Diagnosis of the P0141 Code & Oxygen Sensor
Got the P0141 code which is: the controller tracks how long it takes for the oxygen sensor to begin operation. If too much time elapsed before the oxygen sensor began operating properly, it will set P0141. There are 2 possibilities:
-
the heating element on the sensor is not working.
-
the heating circuit is open, many possible places that the wires are disconnected.
I measured the resistance of the heating element, which is about 6 ohm. Since after reset the engine light does not come on until a few days later, I decide just to replace the oxygen sensor.
P0141 is for the “secondary oxygen sensor” when you order from Honda. Or the “downstream oxygen sensor” when you order from third party store.
I will order one from Honda instead of using the Bosch’s Universal Oxygen Sensor.
