Pcm Code P024 - Vehicle Speed Sensor (VSS) Circuit Problem: Notes

VSS is a permanent magnet pulse generator mounted in transaxle. PCM uses VSS input for TCC apply-and-release determinations, to select between RPM and throttle angle control of ISC, and as a test condition for many codes. PCM Code P024 sets when PCM detects zero MPH when engine RPM and TP sensor indicate that vehicle is moving.
