What to do if your temperature sensor is out of specs?
If the scan tool reads an illogical temperature, check the resistance of the temperature sensor. If it is out of specs, replace it. If it is in specifications, unplug the sensor and, using a fused jumper wire, jumper the two terminals of the connector together. The temperature reading should now be maxed out to above 250 degrees F.
How can I tell if my coolant temperature sensor is bad?
To diagnose the coolant temperature sensor, you need a repair manual for your car model to find what measurement values you should expect from the coolant temperature sensor. Connect an OBD2 Scanner and look for related trouble codes. Check the live data to see the temperature from the sensor.
Which is the correct description of a temperature sensor?
A Temperature Sensor, as the name suggests, senses the temperature i.e. it measures the changes in the temperature. In a Temperature Sensor, the changes in the Temperature correspond to change in its physical property like resistance or voltage.
What’s the name of the coolant temperature sensor?
Coolant temperature sensors are also known as engine coolant temperature sensors or ECT sensors. The principle working of this sensor involves the use of an electrical resistance which measures the temperature of the coolant.
Where can I find a temperature sensor tutorial?

About: All-original DIY electronics kits – Adafruit Industries is a New York City based company that sells kits and parts for original, open source hardware electronics projects featured on www.adafruit.com as well a… More About adafruit » What is a temperature sensor?
How does a temperature sensor work with a tmp36?
Using the TMP36 is easy, simply connect the left pin to power (2.7-5.5V) and the right pin to ground. Then the middle pin will have an analog voltage that is directly proportional (linear) to the temperature. The analog voltage is independent of the power supply.
Can a check engine light code be troublesome?
Oxygen Sensors, otherwise referred to as O2 Sensors, and their related check engine light codes, can be troublesome at the very best! Today we discuss the design and function of these sensors, and some of the pitfalls encountered during the diagnosis of their related fault codes.
What should the voltage be on a temperature sensor?
If you’ve got a TMP36 and its about room temperature (25 degrees C), the voltage should be about 0.75V. Note that if you’re using a LM35, the voltage will be 0.25V
Where is the coolant temperature sensor on a car?
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.
Which is p0118 engine coolant temperature sensor high input?
P0340 tps high voltage P0118 engine coolant sensor high voltage P0108 map high voltage P0351 coil primary circuit (no idea what that means..) P0113 IAT high volt… 2001 Saturn SC 1.9 4cyl. 120,000mi. P0118 CTS, P0507 ERGvalve, P0301 misfire #1.
What happens if the coolant sensor is high?
So, if the coolant sensor has a poor connection (high resistance) at the wiring connector, the computer will see a higher voltage signal and would supply a richer-than-normal fuel mixture based on the resistance of the coolant sensor and set one of the ECT diagnostic trouble codes (DTC).
What kind of temp sensor does Saturn use?
However, its lineup continues to be sold privately in the retail market. The Saturn lineup includes the S-series, the L-series, Vue, Ion, Sky and Aura. Underneath the hood of Saturn vehicles, the coolant temperature sensor helps monitor and regulate the engine temperature.
When to replace the temp sensor on your car?
The temperature sensor alerts the engine control computer when the engine is overheating. Replacing the temperature sensor is strongly recommended if you suspect the sensor is damaged. Park your vehicle in a safe location on even ground.
Where is the coolant sensor on my car?
Look just below where the radiator hose connects to the engine block and you should see the sensor. Identify the engine coolant temperature sensor as a black and copper-colored prong sticking out of the engine block. The sensor will also be attached to two wires.
How do you remove a temp sensor from an expansion tank?
First, remove the cap from the expansion tank and then tighten it the way it was before. Next, Richpin shows the procedure for locating the temp sensor. Then, remove the connector from the sensor. Afterwards, Richpin shows how to examine the sensor parts and the connector.
