2002 accord ex coupe 2.3l

recently had a check engine light(p1519) pop up along with idle surging. From what i have read, that code shows there is a electrical issue with the idle air control valve. i have also read it could be a power or ground issue with the main relay or ECU. or even the solenoid inside the iacv.

i read where people were using multimeters checking voltages and continuity. what i did was disconnect the 3 pin connector harness and took a test light and placed it in the harness where the power is. and it lit up fine. so then i took a paper clip and placed it where the ground is, connected the test light to that and poked it back into the power part of the 3 pin connector. still lit up.

is it safe to say the issue is more than likely the iacv and not any damaged wires or electrical issues going through the car?

I am just trying to avoid throwing parts at it, however, i would rather replace the iacv than try to find bad wiring and fix that. i just recently spent a good chunk of cash doing the timing belt and replacing the EGR.

input would be appreciated.

You have the 3 pin iacv and I'm not sure how to test that as with the 2 pin iacv you just test for ohms across the terminals and it should fall between 8-15 ohms.

Be that as it may it's not often that the issue is anything other than the iacv when you throw a code for it.

checking the ohms was going to be my next step, i just need to get a multimeter from my dad. made me feel better that i was able to get the test light to light up. so i assume i get power and i can ground. i feel like that should rule out a faulty harness or damaged wire
