[QUOTE="Mark Kovalsky, post: 1223670, member: 1654"] The PCM looks at engine speed and turbine speed to measure slip across the converter. It's really easy to tell that it's locked when the PCM wants it unlocked. By the same method it can tell that the converter isn't locked when it should be. It will try several times to lock, and if it doesn't, it unlocks and sets a code. The PCM can detect the switch being there. There is an electrical short to ground test run on that wire. [/QUOTE]
