P0161 02 Sensor Heater Circuit Bank 2 Sensor 2

O2 sensor heater circuit malfunction bank 2 sensor 2 downstream code p0161 meaning heated oxygen sensors contain heating elements to help them get to operating temperature quickly in order to minimize the amount of time spent before they can provide feedback to the powertrain control module.

P0161 02 sensor heater circuit bank 2 sensor 2.

What the p0161 code means. Obd ii code p0161 is defined as a oxygen sensor heater circuit malfunction bank 2 sensor 2 the rear oxygen sensor is located in the exhaust system behind the catalytic converter s. Note that you may need to check the entire black wire with white stripe between the pcm connector and the o2 sensor connector. It sends critical feedback data to the power train control module or pcm that tracks the operational efficiency of the catalytic converter.

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. This test checks whether the o2 sensor for bank 1 sensor 2 if fired or not. Test 3 oxygen heater element s ohming.

Replacing the oxygen sensor will fix the problem a majority of the time. P0161 oxygen o2 sensor circuit low b2s2 technical description. Code p0161 stands for ho2s heater performance bank 2 sensor 2. The p0161 trouble code identifies that there is a problem with the heater control circuit in the bank 2 sensor 2 oxygen sensor.

The p0161 code only applies to cars with v6 or v8 engines. P0161 is a very common obdii code that occurs in the chevy corvette it is typically caused by a failure in one of the elements that heat the oxygen sensors specifically bank 2 sensor 2. Vehicle emissions could be increased due to this problem. You will test the oxygen sensor and not the sensor harness connector.

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. O2 sensor heater circuit malfunction bank 1 sensor 2 what the p0141 code means. P0161 description the powertrain control module supplies a bias voltage approximately 450 mv on the heated oxygen sensor ho2s signal high and low circuits when you turn the ignition to the on position battery voltage is supplied to the ho2s heater.

Oxygen o2 sensor circuit low voltage bank 2 sensor 2 what does that mean. P0141 is the obd ii generic code indicating the engine control module ecm has tested the o2 sensor heater circuit and detects a problem with the bank 1 sensor 2 oxygen sensor heater circuit.
