Code P024, Vehicle Speed Sensor (VSS) Circuit Problem: Action

WARNING: This page is about a different car, the 1995 Cadillac DeVille. However, it is still accessible from the selected car via links, so may be relevant.

PCM turns on MIL, and disables Torque Converter Clutch (TCC) and cruise control for the entire ignition cycle. PCM disables 3rd and 4th gears.

NOTE: Test number refers to number on diagnostic chart.

If Code P024 is current, fault is present and can directly be diagnosed. If Code P024 is stored as history, fault is intermittent. Use Code P075 to diagnose.
When spun by hand, VSS will generate a frequency of greater than zero hertz. If it does, PCM may be faulty. If it does not, check for opens and shorts in wires/sensor.
