What Signals Does OBD2 send on my 2001 V70 T5

[Integrexman]

I am using a Kiwi Bluetooth OBD2 with a APP on my Android tablet. I am not sure what signals I should be able to monitor on my V70 T5.

So far the software says it is getting the following from the OBD2 port:

O2 Volts Bank 1 sensor 2(V)
Intake Air Temp(°C)
Engine Coolant Temp(°C)
Engine Load(%)
Mass Air Flow Rate(g/s)
Fuel trim bank 1 sensor 2(%)
Throttle Position
RPM
Speed

I thought I would see more signals like the boost pressure from the turbo, and I know one of the O2 sensors is bad so that is why the software only see's one O2. Is there more than one Fuel Trim on this engine? My friends Hummer H3 V8 has 4 fuel trims and 4 O2 sensors. Will it send the MPG info that is displayed on the cars dash? Thanks for the help.

I'm not sure all of what it sends. I was able to get the same data that you listed. I'm using an ELM327 and the Torque APP on my Android (Froyo). It is really cool.

Make sure you set the size of your engine in the settings so the MPG will read correctly. I'm not sure how accurate the MPG reading is since I don't have that read out on my dash. Maybe you could report back to see how accurate the APP's MPG display is versus the dash computer.

The Torque APP is cool and I like it a lot. It has loads of information and the HUD mode is really cool at night.

OBDII does not typically cover boost pressure (requested or actual), thats usually manufacurer-specific. The closest you will get is the MAF flow in g/s. The 5cyls only have one fuel "bank" therefore only two O2 sensors. Each bank has two trims short and long, so you should be seeing two trims from the single bank. MPG is a guesstimate based on injection on time and airflow over the MAF sensor, its not always accurate as its assuming your fuel system pressure to be perfect.
