Well, you shouldn't need to replace the ECT...unless it's giving the dash or PCM bad info about the temp.
The IAT merely tells the pcm what temp the air coming into the motor is, that's about it.

Does your car have automatic climate control? If so there is an air temp sensor in from on the A/C condensor that reads outside temp and if it thinks it is hot out, no heat in auto mode.
