You might want to consider providing a little more History concerning this vehicle. What was the original concern/problem you were attempting to correct? "Power"(12 volts)....to a Computer sensor could damage a Computer. Many Computer Sensors operate using a 5 volt reference from that Computer. Could you ID the name of the sensor in question? A wiring diagram can then be accessed to ID the circuit.

I am not familiar with a "heater sensor". What color are the wires and how many wires on this sensor?

Start by checking fuses which power up the ECU. Check left side of dash and check 15A ECU-IG Fuse. JB No. 1
Check under hood fuses there's only one 30amp fuse check it
