Input and advice needed!

I was advised to remove the MAF harness from the MAF and see if I could get other codes to pop up besides the O2 sensor codes. Codes P0102 and P0112 came up, and not the O2 sensor codes. Sounds like my MAF has gone bad.

Hi,

Those two Codes are exactly what you Should Get when disconnecting the MAF, that would not be abnormal.

It reports an Open Circuit which indicates that there is no MAF hooked to the System. The MAF would definitely be Bad if you had it connected and still got those two codes.

You may still have an underfunctioning MAF, but those Codes alone don't justify replacement, especially at $200+. Try to drive the Car a day or so and see how it behaves...

PS Was this Test with the Car running? The O² Sensors have to be up to Temp to test them.

MNBoxster yes the car was running when I had the MAF disconnected. I ran it for about 10 minutes without it the O2 codes never came on even when I revved the engine and restarted it. The moment I went to move the car out of the driveway the P0102 and P0112 codes came on. I would think that if it was really the O2 sensors doing then shouldn't those codes have come on along with the open circuit codes? I connected the harness to the MAF and put everything back together for the night,its too dark to continue to troubleshoot.
