How to Check the Temperature Control Sensor on a 1997 Chrysler Concorde 3 5 Engine
The Chrysler Concorde, also known as the sister car to the more popular Dodge Intrepid, came from the factory with two V-6 engine options; a 2.7-liter engine and a more-powerful 3.5-liter engine. Of the two engines, the 3.5-liter engine was noted for its increased reliability over the smaller engine, which was prone to oil sludge problems. To help control and monitor the engine temperature, the 3.5-liter engine contains a coolant temperature sensor, located on the thermostat housing at the front of the engine.
Instructions
- 1
Start the engine and allow it warm to operating temperature, which is 200-degrees Fahrenheit.
2Locate the coolant temperature sensor on the top of the thermostat housing. Its mounted vertically and has two wires protruding from its base.
3Disconnect the coolant temperature sensors two-wire electrical connector. Measure the resistance across the sensors two terminals with a digital multimeter; the specified value is 700 to 1,000 Ohms.
4Let the engine cool down for three to four hours until the coolant is at room temperature. Measure the resistance again across the terminals with a digital multimeter. The resistance at 70-degrees Fahrenheit should be between 7,000 and 13,000 Ohms. If the resistance falls outside either of the hot or cold values, the sensor must be replaced.
5Measure the resistance across the pin terminals on the sensors electrical connector. If the resistance is greater than 1 Ohm, replace the sensors connector.

How do I Locate and Repair a Ford F 150 Temperature Sensor
Depending on the year, make and model of your Ford F-150, the vehicle may have a temperature sensor and a sender: If the truck as a gauge, it will have both; if not, it will only have the sensor. The sender may be located in the radiator or near the thermostat housing. It reads and sends the temperature of the water/antifreeze mixture to the gauge. The sensor also sends the temperature of the water/antifreeze mixture to the computer, so that the computer can make adjustments in timing, air and fuel mixture, and other adjustments needed by the truck to run ai its optimum performance levels and get the best fuel mileage.
Instructions
- 1
Open the hood of the F-150.
2Inspect the front, center of the engine and locate the rear of the thermostat housing. Find the thermostat housing by following the top radiator hose from the radiator to the block.
3Place your hand on the sensor that is mounted in the intake manifold, just behind the thermostat housing. The sensor has a round plug, which has wires coming from the wiring harness plugged into it. If you remove it, the base will look like a large bolt that screws into the intake manifold.
4Push the plastic harness connector out and lift the wiring harness plug out of the sensor. Using the socket, unscrew the coolant temperature sensor from the intake manifold.
5Wipe a thin layer of anti-seize compound on the threads of the coolant temperature sensor. Screw the sensor into the intake manifold. Plug the wiring harness back in.
