Whats the cel code for it? I'd try a new harness and connector or atleast try cleaning the one you have. a multimeter could come in use here if you wanna try testing your wires

Do they teach English and grammar in schools anymore? It's difficult to read and understand that nonsense writing.

If the code isn't going away by replacing the device it points to several times, then common sense says the ECU isn't recognizing the device as functioning or cannot see it.

Check the wiring from the IACV plug all the way back to the ECU with an OHM meter. It sounds as if you have a broken wire somewhere along the line.

I imagine that your friends write and speak like you do. Most of us will not understand you.


Could you please repeat what you said in everyday English?

Instead of blindly swapping parts, get out your ohmmeter and check the IACV. Page 375 in the EC section of the 1999 Nissan service manual says the 4 stepper motor windings should each measure approximately 30 ohms.

If the resistance readings are good, then start reading from page 369 for other troubleshooting steps.
