This vacuum line 'T' had popped off the nipple coming out of the lower intake. Only takes about 1 second to fix. Just slip it back on an -WHALLA!!
Didn't want to bring this old topic up, but it could be the same problem as mine.
I do not see this on mine Pontiac Bonneville 1996 SE Engine VIN=K. Not in the same place at least. Is this 'T' something that came on later models or SSEis?
Anyway, I have P0107 and P0108 error codes. All the wires seem secure and in place. I did clean up the sensor. When I take out the sensor there are no changes in the operation of the engine. There are 5 volts coming to the sensor. I tried resetting, but the codes came back up.
I have GM# for this sensor = 16187556 (some places list it as AS49, some as AS59). I have found on ebay GM#9359409 (standard #AS155), and seller lists my car under the models it will fit. Do you guys think that will work (if I were to replace the sensor)? When I did search on AC Delco'* site with my VIN #, I did 213-796 which is AS155.
