CEL 12 after disconnect S-AFC 2

Hi,

Now I am getting Check Engine Light code 12 (Air Flow sensor) after I pull out my S-AFC2.

Is there anywhere that I can make that CEL go away? I tried disconnecting the car battery for 15minutes and reconnect and start the car. But I still get the CEL 12.

Do I need to leave the battery disconnected longer, say, 1 hour?

Did you reconnect the airflow sensor wire after you removed the SAFC?
It will need to be spliced back together.
 

You mean connect the air flow sensor wire directly back to the stock ECU pin?

No, to install a SAFC you need to cut the airflow wire and connect it to 2 wires leading to the SAFC.
That is why you will need to locate and reconnect the ends of the airflow wire to make everything work again.
This is from the install instruction on VFAQ. This is the wire that you need to fix.

3) Air Flow Signal: Cut the Green wire with a blue stripe and Orange bands, corresponding to the connector hole as shown above (top row 3rd from left). This is the Air Flow signal wire. The AFC will intercept this wire and allow you to adjust the MAS signal to the ECU so leave enough wire from the connector so you can splice in.
