Alright, yeterday, the car was running fine.

I get in today and notice a choppy idles, and a CEL. Turn on the logger and ger a "12-Airflow Sensor" message. I look over at the AFC and there is no display...CEL solved.

I pull apart the pass side console and slide the ECU out and get out my multimeter. I can read ~12v (slightly more) at the power connection, ECU side of the harness, and AFC side of the harness when it is plugged in. I see 3v on the ground at the harness connector. :confused:

So, is it a connection issue, or is the AFC shitting the bed?



EDIT: Possibly fixed...will update if it isn't :thumb:
 
Again, lets not assume.

The connector inside the AFC had seperated from the motherboard.

Problem solved.

Edit: Just noticed "check all your vamps". Anyone who uses vampire taps on a critical component as this should be beaten about the head and neck with a sack of pennies.

Dude, thanks so much, i spooled the car hard, and the S-AFC fell out of the dash and the wire unpluged from the mother board so i just took it apart and everything is fine.
