What does code P1195 mean?

P1195 · ChryslerO2 Sensor 1/1 (Bank 1 Sensor 1) Slow During Catalyst Monitor

P1195 on Chrysler vehicles means the powertrain control module (PCM) saw the upstream oxygen sensor on bank 1, sensor 1 respond too slowly during the catalyst monitor test. The PCM commands a rich-to-lean fuel swing and expects the sensor voltage to cross its threshold within a set time, but the signal lags, so the monitor fails and the code is stored.
