welcome again, and glad to help you,
yes, the duty cycle must be set, with any changes to the air leaks, and for age the iSC will leak a bit and we correct that with the bleed, (Cw turned to attain 50%)
CO2? really they do CO2... the least harmful smog gas of them all. ? wow.!
not HC? (unburnd petrol)
not NOX (nasty of the big nasty, acid rain, and burned lungs, horrid stuff) was almost killed on boat a large ship by this gas... (blacked out)
not CO (deadly of all, carbon monoxide, like breathing BBQ fuses , death...)
that is really crazy , as and engine that burns every drop of fuel, leaving no OXYGEN left , has MAX CO2, (that is why smaller engines are the cure to high CO2 and cure to GLOBAL WORMING (sic, pun intended)
0.7 grams per mile or KM, my guess. not percent.
see this chart, See CO2, this is a fact..... of life.... CO2 is the peak on all stock cars.
best test is 5 gas, shows them all, and we can judge what's UP.

The 02 may be bad. if old it probaby is. bad.
or have exhaust leak.
post your full smog station report, please. I can read them well.
also , you can replace the CAT, and this can hide a dirty engine (smog)
the stock cat is 3way cat. and cuts 3 forms of smog.
what folder is your new photos,, would love to see them as I have the others...?
the chart above is before the CAT, after is way less. but not CO2.
normal CO2 emission on 1.6L gas engine is tad below 200gram/mile.
note when accelerating C02 drops , then the engine wastes fuel.
then CO rises, the most deadly of all gases (related to burning petrol gas)
love to see the smog fail paper.
all things equal the best MPG gives you less CO2.
more fuel burned the more CO2
but if you burn at at STOICH, the C02 is less, like in closed loop at 45mph.... bang. less co2. and 28mpg. in this car.
now the cat,
when the cat receives excess HC, or CO, it converts that to what, CO2, so my chart is wrong at the end of the CAT, if the engine runs rich.
when HC is too high so is 02, and is used to make Co2. at he CAT.
are you sure they are testing for CO2?
to pass the CO2 test, one gets it to max, with 02 lowest.
most G16s running poorly (smog wise) are rich. and some even make extra power doing so, that fools many a person.
to pass test at 2500rpm (here is 25mph and 15mph)
get the ECU into closed loop. at 2500 steady throttle (means the 02 sensors is holding STOICH Air to fuel ratio )
and it will pass.. his tests.
if not, the CAT is bad. (or o2 bad , it can seem to work but is poisoned and biased. and is good cause to put in a new one well before the smog man looks.)

this is a passing sidekick
HC is tad high but that is weak CAT but passed by a hair.
note the 14% CO2, totally normal and totally high.!!!

note the real low CO
and low 02.
a good burn.
wish i had pre CAT data but dont. my guess HC is high because cat is Cold or weak.
don't do the test until you get that CAT good and hot.

Quote:then, I took the vitara to another workshop to see how was about CO2,
and the idle was 0,5 it is correct to pass the Technical Inspection although the idle is unbalanced for the moment, but when accelerate to 2500 r.p.m the machine gave 0,7, but the correct to pass Inspection is 0,3, so I think and the mech too, the oxygen sensor is faiing, then we callad to the shop 4X4 to bring a new one, they said it will come tomorrow.."

Quote:I told to the mech two months ago to get a new Oxygen sensor, but he said the OBD mark not problem, but today he told me maybe it is failing .. Crazy story..
