P0141 Code: Oxygen Sensor Heater Circuit Malfunction (Bank 1, Sensor 2)P0141 is part of a family of codes listed as follows:
P0141 – Sensor Heater Circuit Bank 1 Sensor 2
P0161 – Sensor Heater Circuit Bank 2 Sensor 2
P0135 – O2 Sensor Heater Circuit Bank 1 Sensor 1
P0155 – O2 Heater Circuit Bank 2, Sensor 1
Make sure you know bank 1 from
P0042 Code: HO2S Heater Control Circuit Bank 1 Sensor 3When there are only 3 O2 sensors it’s typically because there’s only one catalyst being monitored, and “Bank 1” is the default designation when there’s only one sensor in a category.

P0135 Code: Heated O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 1)Due to this, the O2 sensor features an integrated heater circuit to bring it up to operating temperature after a cold start. When this circuit stops functioning properly, it can trigger a P0135.
The oxygen sensor monitors your vehicle’s air-to-fuel ratio.
What Does the P0135 Code Mean?
