Hey guys i have a 2000 civic si i was curious if the tempurature switch will throw a check engine light code? There is 3 sensors in total, 1 being for the fan to work and the other is coolant temperature that has 3 wires running to it. I know those have codes but I was curious if the tempurature swtich below the distributor that has one wire going to the gauge cluster will throw a code if bad. Thanks!

No, the gauge in the cluster just won't work. But I've been wrong before......

What CEL code(s) is thrown?

The only codes thrown are o2 sensors... But i was asking because my car will go to 3 quarters on the hot and cold gauge and go back down... I dont think the car is really heating up... Took it to 2 shops and no luck

sounds like crappy shops.

The temperature sending thermistor is typically a single wire sensor. I'm not sure where it is on a b16 but it is under the dizzy on d series.

You can test it with a volt ohm meter.

However i think you may havea fan issue or thermostat issue.

Or air in the cooling system. Might just need a proper cooling system bleed.

Could also be a sticky thermostat. When was it last replaced?
