Decoding the P0141 Code Empowering Drivers with Knowledge

The code is P0141: heater malfunction on the downstream O2 sensor. No big deal. I replaced both the upstream and downstream O2 sensors with BOSCH purchased ... P0141 is the heater circuit/function for that O2 sensor. Anytime you get a code the only thing you know is that circuit/function has a problem. Means the heater circuit for the downstream O2 sensor has a problem. It's located aft of the cat converter under the middle of the van. More ... The trouble code P0141 warns about an issue in the heating circuit of the catalytic converter's downstream oxygen sensor. What it means is that there is extensive resistance in the heating circuit of the 02 sensor. How long ago did you install this sensor? Have you ... Looks like your downstream HO2 sensor has bit the dust. Check fuse but first HO2 would have set codes also. Check for broken wires first, but my ... P0171 means the pre O2 sensor is reading a lean condition.....low fuel pressure, a vac leak, an exhaust leak, etc. P0141 means the post O2 sensor is taking too ... This trouble code typically points to a damaged sensor heater or related wiring. Similar trouble codes include P0135 and P0420. P0141 is showing an issue with the heater circuit. This can be sometimes difficult to diagnose because it could be the sensor or heater circuit ... Yes the code refers to the second sensor (the one behind the cat). Does the software you are useing allow you so see data from the sensor? By ...
