Code P024, Vehicle Speed Sensor (VSS) Circuit Problem: Notes
WARNING: This page is about a different car, the 1995 Cadillac Eldorado. However, it is still accessible from the selected car via links, so may be relevant.
VSS is a permanent magnet pulse generator mounted in transaxle. PCM receives unbuffered speed information VSS. Code P024 sets if PCM detects vehicle speed of 5 MPH or less with transaxle input speed (turbine speed) of 3000 RPM or greater for one second while in any forward gear. To avoid any erratic cruise control operation due to an intermittent problem, cruise control system is disabled for the entire ignition cycle.
