If you can start the car then connect to the RSTuner software with your laptop or whatever and go to "live data" you should be able to see the value?

The rear on mine is about 400-439mV

My front fluctuates like f**k between 48.8 and 751.52mV

God knows if that helps!

i have to look at that no idea what i reads tho

Orange faults are just Saved ones so you can get rid of them red ones are present faults.

Just try clearing them and going for a drive then reconnect see if there still there mate

charging the laptop up atm so may try it tonight or will tomorrow see if i can re-create the fault

TB related problems would be my educated guess, try giving it a clean first

you not the 1st person to say that

The red one is not a fault though....

 

[edgeydt50]

it even says not a fault?

 

[richy22]

it even says not a fault?

Hence why I posted that above!

 

[mattjk]

it didnt say it wasnt a fault in the original screen dump though?

 

[richy22]

No correct but thats the not whole screen dump??

 

[mattjk]

well how the f**k was i supposed to know?

 

[richy22]

well how the f**k was i supposed to know?

Chiiillll Winston! (PMS !! )

It could well be a fault I was just showing what mine said, and looking at the first screenshot I can't see the not a fault in brackets after that as well?? (my double ?? means confused!)

 

[fil_b]

will look at the tb when i get a chance see if that makes a diff

has TB on 172 been a issue for many peeps??

 

[mattjk]

I'm perfectly chilled lol I just didnt have a clue what you were on about!

Anyway! So why did it come up on yours and say not a fault, out of interest did you ever find out?

You ever cleaned the TB before, its easy and free, a good starting point!

Apparently its normal so I was told! Thought they all do that? I could well be wrong!

That throtle one is not a fault, Henk says it is the throthle reaching it max values. that si normal and present in mine as well

The brake one is also very common, I had a 182 and now a 172 and both have that fault, it is the brake contactor that gives that error from time to time, actually, very often.

To me your problem is the actual 02 sensor, and it says is the front one, the one before the CAT (or where there used to be one LOL), it may be on its way out. I had a decat on my 172 and the O2 sensors never gave any errors so I am not to sure is the decat the root cause. If the 02 sensors fail the car can not adjust mixture well making the car run like crap.

had my TB off

Had a bit of oil in there

this look normal?

did top my oil up a bit on saturday as it was half way between min n max

didnt put much in

 

[Jamesstone]

Looks fairly normal mate, just looks like oil from the cranckcase breather

 

[fil_b]

that ok

well clean it so see what diff that makes

other thing is 02 sensor

right so, You have 3 faults
1)TB code that people are saying normal?
2) A brake code, but as long as your ABS is working ok nothing to worry about - people are saying that's common too?
3) You have a lambda fault and poor engine running at partial throttle. This points very very strongly to a faulty upstream lambda.

When lambda goes, sometimes cars will 'lag' on partial throttle and then suddenly pickup - this is the fuelling correcting itself after it's decided the lambda signal is sh1te afaik.

Personally, i'd get the lambda changed. You'll probably see a MPG increase. how is your MPG? Should be around 34-36 tbh if your driving properly.
