Test 3 oxygen heater element s ohming.
P0161 02 sensor heater circuit bank 2 sensor 2.
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.
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.
Vehicle emissions could be increased due to this problem.
O2 sensor heater circuit malfunction bank 1 sensor 2 what the p0141 code means.
Bank 2 refers to the side of the engine opposite the 1 cylinder.
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.
The p0161 trouble code identifies that there is a problem with the heater control circuit in the bank 2 sensor 2 oxygen sensor.
P0161 oxygen o2 sensor circuit low b2s2 technical description.
Code p0161 stands for ho2s heater performance bank 2 sensor 2.
It sends critical feedback data to the power train control module or pcm that tracks the operational efficiency of the catalytic converter.
Replacing the oxygen sensor will fix the problem a majority of the time.
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.
This diagnostic trouble code dtc is a generic powertrain code which means that it applies to obd ii equipped vehicles.
Note that you may need to check the entire black wire with white stripe between the pcm connector and the o2 sensor connector.
Instead a faulty downstream heated oxygen sensor will be set as p0141 or oxygen sensor heater circuit malfunction bank 1 sensor 2.
The p0161 code only applies to cars with v6 or v8 engines.
This test checks whether the o2 sensor for bank 1 sensor 2 if fired or not.
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.
You will test the oxygen sensor and not the sensor harness connector.
Although generic the specific repair steps may vary depending on make model.
What the p0161 code means.
This indicates the pcm has detected a problem with heater circuit of the downstream oxygen sensor.
