Is there a function in Torque to indicate whether or not the engine light is currently on or off?
This is going to sound crazy, but my MIL light no longer illuminates(likely a burnt LED or something). Whenever I have to pass inspection, I need to borrow an OBD2 computer just to find out if the light is on or not!
Here in NY, I think you need 7 out of 8 readiness tests to pass inspection, and your engine light has to be off. The OBD2 device I used to borrow would tell me the status of readiness tests as well as whether or not the MIL was on or off. If 7 tests passed and the MIL was still reported as off, I was good to go. But if it indicated that it was ON, I had a real problem to fix or try again.
So, I know most folks would not need such a feature since they could just SEE if their light comes on. But I need something like Torque to tell me- is there a way to do this?

An OBD2 handheld reader I borrowed from a mechanic last year used to say on the display "MIL Indicator" followed by ON or OFF before the readiness codes.
So, that means the OBD2 protocol must sent that data over the port, right? If Torque can't display it, is there a terminal command or something I can enter directly using an OBD terminal app?

After much frustration, I ended up finding 2 other apps in the Android market that did what I needed.
Both ScanMaster Lite (by WGSoft.de) and Car Gauge(by OBD ScanTech) have emissions readiness screens complete with MIL on/off status. The former seemed to work consistently and quickly, while the latter was buggier and dropped the connection a few times.
Still, would love to have this kind of functionality in Torque.

Yes I would ALSO like this feature... Need to be able to know if a MIL has occurred then query the DTC codes and LOG them.
Want to be able to check for particular DTC and issue DTC reset to clear..

Have you tried adding the pids
for MIL and DTC counts under
settings > manage extra PIDs...
then adding your own displays.
The mode/pid info should be
readily available.
http://en.m.wikipedia.org/wiki/OBD-II_PIDs#section_5
Edit:
DTC Count (bits A6-A0)
mode/pid: 0101
equation: A&7F
use digital display type
MIL Status (bit A7)
mode/pid: 0101
equation: {A:7}
use on/off display type

Just tried and always reads OFF. What should go in MAX/MIN ? (Just need CEL status, not count).
ScanMaster also always reads off.
This is with an '07 Chrysler Crossfire.

Zero (0) and One (1) should work
for bit examinations. ON/OFF display
type should work.
Double check your equation... if it
matches above then test with different
header values for a response.
What protocol is your vehicle using? ISO?
It would only read zero until there is an
DTC to turn it on.
If the DTC Count pid is zero then the MIL
shouldn't be ON.

Triple checked tried 0/1 and 0/65536
Uses ISO but not certain if Chrysler or Mercedes PIDs. Is a '07 Chrysler Crossfire but Torque scan does not find many data points (no misfire info) for something that late.
ScanMaster also always reads off.
Protocol is ISO 14230-4 KWP fast so pre-Canbus.
What header values would you suggest & what is header format please (did not like 7E0).

Maybe Auto, blank or 686AF1?
Have you tested the pid while in
the pid editor? If so, what was the
raw hex response?
Without a DTC present it would be
working.
Edit:
4101... is a successful response.
Key-On is not a DTC, just a momentary
lighting of the MIL to verify indicator is
working properly. (IMHO).

686AF1 produced "no data"
Blank and Auto both gave the same result whether CEL on of off. 41010007EDED
I appreciate someone knowlegable helping.

Just a thought but will this value change only if an error code is set and not just with a key-on ?
