Narrative:
After being cleared to takeoff runway xxr we begin to execute a short field takeoff with the student flying the plane. All indications were in the green during takeoff roll and rotation. Upon reaching about 400 MSL cht #3 showed a red indication with a max of 500 degrees and was accompanied by vibrations and a burning smell which dissuaded me from believing it was a faulty sensor. I took controls at this point. I had just switched frequencies to ZZZ departure and I immediately notified them that I would like to return to ZZZ for landing. Once on frequency with tower I told them i wished to land full stop but I did not declare an emergency. By this time i made the decision to attempt to climb to ZZZ1 as I did not want an engine failure at 400 AGL. I was able to climb to ZZZ1 and fly a mostly normal pattern and land on runway xxr. While on final I went power idle and the cht went to a reading of about 100 degrees which was now significantly lower than the other cht temperatures. We taxied back and wrote up the plane to be assessed by maintenance.

Narrative: After being cleared to takeoff Runway XXR we begin to execute a short field takeoff with the student flying the plane. All indications were in the green during takeoff roll and rotation. Upon reaching about 400 MSL CHT #3 showed a red indication with a max of 500 degrees and was accompanied by vibrations and a burning smell which dissuaded me from believing it was a faulty sensor. I took controls at this point. I had just switched frequencies to ZZZ departure and I immediately notified them that I would like to return to ZZZ for landing. Once on frequency with Tower I told them i wished to land full stop but I did not declare an emergency. By this time i made the decision to attempt to climb to ZZZ1 as I did not want an engine failure at 400 AGL. I was able to climb to ZZZ1 and fly a mostly normal pattern and land on Runway XXR. While on final I went power idle and the CHT went to a reading of about 100 degrees which was now significantly lower than the other CHT temperatures. We taxied back and wrote up the plane to be assessed by Maintenance.
