P2196 code

This code typically means the exhaust stream has too much fuel in it - as measured by the oxygen sensor before the catalytic converter. If the fuel injectors are not leaky, the next step would be to determine if there is a spark or air intake issue. Coils that are not firing or spark plugs not igniting can cause a fuel rich issue. Hands on testing by a professional is suggested. https://repairpal.com/auto-repair-near-me
