    Thanks. That is what I thought it meant. To check continuity from point to point. (source to sink) EF-37 highlights pin 17 to negative ground at the battery. It apparently goes to a common ground...

    Can someone tell me how to conduct a circuit test? Specifically EF-37 for the TPS idle. What results am I looking for?
