Question about 2006 Chrysler 300
I have a 2006 Chrysler 300 base model 2.7L V6. I already replaced the sensor and was able to borrow an instrument cluster and it still didn't work. What else can it be? Please help, don't know what else can be wrong.

if they arent working i would suspect a loose connection to the computer module or, a problem with the computer try scanning for any codes that there may be

have you got a dimmer switch on your model to dim the dash lights. if you have it may be faulty. link the cables together if the lights work the switch is faulty. if you have not got a dimmer switch
your printed circuit on the back of the dash may be faulty or the plug in the back of the dash is not pushed all the way in. hope this helps

Take your car to the nearest auto parts store and ask them to read and erase your trouble codes. As soon as you throw another code get them to read it again to verify which code is alerting you. Remember that just replacing a part is not always a solution. A egr is not too expensive and easily changed by someone handy. Buy a haynes repair manual for around $25. It's a good investment and will walk you through most repairs. It will also give you a basic understanding of what could be wrong with your car so that you will npt be taken advantage of by an unscrupulous mechanic .

The coolant temperature gauge sensor is a temperature-variable resistor, or thermistor. As coolant temperature increases, the resistance of the sensor decreases or decreases, depending on the type of sensor.
A1 and A2 platforms use a different type of circuit that A3 vehicles. On A1 and A2 vehicles, the circuit is a "resistance to ground" type. A3 vehicles use a "variable voltage" type, where a voltage is supplied to the sensor. Because of the circuitry design on A3 vehicles, testing of the coolant temperature gauge is limited.
The engine coolant temperature gauge uses a heat sensitive sending unit to transmit an electrical signal to the gauge. The sending unit is a heat sensitive variable resistor that is located on or near to the cylinder head and threads into an engine coolant passage. The sensors are a Negative Temperature Coefficient (NTC) type. As the temperature increases, the electrical resistance of the sensor decreases. As the coolant temperature changes, so does the resistance of the sensor. The gauge is calibrated within the operating range of the sensor and interprets the resistance value to display the coolant temperature.
Beginning with model year 1994, the engine coolant gauge and the Engine Control Module (ECM) temperature sensors were combined into one sensor with 4 terminals. The basic operation remains the same in that their resistance decreases as the coolant temperature increases, however the actual resistance values of the 2 sensor circuits are different. The electrical connector of the 4-wire terminal sensor ( 1 and 2 ) is keyed to prevent improper connection of the sensor's electrical circuit.
