Question

P0141 Chrysler 02 SENSOR BANK 1 - I PUT A NEW SENSOR IN IT LASTED FOR 3 DAYS THEN THE CHECK LIGHT CAME BACK ON.

Answer 1

P0141 -02 sensor heater circuit malfunction Bank 1 Sensor 2

This is for the downstream 02 sensor, For this code to occur there may be a open connection with the heater circuit of the 02 sensor, Even wrong application of the 02 sensor will cause this code to occur.  Here is a Chrysler with a P0141 the 02 sensor was replaced and it coded a P0141 , The same day, what happen is the part application calls for 2 different 02 sensor , one being at a higher price and the other a lower price,  Low price was good deal and it only lasted 8 hours. When a 02 sensor codes a heater circuit failure it may just be a failed 02 sensor or wrong type of 02 being installed. If you have only P0141 , you may also just have a harness issue, if it was a heater control problem with the ECM  you would also have Bank 1 Sensor 1 heater 02 sensor settting a heater code condition.P0141 it just confined to Bank 1 Sensor 2
