Engine Block: FLEXPLATE: Description
WARNING: This page is about a different variant/trim than selected.
The flex plate is fastened to the crankshaft and can only be installed one way. The crankshaft has a dowel locating pin that is used to align the magnetic tone wheel and the counter weight. The stamped-steel flex plate has a segment ring to provide engine speed and crankshaft position information to the Power Control Module (PCM). The crankshaft position sensor is mounted next to the segment ring and sends electrical pulses to the PCM.
