Beginning in 1993 the Europe/UK Accord 4-door was a different car, built in Swindon UK. Not sure if these sensors & systems are the same.

There's 2 fan switches and 2 coolant-temperature sensors.

Fan switch A is located in the thermostat housing. It switches the fans (both) when the engine is running. Pretty sure that works when the key is turned ON but the engine doesn't actually need to be running.

Fan switch B is located in the nozzle for the upper radiator hose, near the head. This one has authority to switch one of the fans, after the engine has been turned off. There's a timer to prevent the fan from running forever even if the switch-B is stuck.

"ECT sensor" Engine-Coolant-Temperature sensor is located roughly below the distributor. It has a plug with 2 wires. This sensor provides a coolant-temperature measurement for the ECM.

Lastly, there's another temperature sender near the ECT sensor. This one has only one wire and it provides the signal for the dashboard temperature gauge.

I know this was posted almost 9 years ago, but so very informative. Thank you, thank you, thank you. This was the bit of info that i so needed to help me figure out my coolant fan dilemma. It was the missing info that I needed. You are awesome! Now I can finish fixing my mom's car and get her fans operational again.
