OBD2, oil level?
OBD2, oil level? I have a 2002 engine, red-blue PCM. I know the computer originally sent my oil level warning through the BCM serial to the dash. Does anyone know if this is also in the OBD2 data? I’m doing a dash conversion that uses OBD2 data and I’m wondering if that sensor might be able to be seen by it.
Does anyone have a list of the available parameters in our OBD2 stream (rpm, coolant temp, etc.)?

it isn't a true level sensor, in the oil pan, it is low level switch. It turns on when the level is too low

I hooked mine up to a light on dash but it comes on every time i corner, accelerate, or brake hard. On stock vehicles it never comes on unless about 2 qts. low. So how does it get wired on a stock car or truck to keep it from giving false alarms? Does it route through a computer that only turns low oil light on when there is a constant signal from low oil sensor for a predetermined amount of time to prevent false alarms?

Yes thanks for reminding me I had to wire it to a relay with ignition power to reverse the contacts or the light will stay on all the time and go off when oil level low, I ended up disconnecting the light all together because it was constantly flickering on when cornering and driving around. I did install a new sensor thinking the used one was possibly bad but same issue. It would probably work if you had a timed delay of a minute or so to eliminate false alarms, I figured for the extra trouble I can check the dipstick every so often, just would be nice to have it functional. The factory must have it on a timed delay through a computer possibly the bcm? to figure out when its actually low and not just sloshing around.
