I have a 2007 Chevrolet Impala V6 Flex-Fuel. Recently, the Check Engine Light came on. I decided to drive the car with the light on for a few days as my engine code reader was packed away. About four days after the light came on, I topped off the engine with a quart of oil (this car loses about a quart a month). The CEL went off the next morning and I never had the opportunity to read any code off.
Is there any plausible reason that the CEL would have been triggered by a low oil condition or would have been resolved by adding more oil? Is this likely nothing more than a coincidence? The low oil warning on the car did not activate at any time during this occurrence.
Note that I don't need help with the light - it is off. I'm asking how likely it was that topping off the oil was what fixed it. To my recollection, this had not happened before.
