Hi..there..

Normally the oil warning wouldnt cause the fan to kick in that quick under cold engine - so long as the oil has been topped up and that warning has gone out..the only sensor that would likely cause this is the coolant temp sender/sensor thats part of the thermostat housing..some are intigrated in to the whole housing and some can have the sensor replaced on it own without thermostat housing renewal..so best place to start would be to have the coolant temp sensor changed...and see if that solves it..it quite a common problem so it would be well trying that..added to that who ever you do get to repair this they can diagnostically test for fault codes which in turn will confirm if indeed the sensor is at fault.....I do hope this helps
