Note On Intermittents

If Code P060 is stored as history code, select PCM data PD72 and manipulate harness while observing status of switch. If switch changes status while wiring is being manipulated, repair intermittent connections. If no trouble is found, code could have been induced if transaxle was inadvertently put into Neutral while cruise control is engaged.
