Note On Intermittents

If Code EO24 is stored as a history code, select parameter ED12. Lift drive wheels, place transmission in Drive and allow wheels to turn. Manipulate affected wiring while observing parameter ED12. If fault is induced, parameter ED12 will momentarily drop to zero MPH. Check intermittent opens or shorts to ground on circuits No. 400 and No. 401. Check terminal contact at VSS and at PCM connector.
