Every Volvo car proudly bears an assurance of safety. Volvo has been under the limelight for many years now because of their innovations when it comes to safety. Volvo, a famous Swedish car brand, was officialy born on April 14, 1927 in Gothenburg, Sweden. It was found by Assar Gabrielsson and Gustaf Larsson. Volvo is a Latin word which literally means “I roll.” It is no doubt that a Volvo car is made of car parts that have met the highest of standards. However, due to constant use, these parts should the proper maintenance they need in order to function well. The Volvo oxygen sensor is a small sensor inserted into the exhaust system of a petrol engine to measure the concentration of oxygen remaining in the exhaust gas to allow an electronic control unit (ECU) to control the efficiency of the combustion process in the engine. In much simpler terms, it detects whether the air and gasoline mixture is too lean (too littler fuel) or too rich (too much fuel. A mixture is lean if there is excess air and this could cause nitrogen-oxide pollutants. A mixture is rich if there is less air and this is not good since it the unburned fuels can greatly contribute to pollution. The perfect ratio of air and gasoline that is 14.7:1 in most vehicles. There are two types of Volvo oxygen sensors that are commonly used today. First is the single wire oxygen sensor and second is the heated oxygen sensor, which has a built-in heating ingredient designed to maintain an engine's ideal operating temperature. There are several factors that could contribute to the failure of a Volvo oxygen sensor. One can be normal wearing out due to use and the other once is the heavy use of leaded fuels. Among the symptoms of an oxygen sensor failure is the loss of power of the engine or it may not seem to respond quickly. Another possible sign that could suggest a failure is an increase amount of fuel consumption than the usual even if a car has already undergone some tune-up processes. At least four factors need to be considered in order to ensure a longer life for a Volvo oxygen sensor. First is good electrical connections since the sensor generates low currents. Second is the outside air supply since air must circulate to the internal portion of the sensor. Third is proper operating temperature. The ECU only recognizes sensor signals only when the temperature is already 316 C. Fourth is the use of leaded gasolines since common use of these can damage the oxygen sensor quickly.
