Generally, no. The basic cooling system is a thermostat, water pump, radiator, fan, and hoses. They run as a closed system, but with sensors in place so the rest of the engine can adapt. The only exception being the fan, which may be electrical, which uses the engine coolant temperature sensor to switch it on and off.
A bad thermostat can cause an overheat. A bad temp sensor can show an overheat when the temperature is normal.
Bad temp sensor, bad fan relay, blown fuse, bad fan motor, low coolant, clogged radiator, loose fan belt, the list goes on.
A bad engine temp sensor can do that.
Yes. A bad or failing temp sensor prevents the ECM from monitoring, and adjusting for, the engine temperature.
No.
Could be a bad fuse Could be a bad temp sensor Could be a bad relay
Bad temp sensor. Bad temp sensor.
more then likely it could be the temp, sending unit. or a bad wire to temp, sensor!!
temperature gauge not working can be caused by a bad temp sensor in engine, a bad gauge in dash, or a bad fuse
there can be up to 3 temp sensors on an engine. One for the dash guage, the second for the computer input and the third controls the electric cooling fan. If the obd system called a bad temp sensor, then it is the ECT SENSOR FOR THE COMPUTER.
could be a bad TPS throttle position sensor OR a bad IAT idle air control temp sensor.
I assume your asking what problems a bad IAT sensor will cause.... You may want to read ur questions before posting them... Very rare to see a bad IAT sensor on any car. They don't do much, unless you have a code for only a bad IAT, its not the problem. Simply measures underhood temp or the temp of the air after the air cleaner.
