Ok, you have three sensors on this engine that work together to manage the temperature reading that are sent to the gauge. i recommend checking all three to be safe. i will list the sensors and, locations below.

1. Coolant temperature sensor- Under hood, driver side, upper engine area, above transmission bell housing, mounted in driver side end of intake manifold.

2. Engine Temperature sensor- Under hood, driver side, upper engine area, mounted on rear cylinder head

3. Temperature switch.- Under hood, center, lower engine area, above oil filter, rear of coolant temperature sensor, mounted in engine block
