What is the trouble code for O2 sensor?
P0131 OBD-II Trouble Code: O2 Sensor Circuit Low Voltage Bank 1 Sensor 1. Cost of diagnosing the P0131 code. P0131 is a diagnostic trouble code (DTC) for “O2 Sensor Circuit Low Voltage Bank 1 Sensor 1”.
Where is the fault in the oxygen sensor?
P0131 is telling us there is a fault in the oxygen sensor, located in the bank 1 sensor 1 location of the vehicle. This is also called air/fuel sensor, or heated O2 sensor.

P0131 is telling us there is a fault in the oxygen sensor, located in the bank 1 sensor 1 location of the vehicle. This is also called air/fuel sensor, or heated O2 sensor.
How does the ECM work with the oxygen sensor?
From the oxygen content, the ECM can determine if the air/fuel ratio is rich or lean and adjusts the fuel mixture accordingly. A rich mixture consumes nearly all the oxygen, so the voltage signal is high, in the range of 0.6 – 1.0 volts.
Which is the oxygen sensor on a V-type engine?
On V-type engines one sensor will be referred to as Bank I Sensor 1 and the other as Bank 2 Sensor 1. The oxygen sensor after the catalytic converter is used by the ECM primarily to determine catalytic converter efficiency. This sensor is refer-red to as sensor 2.
What does the O2 sensor on a car do?
One of the most important sensors in modern cars is the oxygen sensor. Also known as the O2 sensor because O2 is the chemical formula for oxygen, the oxygen sensor monitors how much unburned oxygen is present in the exhaust as exhaust exits the engine. By monitoring oxygen levels, the sensor provides a means of measuring fuel mixture.
How often should a car oxygen sensor be replaced?
Guidelines for replacing the oxygen sensors in your car, courtesy Bosch.com: The unheated 1 or 2 wire O2 sensors, used in vehicles from mid-1970s through early 1990s, replace every 40,000 to 50,000 miles. Heated 3 and 4 wire O2 sensors, used in the vehicles from mid-1980s through mid-1990s, replace every 60,000 to 70,000 miles.
What happens when the oxygen sensor goes bad in a GMC Yukon?
When an O2 (oxygen) sensor go bad, it’ll cause your GMC Yukon ‘s engine to run less efficiently. Your Yukon can exhibit symptoms when the Oxygen sensor has gone bad. Or, it may exhibit none at all. Often enough, the only sign of the problem at all is the service engine soon light being on.
What to do if your oxygen sensor is bad?
The trouble codes associated with the OBDII scan will reveal which sensor is at fault and why it is bad (at least what the computer thinks is wrong). It is very rare for there to be a problem with an oxygen sensor, and not have the check engine light come on. Here are the most common symptoms of a bad oxygen sensor in your Yukon:
