That's exactly what happens when you short the ecu sensor ground with the heater circuit. There is a little trace on the lower left corner of the ecu that all the sensors ground through. This has probably been cooked. Its an easy fix. Just pop it open and repair the trace. Unless its cooked too much lol.
