· Their purpose is simple, to prevent dirt, debris, and dust from entering the gas tank; as well as providing a reliable seal. The cap also plays an important role in the operation of the vehicle’s (EVAP) emissions system. The (EVAP) is designed to capture and reuse fuel vapors from the gas tank. Because, the cap is frequently removed, every time fuel is added, it can wear out.
Once the vehicle has been started, the engine oil pressure, coolant level and temperature, transmission status, and fuel level are all sampled by car engine sensors, and their status is reported to the driver, sometimes using traditional analog gauges but more commonly through a general “systems OK” message. Some cars alert the driver only when there is something wrong, illuminating a “Check Engine” light to tell you that all is not well.
Cars with O2 sensors have a minimum of one sensor in front of the catalytic converter, as well as one in each of the car’s exhaust manifold. The actual number of oxygen sensors for a car depends on the year, make, model and engine. However, most of the later model vehicles have four oxygen sensors. Note the following specific vehicles that have four oxygen sensors:
Sensors can be placed at the most suitable place, and their data used by several ECUs. For example, outdoor temperature sensors (traditionally placed in the front) can be placed in the outside mirrors, avoiding heating by the engine, and data used by the engine, the climate control, and the driver display. In recent years, the LIN bus standard has been introduced to complement CAN for non ...

Most modern car engines are fitted with an array of different sensors, which gather data to calculate a perfect air-fuel mixture for the best fuel economy in all situations. Since the late 1980s and early 1990s, most vehicle's engines and drivetrains (the system that connects the transmission to the drive axles) have been controlled by a central processor and sensors.
They are used in cars made for many other countries as well. When the oxygen sensor in your car goes bad, your car runs differently. This is a story of my experiences with the oxygen sensor in my car. Your mileage may vary. Update! See the bottom of the page for info on cars with multiple O2 sensors! Background info: Gasoline engines run best when the air-fuel mixture is correct. The air-fuel ...
· Most cars have an oxygen sensor and a throttle position sensor, but parking sensors are optional. by Tim Charlet on November 17, 2015. Professional mechanics agree that one of the most important evolutions to come about in recent years is the expansion of sensors to monitor mechanical systems. These sensors are responsible for continuously ...
· So, based on this, the car can continue operating on the other sensors alone such as the air flow sensor. However, if both the air flow sensor and the O2 sensor fail at the same time, you may be in trouble (unless the car has a real throttle position sensor and not just an on/off idle switch, but that can fail too... -- modern cars typically have a real throttle position sensor or two as they ...
