P258BVacuum Pump Control Circuit A Range/Performance
The vacuum pump control circuit is electrically intact, but the pump response does not match the model — pump runs longer than expected to reach setpoint, current draw rises (mechanically tight) or vacuum does not build at all. Aged motor brushes, dry vanes or a leaking line are typical causes.
