P0167 - Heated Oxygen Sensor (HO2S) 

Heater Circuit Bank 2 Sensor 3

P0167 code definition 

O2 Sensor Heater Circuit Malfunction (Bank 2, Sensor 3) 

What P0167 code implies 

Numerous oxygen sensors are warmed now to carry them to working temperature all the more rapidly. On the off chance that any of the wiring in the radiator circuit for this oxygen sensor is harmed this difficulty code might show up. 

What are the reasons for the P0167 code? 

Harmed wiring in the radiator circuit 

Flawed oxygen sensor 

What are the side effects of the P0167 code? 

At the point when the motor is initially begun, the motor's fuel framework is running in what is classified "open circle". During "open circle," more fuel is utilized to keep the motor running (a rich condition) because of the way that the air/fuel proportions are running on a pre-decided particular customized into the powertrain control module by the producer. 

At the point when the oxygen sensors have warmed up to working temperature, they start to create a sign voltage that is shipped off the powertrain control module. At the point when this occurs, the motor goes into "shut circle." This is the place where the powertrain control module will change the air/fuel proportion dependent on the readings given by the oxygen sensors. In the event that the radiator circuit for the oxygen sensor is harmed, the sensor may never arrive at working temperature causing diminished mileage and terrible emanations. 

How does a technician analyze the P0167 code? 

A technician would almost certainly begin the analysis of the P0167 code by investigating the third oxygen sensor in the second bank of the exhaust to check for any consumed or harmed wiring coming from the sensor. 

This is the most well-known reason for this code. In the event that the wiring for the circuit looks fine, the issue probably lies in the actual sensor. 

Now, the specialist would then test the oxygen sensor for appropriate capacity utilizing the maker's particular strategy. In the event that the sensor ends up being utilitarian, the issue lies in the powertrain control module. 

Normal errors when diagnosing the P0167 code 

Very much like some other difficulty code that utilizes the words O2 sensor, the most widely recognized error that could be made in the present situation is supplant the oxygen sensor as the initial step. 

A few group feel that, for no obvious reason "oxygen sensor" is named in the difficulty code, then, at that point this implies that the part will consequently should be supplanted. This frequently prompts a misdiagnosis and squandered cash. 

How genuine is the P0167 code? 

The P0167 code can be lived with for a brief time frame. Taking into account that this code is identified with the third oxygen sensor in the second bank of the exhaust, the powertrain control module should in any case be getting a sign from the five other oxygen sensors. 

With the signs staying, the powertrain control module ought to have the option to keep a right air/fuel proportion for a while. It would in any case be shrewd to have this issue analyzed and fixed quickly. 

What fixes can fix the P0167 code? 

Supplanting the oxygen sensor
