What does p0161 mean on a ho2s heater?
What does p0161 mean on a ho2s heater?
P0161 is a diagnostic trouble code (DTC) for “HO2S Heater Circuit Malfunction (Bank 2 Sensor 2)”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
Why does my Chevy Silverado have a p0161 code?
P0161 is a very common OBDII code that occurs in the Chevy Silverado. It is typically caused by a failure in one of the elements that heat the oxygen sensors, specifically bank 2 sensor 2. Replacing the Oxygen sensor will fix the problem a majority of the time. Some of the other causes of P0161 are listed below.

What causes p0141 code on oxygen sensor heater?
Faulty oxygen sensor heater (most common) Circuit problems (e.g., damaged wiring, loose connections – fairly common) Issues with the PCM (e.g., software in need of an update – very rare) A circuit problem is one of the possible causes of the P0141 code.
What is the p0161 code for a V6 engine?
The P0161 code only applies to cars with V6 or V8 engines. 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) .

What does p0135, p0141, and p0161 mean?
Won’t pass state mandated emission testing. As mentioned at the beginning of the article, P0135, P0141, P0155, and P0161 DTCs share one specific and common thread: a Heater Circuit Malfunction. What does this mean? Before I jump into an explanation of what the codes mean I’ll share with you some basic working theory of how the O2 sensor works.
