Why do some cars burn more gas than others?
Why do some cars burn more gas than others?
This is because all the vehicles are least efficient and most polluting at thew start of their journey and during short trips. Trips which are less than 5kms don’t let the engine to reach its optimum operating temperature, therefore, the engine uses more fuel.
What happens if you have a bad O2 sensor?
If the fuel mixture has too much oxygen, the engine is burning lean. If the fuel mixture has too little oxygen, the engine is burning rich. In either case, the ECU needs this information in order to adjust the fuel/oxygen ratio. If your car has a defective o2 sensor, it will not run efficiently.
How does a faulty oxygen sensor affect gas mileage?
A faulty oxygen sensor can have one of the most detrimental effects on gas mileage. Fuel efficiency losses of up to 40% are not uncommon if your O2 sensor is damaged or malfunctioning.
Where is the O2 oxygen sensor in the engine?
Also, The (O2) Oxygen Sensor is not able to measure the air or the fuel entering the engine. Because, the (O2) Oxygen Sensor is located in the exhaust and that where it reads the actual oxygen content in the exhaust. Depending on the year; make and model of your vehicle you could have anywhere from one to four (O2) Oxygen Sensors.
What should the voltage be on the O2 sensor?
To perform the actual test, start the car again and check the voltmeter’s voltage readings. The o2 sensor’s voltage should fluctuate within the 100mV – 900mV (0.10V to 0.90V) range. If it is within this range, the o2 sensor is operating normally and you can stop testing.
What happens if the O2 sensor fails to function?
Finally, if your (O2) sensor fails to function properly; your engine management computer cannot determine the air to fuel ratio. Therefore, the engine is forced to guess how much fuel to use. Resulting, in a polluted engine and a poorly functioning vehicle. It’s true that many of these symptoms could be caused by various problems.
Can a bad O2 sensor cause an illuminated check engine light?
Faulty O2 sensors are a common cause of illuminated Check Engine Lights. Still, because the light may indicate a variety of other problems, it is important to watch for bad O2 sensor symptoms. If you notice any, repairing the problem as quickly as possible is a good idea to prevent further trouble.
Also, The (O2) Oxygen Sensor is not able to measure the air or the fuel entering the engine.

Depending on the year; make and model of your vehicle you could have anywhere from one to four (O2) Oxygen Sensors.
When to replace an oxygen sensor for poor fuel economy?
If your fuel economy has dropped significantly from its stock rating and all other causes have been ruled out such as vacuum leaks, exhaust restrictions, etc. then it is a good possibility your oxygen sensor is to blame. 2. What sensors to buy When replacing oxygen sensors we recommend not straying from manufacturer recommended replacement units.
