1.22 Inspecting the Exhaust Temperature Sensor

Test the continuity between connector terminals. If the reported temperature is normal, you only
have to check whether or not continuity exists. If no continuity is detected but your inspection
finds no problems with the exhaust temperature sensor itself, chances are that there is a contact
failure. When a contact failure is suspected, check the exhaust temperature. If the exhaust
temperature is OK, then open and visually inspect the catalyst mount.
For the temperature/resistance characteristics, see page 225 [Table7.3 List of resistance/
temperature characteristics of outdoor unit sensors].
