Hummer Oxygen Sensor Parts

Hummer Oxygen Sensor

Hummer oxygen sensor is an important part in any Hummer vehicles. The Hummer oxygen sensor is also known as lambda sensor or as O2 sensor. It is an electronic device that is used to measure the ratio of oxygen (O2) in the gas or liquid of a vehicle's engine. The Hummer oxygen sensors controls the modern electronic fuel injection and emission process. As it determines the proportion of air and fuel. Based on the result, rich or weak, the Hummer oxygen sensor helps in injection of fuel and emission. It is most commonly used in engines of internal combustion type. In this type of engines, the Hummer oxygen sensor measures the concentration of oxygen in the exhaust gas.

When the engine is loaded heavily, the output of the oxygen sensor must be ignored. So, the output from the oxygen sensor is ignored, automatically providing the right amount of fuel to protect the engine. This is referred to an engine running in 'open-loop mode'. In this state, any changes are made in the sensor will be ignored. If there is any malfunction in the oxygen sensor, then you have to replace it with a new one as soon as possible. Else due to the failure of ignoring oxygen sensor automatically, the engine may be damaged. This will trouble you more and so it is recommended to check the function of the Hummer oxygen sensor on a regular basis.
