DTC P1195: 1/1 O2 Sensor Slow During Catalyst Monitor: Description
WARNING: This page is about a different car, the 2000 Dodge Intrepid, 2000 Chrysler LHS, 2000 Chrysler Intrepid, 2000 Chrysler Concorde, and 2000 Chrysler 300M. However, it is still accessible from the selected car via links, so may be relevant.
1/1 Heated Oxygen Sensor (HO2S) catalyst monitor is monitored with engine running, coolant temperature more than 170°F (76.7°C), open throttle, vehicle speed steadily increased to more than 18 MPH but less than 55 MPH, and light engine load exists for at least 5 minutes. DTC will set in Powertrain Control Module (PCM) memory when PCM senses 1/1 HO2S is switching from less than .39 volt to more than .6 volt fewer times than required. Possible causes for DTC to set are: oil or coolant consumption, defective 1/1 HO2S, defective connector or defective wiring.
