My scanner finally came in today. I had it scanned about a month ago and I had P0133 and P0153. Today when I scanned it, only P0133 was in the computer. I ran some tests and bank 1 sensor 1 o2 sensor came up with .460 volts. So is my o2 sensor in dire need to be replaced or do I have to start looking at other things?

Also Catalyst Rear to Front Switch Ratio Bank 2 (CATRAT2) is 1023.98 meanwhile CATRAT1 is .8 is this very bad? What does it even mean???

Evaporative Maximum Vapor Generation Rise Limit Phase 4 (EVAPRISEL4) is -64.00 inches of water with minimum of 2"

There is misfire on cylinders 7 and 8 which is ok since it's a V6 but, for cylinders 9 and 10 it says pass, whats with that?

 

codes for missing cylinders says you coded the wrong engine into the unit or the unit is bad.
What do you mean you ran tests and got .46 V on O2? You should be running dynamic, real time test and watch th eO2's switch above and below .45 V. If you got a steady.46 V, I would suspect a bad sensor 1st.

I don't understand a switch ratio number. Sorry, I'm sure it means something but my OBD-I doesn't use that terminology.

 

Speaking of Scanners/Code Readers....
Where can I read more about them and obtain one along with and additional material I might need.?.

 

I got mine from www.OBD-2.com With my setup Jharger, I just plug it in, go online and it does everything itself. Maybe I'll have to shoot an email over to the guy I got it from.

 

Well I put in a new o2 sensor and check engine light hasnt come back on. The guys said that the sensor's are all original. Not bad for 10 yrs and 180,000 km's.

 

So what's that, about 144K miles? When O2's first came on the seen in the mid 80's, manufacturers put a timer on th car, some very simple with a light on the dash, that would go off at 80,000 miles. This was to remind people to replace the O2's.

I think a paranoid mechanic would replace them at 30K miles, proactive 40K, conscious one at 80K and everyone else when the run into problems.

I think that for such a critical EFI control sensor, why not make sure it's always in top condition?

 

no CEL so I'm glad that issue is taken care of. Just need to wait till spring to get the coolant system working 100%

 

Try autoenginuity.com. They make a scan tool for use on a laptop PC or a PDA. Kind of pricey, but it gives you a lot more info than a few dgit display and you can actually monitor O2 sensor waveforms. Google OBDII and you'll come up with sites for some other tools. Good luck.

 

Do we really need to graph O2 output? Maybe R & D activities at an engine building plant. Technology is great, don't get me wrong. But proper application. So far, mechanics have been OK with just being able to tell yes or no that an O2 is switching. If no, fix the lean or rich condition or replace sensor if all else fails.

Kind of like the $1000 cam corder I bought. I've used only about 1/10th the features it has.

 

It all depends on how bored you are. If I was in Sunny Arizona, I'd play golf. But here in 25 degree snowy Ohio, we watch O2 sensor waveforms. Either that, or go in the house and talk to the OL. I prefer the O2 to the OL.

 

Too funny. Yeah to be low 80's this weekend here - still cold.

 

low 80's??? jesus, it's -20 CELCIUS here now

 

No - didn't have to pray for it. Golf anyone?
