Diagnostic Solutions: Engine Coolant Temperature Sensors ...

2013-06-14· For example, a 1996 engine might compare the data inputs from the IAT sensor and the ECT sensors to determine if the engine is starting from a cold-soak or a hot-soak condition. If both temperatures are within, let’s say, eight degrees of each other, the PCM ­assumes that the engine is starting from a cold-soak condition. This data allows the PCM to adjust the spark and fuel maps to start ...

Symptoms of a bad/failing engine coolant temperature sensor?

2011-10-16· Every time the engine would kill, the light would go out at that exact moment. Out of shear blind luck, I decided to replace one sensor, the engine coolant temp sensor(it may be the engine temp sensor in the runner, may make a difference). Its been fine for 7 or 8 years, maybe 40,000 miles, and i haven't changed anything but shocks since then.

Thermostat Problems - Will Affect Your Engines Performance

2020-11-19· The thermostat starts off at a closed position, when you start the engine. Consequently, helping the engine reach its proper operating temperature. While the engine is running the coolant temperature slowly rises. As a result, making the thermostat begin to open. The opening allows warmer coolant in the engine to flow into the radiator. In turn, the water pump pushes lower-temperature …

Engine Coolant Temperature Sensor (ECT)

In cold engine and an ambient temperature of 20 ºC the sensor resistance is between 2000Ω and 3000Ω. After the engine start, coolant temperature begins to rise. ECT gradually heats and its resistance reduces proportionately. At 90 ºC its resistance is in the range of 200Ω to 300Ω.

Engine Coolant Temperature Sensor (ECT)

A defect sensor can indicate a voltage of at cold engine and at warm engine, thus causing difficulties of starting a cold engine and a presence of rich fuel mixture when the engine is warm. This will not generate any fault codes (if the onboard controller is not programmed to detect voltage changes) since the sensor continues to operate within its design parameters. If such defect ...

Can a bad coolant temperature sensor cause car not to start?

2020-03-07· In order to receive an accurate reading of the most recent engine temperature, the ECU sends a regulated voltage to the coolant temperature sensor. The sensor then gives off some resistance depending on the temperature of the coolant. This is how the ECU can monitor temperature changes. From there, the ECU uses the reading that it gets to calculate the coolant temperature …
