I have a 2016 nissian Altima. 110k miles. It is an automatic. I keep getting 02 bank1 senor 1. Which was replaced. The check engine light keep coming on and the obd reader said it's the 02 sensor. Also a lean code. I don't have the exact codes. Could this be a computer issue?
You have to find out what is causing the sensor to show a lean code, not that something is wrong with the sensor. Start with the basics - air filter, MAF sensor cleaning, partially clogged injector or dirty fuel filter, etc.
Those models have a bulletin to replace the air fuel sensor and inspect the pcv valve and a modification to the front grill shudder for a/f sensor codes which could very well also cause a lean code
