The current engine is controlled by a computer, so the air-fuel ratio is measured by the amount of oxygen remaining after combustion.
Symptoms of an O2 sensor malfunction include decreased fuel economy, increased soot inside the muffler, and the engine warning light turning on.
Even if the malfunction is left unaddressed, it may not cause driving problems, but the burden will increase and it will eventually break down.
Even if it is not malfunctioning, the replacement time for an O2 sensor is approximately 5 years.
Caution is required if the mileage is high or the vehicle is old.
Costs can be reduced by using reasonably priced aftermarket parts that are equivalent to genuine parts, rather than expensive genuine parts for replacement.
*Please note that we do not provide support or respond to inquiries regarding installation.
*Instruction manuals, etc. are not included.
*If you are not confident in installing it yourself, we recommend having it installed by a professional or a mechanic.
*Please be sure to confirm compatibility using the genuine part number.
