Hi all, I have been monitoring sensors on the KJ via OBD useing the Torque app.
I have a strange reading that I dont know what to make of it.
The Engine coolant temp shows what I expected at 92C but there is another reading called ECU(18) Engine Coolant Temperature that shows -32c with ambient air temp of +5c at the moment I took this reading...
any ideas?
