In a Chevy Malibu, if you see the code p2097, it signals a problem with the post catalyst fuel system. Specifically, it indicates that the fuel mixture reading from bank 1 is showing higher richness than normal. This issue might stem from a faulty o2 sensor. If you suspect the fuel system is functioning properly, consider replacing both oxygen sensors next. The cost for a new oxygen sensor for this car ranges from $15 to $40, depending on whether it's a standard version or an authentic Chevy part.
