How many 02 sensors, What is a bank, what data is available? 2000 3 litre

micky

Hi,

I have a 2000 Solara with the 3.0 litre V-6 engine.

I also have a Scan-Gauge II.

Besides the built-in guages, the SGII can have other gauges added,
which may or may not find data in the car's computer to display.
That is, not every gauge applies to every car, but I think some of the
ones below apply to this Toyota.

"Most Asian, European, and Chrysler manufactured vehicles used the ISO
protocol from 1996 to 2002. From 2003 to 2007 their vehicles will
either support ISO or CAN."

In my 2000, ISO mode was used, and among the possibly available ISO
measureable things ("gauges") are 02 Sensor Data and Fuel Trim Data,
Air/Fuel ratio and Catalyste Temperature each of which uses the terms
Bank and Sensor, but I don't know what this engine has .

For 02 Sensor Data, there are separate gauges for Bank 1, Sensor 1, 2,
3, and 4, and Bank 2, Sensor 1, 2, 3, and 4. That's 8 possible
entries, but iiuc my engine has only 2 oxygen sensors, one for the
odd-numbered cylinders and one for the even. . Is that right?

What does it mean by Bank? The odd or even numbered cylinders? That
seems reasonable except for the next category:

For Fuel Trim Data. there are separate gauges for Short Term Fuel Trim
Bank 1, 2, 3, 4, 5, 6, 7, and 8 So it couldn't be the odd versus
efven cylinders.

For Air to Fuel Ratio it has
A/F Ratio Bank 1 - Sensor 1, 2, 3, 4
A/F Ratio Bank 2 - Sensor 1, 2, 3, 4
Alt A/F Ratio Bank 1 - Sensor 1, 2, 3, 4
Alt A/F Ratio Bank 2 - Sensor 1, 2, 3, 4 and
Alt A/F Ratio Bank General
-- Does this engine have Air/Fuel ratio sensors?

For Catalyst Temperature, it has
Catalyst Temperature Bank 1, Sensor 1 and 2 and
Bank 2, Sensor 1 and 2.
--Does this engine have Catalyst Temperature sensors?

Thanks for any help.

Scan Gauge II costs about $150. It reads and removes trouble codes,
it displays a lot of engine info, it keeps track of yesterday's and
today's info separately, and has sort of performance measurement
feature.

Bank 1 is the bank that serves Cylinder 1, Bank 2 is the other cylinder, if
there is one. All engines have Bank 1, they do not all have Bank 2. An
Inline 6 can have an exhaust configuration that only has Bank 1, or it can
have a split manifold which will give it a Bank 2 also. Your engine is a V,
so it has Banks 1 & 2.

Sensor 1, Sensor 2 and so on, define the position ahead of or behind the
CAT. Sensor 1 is before the CAT, Sensor 2 is after. Some systems have more
than one CAT, so they have more than 2 sensors. For example, Sensor 3 would
be after the second CAT, if there was one.

So, Bank 1, Sensor 3 would be the sensor on the exhaust side that serves
Cylinder 1, and after the second CAT. I have never seen more than 2 banks of
cylinders. I have never even heard of more than two banks of cylinders.
Having said that, I'm gonna guess that there could be certain high
performance engines that could have an O2 Sensor on each tube of the exhaust
manifold. I can't imagine what the benefit of such a system would be other
than to have tighter monitoring of each individual cylinder, and I can't
imagine why there would be a need for tighter monitoring. If one had a V12,
I could see a Bank 1, Bank 2, Bank 3, and Bank 4 because each bank of six
cylinders might be served by two manifolds that handle the exhaust from
three cylinders.

O2 Sensors measure air/fuel ratios, that's all they measure. Sensor 1 looks
at the exhaust that just came out of the cylinders, and tells the computer
that the mixture is correct, or not. The computer uses the information to
retain or change the fuel injector timing tables. Sensor 2 looks at the
exhaust that comes out of the CAT and compares the result to that of Sensor
1 to determine the functionality of the CAT -- if Sensor 2 sees the same
amount of fuel after the CAT as before, then the CAT is malfunctioning.

CATs do not have temp sensors, well they could, but I have not seen one.
CATs operate at high temps, and if the temp is low then the CAT efficiency
is low, if the temp is high -- beyond what is normal -- then this indicates
a malfunction. The O2 Sensors also need high temps to operate efficiently,
so they have a heater built in that comes on on Cold Engine Start to warm
the sensor before the exhaust itself has the chance to warm the sensor.

There are codes that exist that all engines will not make. For example,
there is a code P0309, MISFIRE CYLINDER 9, that can only occur in an engine
with more than 8 cylinders.

Just because your scan tool has a manual with code definitions in it does
not mean that your engine will ever produce all of the codes. Do not obsess
over the meaning of the codes until your engine actually throws one.

Thanks for a wonderful answer. I don't know how to say that more
strongly except to say it twice. Thanks for a wonderful answer.

Yes, I understand, and the manual itself makes that clear too. This
is designed for (just about?) every car made since 1996, and not every
car can sense every thing. And I get the impression that earlier
years are likely to have fewer kinds of data than later years.
(Although everything I posted about is ISO data which was use earlier
and iiuc is gone in new cars or fading away.

> Do not obsess

Although the Scan Guage II will read codes and clear them, this part
of the manual and the operat was not about codes. It's about what
they call gauges, data which (if a particular car reports a
particular kind of data) will always be reported, the actual value,
not whether it ia good value or a bad one. (The Scan Gauge II depends
on the car to set the codes, of course.)

I know that any of the values I mentioned (and others I didn't mention
that didn't go into bank or sensor) might not be provided by the car,
but from your explanation, I know that anything with a bank higher
than 2 will certainly not be provided. And I'm prettty sure I only
have one cat, so anything higher than 2 won't be provided.

The device comes with a lot of "gauges" pre-installed**, but for some
reaosn these other "gauges" have to be installed by the owner. Each
one requires my entering 38 characters, spread out over four parts .
Thatt's going to take some time, but you've made clear to me that I
don't even have to try installing a lot of them. So you've saved me a
lot of time.

**Gauges that come pre-installed are
Miles per gallon (or KPG, KPL,KPL or LHK)
MPH (or KPH)
RPM
Water Temp, in F or Centigrade
Average Fuel Economy
Votlage
Intake Air Temperature
Gallons per Hour (or litres)
Ignition Timing
Engine Loading
Horsepower (though it goes from 3 to 50 or 60 even though I have a 192
HP engine . There's a (separate?) ISO gauge for HP that might give
different results after I add it.

Gauges the Scanguage has that my car doesn't seem to have are
Trasmitssion Fluid Temp
MAP and Boost (It can't have boost because it's not supercharged or
turbocharged, but it could previde MAP, but doesn't.

I can't remember if it shows something for the Throttle Position
Sensor. gauge.

It also has a trip computer that will keep trrack of yesterday's
mileage, and if you enter the cost of gasoline, it will keep track of
dollars per hour etc.

It also has a performance monitor, that keeps a running record of
time, speed, distance, and one other measurement of your choice every
two or four tenths of a second, up to 24 seconds, or when you slow to
a stop. You can recall the data until you turn the engine off, or
you can save it. You can save 8 sets of data, and recall and display
each of them. I doin't know where there's a spot both safe and safe
from the police to do acceleration tests, and I'm too old to care
much. On the ohter hand, if the car is ever not working right, I
might be able to debug it by watching a given gauge for 24 seconds of
acceleration or deceleration.

And I plan to take this with me to the next car.

One thing worth noting. In the 2000 Solara, there was no really good
place to mount it. Very few flat surfaces, very few empty spots
where it wouldn't obstruct something. I ended up putting it halfway
down the dash, just under the speedometer, just above the side mirror
contrrol and to the right of that, just near something, with the
cable going in the hole where the steering column is. (the cable
comes out the right side or the rear, either one.)
Plus you have to be able to grip it or to push on it, in order to
change functions etc. The buttons work easily, but it has to be
mounted at least stlightly firmly, or you have to be able to get a
finger behind it to squeeze it. Dimensions are on teh webpage. I
assume their accurate but I haven't checked.

There is a cheaper, slightly smaller model ScanGauge LE or something,
It doesn't have as many features. It might have one more feature, but
I didn't need it and I forget.

I'll tell you more if you want.
