Test Equipment: Notes

  1. All sensor and ignition timing signals of Porsche vehicles can only be checked with engine testers recommended by Porsche. Since tester connections are made on vehicles differently depending on make of tester, always refer to supplier's instructions for correct test connections.
  2. Since curve shape and signal voltage ratings for inductive sensors are not always included in engine tester manuals, this article will supply you with some information for making correct connections.
