Oxygen Sensor Heater Duty Cycle at Jamie Spencer blog

Oxygen Sensor Heater Duty Cycle. most manufacturers list that spec in their service information, so you can check heater current yourself with a current probe. dtc p0141 stands for “oxygen sensor heater circuit malfunction (bank 1, sensor 2).” it indicates that there’s a problem with the heater circuit of engine bank 1’s downstream o2 sensor. but o2 sensors fail over time, triggering check engine lights and lean/rich running conditions. it is used to determine the concentration of oxygen in the exhaust gas. This information is used by the pcm to control the engine air/fuel. On afr sensors, you can also see heater current duty cycle with an amp probe and a dvom or with a scope, but you probably won’t find a specification. Your car’s pcm tests the oxygen sensors’ heater circuits for integrity. the car that is in my classroom is a 2007 nissan sentra with a wideband o2 heater circuit fault (p1148,. rough idle at startup and check engine light isn’t a guaranteed o2 sensor heater circuit malfunction, but in our experience it’s the most likely the explanation.
