2001 Sentra 2.0

I have been having probs with my car lately, stalling when I slow down to stop or make turn, hiccuping while driving, as though its running out of gas (it's not!) I brought it in to get some codes and they were ABSL pressure sensor P0105, 02 sensor P0134. My bro thinks it's the O2 sensor and I would like a 2nd opinion befor I give him the go ahead to change it, and which one would he change 1 or 2? (befor or after comppressor) Pleeeeeeeeease help!

it is unlikely it is the O2 sensor. When an O2 sensor fails it usually does not cause such problems (at least on 2000 and newer cars). My wifes sunfire has had a faulty O2 sensor (rear) for 2 years and not a prob. My mechanic (reliable one) tells me that all 2000 (or there abouts) and newer cars *generally* have preset defaults that it will run to when an o2 sensor fails.

Therefore you should have a check engine light on if its an o2 sensor and you shouldnt notice a large diff in fuel consumption as the computer should warn you about the o2 and then compensate with default mixtures etc.

Sounds like its the 2nd option and not the o2 sensor but thats just my opinion

Service engine soon light is on and....fuel consumption has increased noticeably. Tried the O2 thing, and so far so good! Thanks anyway!

yeah id say that was your problem. im not sure what sir smiley was talking about but your symptoms suggest 02 sensor to me...
