making it through was the white with a black stripe.
