Will the OBD computer reset itself if I fixed the thermostat on a 2001 altima

Question

Engine warning light was on in my 2001 altima.  Connected the OBD scanner and read the code to be a thermostat problem.  Looked at the sensor and discovered it was disconnected.  Reconnected it.  Gage works.  But warning light still on.  Will it eventually reset itself.

Answer 1

Yes it will, one of the job for the ECM is to look for open circuit grounded circuit, and rationality, If the code was for a disconnected connection the you would set a circuit high which is a open circuit, When the ECM see the correction and there is no other fault , the CK ENG LT should turn off.
