Question about Cars & Trucks
USA answer, not in usa , ignore my post or post country?
it can only be 3 problems, alldata.com covers the simple tests.
1: bad sender (if scan tool shows ECT reads right, its not this)
2: bad wires (conns) ECU/pcm to gauge.
factory FSM or alldata.com.
here is your type system, its no longer independent like in older years
The coolant temperature information is conveyed to the instrument panel, through the PCM, from the Engine Coolant Temperature (ECT) gauge sending unit. To test the gauge sending unit, first test the gauge operation to make sure the problem is not in the gauge or gauge wiring.
my guess ? bad connection to I/P gauge cluster (rear)
do this only after scanning (any scan tool works) the ECU OBD2 port to see if temperature is normal at the ECT but Guage lies.
that is it. only testing wires an gauge, works from this point.

The sensor is right next to the heater hose outlet on the front passenger side of intake manifold. It is very small with an oval shaped connector going to it. I have the same engine.

You might need a new ECT - engine coolant temperature sensor. If it's not reading the correct coolant temperature it's not going to tell the fan to turn on when it should.
Is the check engine light illuminated? I'd bet the ECT needs replacement.

Look for a loose connection to the temperature sender unit on the motor.
If all connections OK, you may need a new temp sender unit.
