If you are talking about the water temp switch on the radiator, pull of the wiring plug and bridge the two connection with a paper clip or a small piece of wire.
If the cooling fan works as normal the temp switch is faulty and needs replacing.
I hope this helps.
In rocket test bench, how to measure the temperature. Where is the temperature sensor place in rocket test bench.
go to auto zone and have them run a computer test on your car
Test the relay and the temperature sensor.
You can "test " the sensor using a DVOM ( digital volt ohm meter) if you have a manual that has the spec, also helps to have an inferred temperature gun to confirm the temp at the sensor.
If it is a 1997 S10 4.3, with the engine running, remove the fuel pump relay, if the engines stops running, the oil pressure sensor is bad.
Potenially a bad temperature sensor or bad contact on the wire connector. Test for set voltage resistance according to temperature.
IAT sensor and or related wiring, you need elec troubleshooting tools to test. Search intake air temperature sensor inspection for procedures/tools req'd.
cylinder 4 misfire detected code p0304 will not pass emissions test want do I need?
Depends on the make of the vehicle. Ford=Transmission Fluid Temperature sensor out of self-test range. Hyundai=Oil Temperature sensor abnormal Subaru=Engine Torque Control signal 1 circuit malfunction
The only fix is to replace it. If you are mechanicly inclined, this is a doable deal. Before you replace the sensor you should check the wiring for resistance you can use a volt/ohms meter (vom) and test the continuity of the wiring to the sensor.
take it to parts America have them read the codes that's begining signs of a vss vehicle speed sensor going , or tr sensor transmission range sensor
To test the Engine Coolant Temperature (ECT) sensor on a 2.2L Ecotec engine, first, locate the sensor, which is usually found near the thermostat housing. Use a multimeter to check the resistance of the sensor at various temperatures, comparing your readings to the manufacturer's specifications. Additionally, you can monitor the ECT sensor's output voltage using a scan tool or multimeter while the engine runs to ensure it changes appropriately with temperature. If the readings are outside the specified range, the sensor may need replacement.
