What problems can a bad coolant temperature sensor cause?

A faulty sensor can cause the fuel mixture to adjust. This causes the engine to shake or vibrate when the vehicle is at low speed and can even bring about strange behaviors, power losses, etc. Engines are highly sensitive, especially to inappropriate air-fuel mixtures at idle. via

What happens if coolant temperature sensor is bad?

A faulty signal from the coolant temperature sensor can either bring in lower or higher amounts of fuel. In the latter case, extra fuel will stay unburnt and remain in the combustion chamber. This unburnt fuel ends up in the exhaust of your car. It will cause black smoke to come out of your car's muffler. via

How do you test a PTC thermistor?

Connect the multimeter terminals to the thermistor leads. Polarity is not an issue here. Now heat the thermistor by moving your heated soldering iron tip to it. Now you can see the multimeter reading smoothly increases or decreases depending on whether the thermistor under test is PTC or NTC. via

Can thermostat affect idle?

Can Bad Thermostat Cause Rough Idle? In the case of a stuck thermostat, the engine may not reach normal operating temperature, and it may idle faster than it should, but it should still idle smoothly, unless there is an additional problem. Cold engines idle cars more quickly. via

Why does my temperature gauge stay on hot?

Common reasons for this to happen:

Broken Temp Gauge: If the temperature gauge is maxed out but the engine isn't actually hot, then the problem may be a broken temperature gauge. The needle may be stuck in the hot range (this can happen after overheating the engine), or a stepper gear in the gauge may be damaged. via
