Determines which cylinder is firing to establish injector synchronization and coil firing sequence in DIS systems. when the engine coolant temperature increases, the electrical resistance decreases and this also causes a voltage drop in the sensor). It all depends on what range you were in, so if you were checking the sensor immediately after a cold soak start up, you would know you are suppose to be in the cold range. Notice that the tables for the various platinum curves are for the standard 100 ohm @ 0°C sensor. 0 – 6 KOhm or 80°C approx. The internal resistance of the sensor is determined. This may all sound rather technical, but what it boils down to is this: The temperature sensor is constantly monitoring the fluctuations in the coolant resistance, allowing it to alert your vehicle dashboard when. In some newer car models, the coolant temperature should shut off your engine once it reaches a high enough temperature. Measure yours with a good calibrated meter and compare to the specs. The internal resistance of the battery increases, and it's capacity to produce high current on-demand decreases. Temperature Sensor VE. Sure looks like a functioning resistor to. The coolant temperature sensor helps keep the engine at its optimal operation temperature and prevents it from overheating. The Engine Coolant Temperature (ECT) sensor resistance decreases as the coolant temperature increases as shown in this graph of the ECM coolant sensor. Temperature reduce -> resistance increase. The car's temperature gauge or temperature warning light is controlled by the computer which relies on the readings of the coolant sensor. If the ECT sensor’s wiring connector is damaged, it can produce a high resistance and cause the PCM to supply a richer-than-normal fuel mixture. From this signal, the ECU decides the amount of fuel to be injected into the combustion chamber and the rate at which the spark should be provided to the air-fuel mixture.
