Hi. I'd like to preface this by saying that I realize that there are a lot of diagnostics that should be done to diagnose and pinpoint the problem, and I know that throwing parts at it is not the right way to go about fixing this.
Unfortunately I don't have the time. I already have a new o2 sensor (upstream) that I can't return and I don't mind throwing parts at it in an attempt to fix it quickly given my current situation.
I realize this isn't the smart way to go about it, call me stupid, I don't care, I just don't need a lecture on how I'm not following proper procedures and how I might be wasting money by throwing parts at it before I've done a thorough diagnostics routine on it etc. I totally get it. Nornally I would do just that.
I don't have the time right now and I'm in a bind. I am very limited to how long I have to work on it in its current location and in my current situation, and so I'm asking for help.
As I mentioned, I already have a new o2 sensor for it on my shelf.
Problem. P0131 and 0171
My half-a$$ed plan is to check for a wiring problem to the sensor given the lack of voltage to it.
I just need to know if the sensor may be bad or if the wiring is bad before I attempt to remove it because I know that replacing it is going to be a nightmare and I'm going to ruin the existing sensor while attempting to remove it.
I just hope I can get the old one out in the limited time I have.
I'm not sure what I should expect when I check the wiring to it. Should I have a constant 12v to it?
I've already checked for vacuum leaks, checked for exhaust leaks before the sensors, and didn't find any.
With the attached snapshot of the live sensor data, the top graph is the downstream sensor data. It changes when I rev the engine.
The bottom graph is the upstream and the voltage to it is between 0.0 up to 0.07 so basically no change when increasing RPMs.
The engine was warned up to normal operating temp before running scanner tests.
I guess what I'm asking is if you were in a bind, and if this was your situation, what would you do to check out the problem starting with the easiest, fastest things to check to determine if it is the O2 sensor that's bad? Not because I'm too lazy to research it, learn about it and spend the time to do it right, but because I don't have that luxury this time.
I sincerely appreciate any guidance and your understanding. Thank You
