Code P2197 Common Diagnosis Mistakes Prematurely replacing the oxygen O2 sensor before attempting to visually inspect the wiring around the other components of the intake system for fraying or disconnection.
The zirconia generates voltage from approximately 1V in richer conditions to 0V in leaner conditions. P2195 means the sensor between the engine and the catalytic converter not the one behind it. It has 115,000 miles on it. Most other components outside of the intake system and the O2 sensor itself will affect both banks of the motor. What repairs can fix the P2195 code?
