Yes, thanks for information. I did check resistance at motor which was 25 ohms on all checks. I add that code 47 was included on check light codes, most of all these codes came on after alternator replacement and low fuel light stays on at any level. These all problems came on.

Hello again,

In the diagrams down below I have included the general on vehicle inspection guide for your vehicle's IAC from the vehicle manufacturer. Please go through this guide, see if the IAC is working properly, and if not, please get back to us with what it is specifically doing. We can go from there.

Thanks,
Alex
