A month ago I had again the P141 code for my check engine light.
In the past I had the same code but it went out by itself but now this code is lasting for a month. The engine light came on in a cold day when I was just leaving my garage to go to work and is on up to this date.
According to Autozone printed sheet of the symptoms like hight fuel consumption, it is not my case because the car is giving me the same mileage per gallon same than it was before. The car is running without any trouble comparing before the check engine light.
Since the car is running normal, are there some suggestion in what to do or just ignore this code?
Thanks

You could check the OS sensor at Bank 1 sensor 2. IIRC is aft the turbo tucked up next to the firewall. Not easy to get to.
