Check Engine Light – An illuminated check engine light with O2 sensor related fault codes is a clear sign of problems. Poor fuel economy – Reduced gas mileage is one of the most common symptoms of a bad O2 sensor. Rough idle – Engine misfiring caused by inaccurate sensor readings will produce a fluctuating idle.
Oct 30, 2014 · When O2 sensors get old, they don't necessarily go bad, what they do is get lazy. When a good O2 sensor is doing its thing, if you were to look at the readings from it, the numbers go all over the place, from top of the range to bottom of the range and everywhere in between. As the sensor gets old, this jumping of numbers slows down.
Feb 2, 2024 · In conclusion, a bad O2 sensor can indeed cause bad gas mileage by disrupting the air-fuel ratio and leading to inefficient combustion. Recognizing the signs of O2 sensor failure and addressing the issue promptly is crucial for maintaining optimal fuel efficiency and preventing potential engine problems.
Apr 26, 2022 · Those symptoms could also be indications of other problems, but the EPA says that replacing a bad oxygen sensor can improve fuel economy by as much as 40 percent, so clearly that is one place to ...
