DTC P2195: General Description
When the air/fuel ratio (A/F) sensor (sensor 1) is properly connected to the engine wire harness, but it is not installed in the exhaust pipe, the feedback is not done properly even if the A/F sensor (sensor 1) is active after starting the engine. Thus, the exhaust emissions increase. When the A/F sensor (sensor 1) output stays out of the normal range after the A/F sensor (sensor 1) becomes active, the powertrain control module (PCM) detects that the A/F sensor (sensor 1) is not properly installed and stores a DTC.
