Engine Temperature Sensor
Use Chart 3 to determine calculated engine coolant temperature.
Example: If Channel 6 displays a code of 187 on Control head, calculated temperature according to Chart 3 is 77°F (25°C).
Note: The Engine temperature sensor is not equipped on all models (to be phased in). For vehicles without coolant temperature sensor (-G62-), view
