Temperature Gauge
The temperature gauge displays the engine coolant temperature. Current flow through two coils moves the pointer of the gauge and is similar in operation to the fuel gauge. The engine coolant temperature sender sends resistance through CKT 35 (DK GRN) to pin 13 of the IP Cluster.The engine coolant temperature sender has low resistance at higher temperatures. The sender has a resistance of approximately 49.5 ohms at 123°C (260°F). The sender resistance increases at lower temperatures and is approximately 1305 ohms at 47°C (100°F). This causes the current through the sensor to increase as the coolant temperature increases and the temperature gauge pointer then moves toward the hot end of the gauge.
