I ran sea foam thru my car last week and now I have 2 codes P1031 - Air/Fuel Ratio Sensor Meter, and P1148. Where is the A/F Sensor located. I am wondering if I might of left it un plugged when I changed my spark plugs?

Any help is greatful.

 

its behind the intake box beofre the z/g tube. AKA MAF sensor could probably use some cleaning.

 

are you talking about the MAF sensor or the o2 sensors? If you're looking for the o2 sensors, there are four of them - 2 on each of the catalytic converters. one is up high near the header, the other is at the bottom near the y-pipe.

 

I am not sure. Half of what I fould directed me to the MAF, and the other half said the O2 sensor. I am going to try and clean the MAF and see if the takes care of the problem.

 

Forgot to say thank you. With out this forum and everybodies help, I would be running around looking like a chicken with his head cut off.
