Why is my O2 sensor code po161?
I replace my O2 sen cause I was having PO161 CODE after replacing my O2 sensor the CEL turned-off. 20 miles later PO141 and PO161 came back on. Any idea what is going? I order a replacement O2 SEN part thinking it’s defective.
Why does my PCM set the code p0161?
There are a couple of reasons why the PCM could set the code P0161: 1 Faulty oxygen sensor 2 An issue with the oxygen sensor heater circuit (i.e., an open, a short, or high resistance) 3 An issue with the PCM
What does Bank 2 O2 oxygen sensor do?
It warns about an issue with the Bank 2, Sensor 2 oxygen (O2) sensor’s heater circuit. Modern oxygen sensors come with heating elements so that they heat up to the ideal operating temperature quickly. They provide feedback to the car’s computer or the powertrain control module (PCM).
What’s the code for an oxygen sensor malfunction?
Instead, a faulty downstream heated oxygen sensor will be set as P0141 or Oxygen Sensor Heater Circuit Malfunction (Bank 1, Sensor 2). Vehicles that are prone to code P0161 include various models of Chevrolet (especially Chevy Silverado), Ford, Jeep, Toyota, and Dodge.
Can a faulty oxygen sensor trigger a p0141 code?
If your vehicle only has four cylinders, it will only have one bank and, typically, one downstream sensor, so it can’t trigger this code. Instead, a faulty downstream heated oxygen sensor will be set as P0141 or Oxygen Sensor Heater Circuit Malfunction (Bank 1, Sensor 2).
