Model: 1996 nissan sentra Fault Code: P0171 Posted: 2016-11-11 11:32

My 1996 Nissan Sentra 1.6L vehicle has been experiencing repeated failures of the Bank 1 O2 Sensor 1. I replaced it just two weeks ago, but it failed again yesterday. What could be causing this sensor to keep failing so frequently? Are there any underlying issues in the engine management system or exhaust flow that might be contributing? Any insights or diagnostic tips would be greatly appreciated.
