sensor circuit is open or shorted
HINT:
When DTC P2742 is output and the Techstream output is 150°C (302°F) or more, there is a short circuit.
When DTC P2743 is output and the Techstream output is -40°C (-40°F), there is an open circuit.
Check the temperature displayed on the Techstream in order to check if a malfunction exists.
