The engine coolant temperature (ECT) sensor is a thermistor screwed into a coolant passage in the cylinder head. Sensor resistance is high when coolant temperature is low and resistance drops when coolant temperature increases. The powertrain control module (PCM) provides a 5 volt reference and a ground to the sensor. Reach down and disconnect the temperature sensor's electrical connection. Use a metal pick to remove the sensor's locking clip. Be careful not to drop it into the engine. Using a pair of long nose pliers, grasp the MINI R56 coolant temperature sensor and pull it out of the thermostat. Reach into the sensor opening and remove the old sealing o-ring.

Sensor could be shorted or just a bad sensor. Test the sensor for continuity and check the connector for the propper voltage. I think it should have 5 Volts. Coolant for Older Cars. Since coolant technology has evolved so much in the last few decades, if you own an older vehicle you need a formula with a special additive to allow chemistries old and new to work together. Multi-Vehicle Antifreeze/Coolant helps extend the life of higher mileage vehicles with the additive AlugardPlus®. The engine coolant temperature sensor is temperature-variable.

#2 · Oct 9, 2006 You have to take the airbox off to access the ECT. Once the airbox is off, you still won't be able to see it. You'll see a rectangular black plastic wiring harness and you can feel the ECT if you slide your hand under the wiring harness. It's a devil of a hard place to get to. • base/auto • Comptech air filter • D Drag68Bird. The Engine Control Module (ECM) uses the CTS' values to monitor the engine's temperature and in turn, can regulate it accurately. Different temperatures require different air/fuel mixtures.

3. Drain the engine coolant .. 4. Remove the battery and battery tray.. 5. Disconnect the ECT sensor No.1 connector. 6. Remove the ECT sensor No.1.. 7. Place the ECT sensor No.1 in water with a thermometer, and heat the water gradually. 8. Measure the resistance between ECT sensor No.1 terminals A and B. If not as specified, replace the ECT. Higher signals correlate to colder temperatures and higher fuel densities. The computer uses the signals to calculate the fuel’s density and adjusts various processes in the fuel system and engine. The fuel temperature sensor helps the PCM adjust the air-fuel ratio to a very fine degree. This helps the engine get the right amount of fuel it.

P0118 Engine Coolant Temperature Sensor 1 Circuit High 2001 pt cruiser base 2.4L automatic. The Heat sensor has been replaced 3 times with after market parts not OEM parts. The car drives fine for 40 minutes with the heat temperature on dash board gauge working if car has sat 12 hours. 3 Wire Coolant Temperature Sensor Wiring Diagram. The two wires, a "5-volt reference", and a "ground wire" go to the ECU, and the third wire "Earth Signal Wire for Temperature Gauge" goes to the cluster-mounted temperature gauge by providing an earth signal to the temperature gauge. In three wire coolant temperature sensors, the ECU.
