DTC P024: Vehicle Speed Sensor (VSS) Circuit Problem: Description

The PCM receives unbuffered speed information from the vehicle speed sensor located in the transaxle assembly. If the PCM detects a vehicle speed of 5 MPH or less with a transaxle input speed (turbine speed) of 3000 RPM or greater for 1 second while in any forward gear, Code P024 is set. To avoid any erratic cruise control operation due to an intermittent problem, the cruise control system is disabled for the entire ignition cycle.
