High Idle After Warm Up
I have 1989 bone stock Civic with a D15B1 engine with Dual Point Fuel Injection(DPFI). Once the engine warms up, the idle does not drop; for the ECU will not disengage the Idle Air Control Valve(IACV). The idle will drop to near normal when I unplug the IACV, but that is no way to run my car. I think it might be the coolant temperature sensor; however, I do not know the specified range of resistance it should be within. If any knows this valuable information, it would be very helpful since I am having trouble finding it elsewhere on the internet. Thanks for the help.

Re: High Idle After Warm Up
I found some information regarding the coolant temperature sensor which states it should be between 200 - 400 Ohms at operating temperature. The RED/WHT wire is a five volt reference wire, and the GRN/WHT wire is a ground; just in case anybody is interested. So everything checks out which leaves me back at square one. Once again, thanks for the help.

Re: High Idle After Warm Up
Fast idle valve, EACV and TPS are always suspects according to my Euro manual on Efi Honda motors.
