What could be my problem? I have tested for power at 30 and 85 and 86 and they have power when the keys on. The pressure seņor has 5 volts and jumped it and it still doesn't kick on the sensor on expansion valve is good. I jumped it and it still doesnt turn until I probe the terminal with my test light. Does the ambient temp sensor have anything to do with the ac system?

Had errors in last post.

The pressure transducer is not an ON/OFF switch. The resistance value is calculated by the PCM as a pressure value. So jumping scross it will do you no good. Yes, the ambient temp sensor comes into play. If the PCM thinks that it's 40 below zero (which I think is the open circuit value) it will not engage the clutch.
