Mil light comes on with no affect to vehicle performance. Fault code P1115 unknown code present. Autodata description is P1115 engine coolant temperature sensor 2 ecm controlled cooling system-circuit malfunction. Used picoscope to measure temp sensor output-perfect reading with no glitches which mirrors what is seen on live data.fault code returns as soon as vehicle is started. Had no time to go any further.just wondering wether the autodata description is correct and wether there is a 2nd coolant sensor or is it possibly refering to the electric thermostat.
thanks in advance alwyn
