Code 24, Vehicle Speed Sensor: Notes

Code will set if Codes 28, 56 and 91 are not set, buffered vehicle speed is less than 5 MPH, transaxle turbine speed is 3000 RPM or more and transaxle indicates a forward gear.

NOTE: Test numbers refer to numbers on diagnostic chart.

If code is current, fault is present and can be diagnosed directly. If code is stored as history, use Code 75 chart to diagnose intermittent fault.
VSS will generate a frequency of greater than zero hertz when wheel is spun by hand. If it does, PCM may be at fault. If it does not, check sires/sensor for opens and shorts.
