2006 Honda Civic Hybrid IPU Fan Speed Control Help Needed
I have a 2006 Honda Civic Hybrid.
The IPU fan seems to be running at high speed all the time except when the car is shut off ( key is not turned to ignition or the engine is not running)
How can I diagnose this?
I read online somewhere that the voltage, current and temperature together are used control / determine the speed of the fan.
Is this correct?
Am I looking for relays, resistors, temperature sensor(s), voltage controller, current controller, pwm controller?
And where is/are it/they located?
I bought and installed a battery pack grid charger for the ima battery and it seems to be working well.
I am just trying to see if I can resolve this one issue with the fan always running at high speed all the time the engine is running or the key is turned to ignition.
In the past it never seems to do that.
It would only run when needed then shut off - at least it appeared that way to me.
Any help you can provide would be greatly appreciated.
Thank you in advance for your help.
