Temperature Gauge
The temperature gauge is located in the LCD display area and is a graphical image as opposed to the more traditionally recognized analog gauge. The base IPC uses a thermometer style image that moves upward as the engine temperature increases, changing color as the temperature reaches predetermined ranges. When the temperature is in the cold band, the thermometer color is blue. When the temperature is in the normal band, the thermometer color is gray and when the temperature is in the hot band, the thermometer color is red.
The optional IPC uses a more traditional gauge image with a single bar set horizontally across the gauge and moves vertically from bottom to top as the engine temperature increases.
The PCM uses the CHT sensor to measure the engine temperature. The IPC uses the engine coolant temperature message from the PCM to control the temperature gauge indication.
