How do you test the coolant temperature sensor valve on 97 Toyota Camry LE 2.2L 4cyl?
take resistance reading between the leads
What does the code PO118 mean on a 2001chevy cavalier?
high resistance coolant temperature sensor, is it overheating,air in coolant pipe at sensor, or bad sensor,
How coolant level sensor works?
A Coolant Level Sensor is like a multimeter which measures resistance of a certain amount of water. Water has conductive minerals in it therefore conducts electricity. A certain amount of water has a certain resistance to electricity. Fixing this voltage at, for clarity's sake, 12.0v, we can change the resistance of the conductor carrying this 12v by adding more water (and the minerals which conduct in it), or taking water away. like a fuel guage, At a certain resistance, the sensor will give off a certain reading. The fuel guage uses the change in this reading to move a needle, the coolant temp sensor uses this reading to trigger events in the cars ECU (Electronic Control Unit) or BCM (Body Control Module). The ECU or BCM will then light the dashboard warning for the Coolant Low Warning and log A DEC (Diagnostic Error Code) and probably also flag the CHECK ENGINE LIGHT on your dash. When the coolant is topped up again, the coolant sensor sends a different signal as it sees a different resistance, and turns off the dash light(s). Hope this helps!
Why does the needle on the coolant temperature gauge of a 1995 Saturn SL stay on the C?
The guage on the dash uses the ONE wire sensor... This is located in the block near the drivers side. Eric First check to see if you have coolant in the radiator. If there is no coolant you will not get any reading from the temperature sensor. If there is coolant then change the temperature sensor.
What is diagnostic code P0118 for Dodge Caravan?
Engine Coolant Temperature Circuit High Input 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. The PCM monitors voltage drop to determine coolant temperature. If the ECT reads less than freezing temp. when engine has been running for more than a few minutes, the PCM determines a circuit fault and sets this code. Or if the PCM determines the sensor resistance is out of specs, this code is set.
Can a coolant temp sensor on a 95 Jeep Cherokee go bad and send a false reading?
Yes, that is a possibility. A sensor can fail in many ways.
1988 camaro 2.8 were is the fan temp sensor located?
There is not a separate cooling fan sensor, it controlled by the ECM which get it's reading from the ECT (engine coolant temp sensor)
What is the ac pressure sensor resistance reading shoul be 96 Pontiac sun fire?
i like carrots do you
2000 Ford Escort ZX2 temperature gauge gets no reading Replaced temperature sensor radiator full of coolant Any Ideas?
Be careful there is a temperature coolant switch mounted next to the thermostat housing. I thought this was the sensor and replaced it by mistake. There is another sensor.
What do you check if your cooling fans are not coming on?
is the coolant temperature sensor giving a correct reading to the computer? Is the fan getting power?

Why would the low coolant light stay on in a 98 ford tourus v6?
Bad coolant sensor or faulty wiring to the sensor.
