What does p0161 mean on ho2s Bank 2?
Code P0161 stands for HO2S heater Performance Bank 2 Sensor 2. This indicates the PCM has detected a problem with heater circuit of the downstream oxygen sensor. Bank 2 refers to the side of the engine opposite the #1 cylinder. If you’ve got a four-cylinder, there will only be one bank, and you would not get this code.
What causes the p0161 OBD-II trouble code?
This code means that the bank 2 sensor 2 oxygen sensor is not warming up properly due a problem in the oxygen sensor heater circuit. Vehicle emissions could be increased due to this problem. What causes the P0161 code?
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).
Why is my bank 2 oxygen sensor not warming up?
This code means that the bank 2 sensor 2 oxygen sensor is not warming up properly due a problem in the oxygen sensor heater circuit. Vehicle emissions could be increased due to this problem. What causes the P0161 code? The P0161 trouble code is caused by an incorrect amount of resistance in the heater circuit.
