2000 Chrysler Town and Country sensor

You left something unplugged or you turned the ignition switch on while it was unplugged. There's going to be a diagnostic fault code in the Engine Computer. Chrysler makes reading them yourself easier than any other manufacturer. Cycle the ignition switch three times from "off" to "run" without cranking the engine, leave it in "run", then watch the code numbers appear in the odometer display. Holler back with those numbers.
