Honda Accord Oxygen Sensor 36531-R70 Direct Plug-in Replacement No Programming Installation

If your Honda Accord shows MIL, notably higher fuel consumption, idle instability, or weak acceleration, this usually indicates aged or failed oxygen sensor unable to monitor exhaust oxygen accurately. When functioning, oxygen sensor feeds ECU with exhaust oxygen concentration to precisely control air-fuel ratio for optimal combustion and emissions. OEM number 36531-R70; fits multiple Honda Accord models including 2008-2012 2.4L and 3.5L variants. Installation: direct replacement of OEM sensor, no ECU programming; operate with engine cool, ensure threads are clean and torqued to about 45 Nm to prevent leaks and signal loss.
