1994 Honda Civic DX automatic: Does temperature censor regulate the cooling fan?

Asked by Royel Jun 04, 2014 at 02:22 PM about the 1994 Honda Civic DX Hatchback

Question type: Maintenance & Repair

My 1994 civic dx temperature gauge does not work. Car overheats. Gauge still shows
no temperature rise. Is the sensor bad? Does sensor in civic regulate the cooling fan?

I found below in this link: http://www.aa1car.com/library/coolant_sensors.htm

"* Operation of the electric cooling fan. The PCM will cycle the cooling fan on and off to
regulate engine cooling using input from the coolant sensor. This job is extremely
important to prevent engine overheating. Note: On some vehicles, a separate coolant
sensor or fan switch may be used for the cooling fan circuit only."

So question is, does temperate sensor regulate the fan in civic?

Your "thermostat" regulates the flow of water travelling through your engine impelled by the water pump circulating through radiator which dissipates heat, when you stop in traffic or leave the car in Park running and air is not flowing through radiator soon after you'll see/hear the electric fan kick on and its buzzing sound, that is your temperature sensor "sensing" a higher temperature than "normal" because vehicle is static = no air flow> thus the fan comes on to bring temp down. The cluster gauge is only "reading" a temperature: Cold, Normal, Hot from the sending unit. Have you checked fan fuses??? also cluster? https://www.youtube.com/watch?v=4LdU721UVF0 https://www.youtube.com/watch?v=DWmt6gorzUg https://www.youtube.com/watch?v=E1tjyKG2V3Q
