Keep your engine's fuel mixture on target with the NTK Oxygen Sensor, manufacturer part number 22129 from NGK's NTK sensor line. An oxygen (O2) sensor sits in the exhaust stream and measures the oxygen content of the exhaust gases, then sends that reading to the engine control module so it can trim the air-fuel ratio for proper combustion and emissions control.
Signs the original sensor may need replacing include an illuminated check engine light, reduced fuel economy, or a rough idle — have the cause diagnosed first, since these symptoms can have other sources; if a failed oxygen sensor is confirmed, this replaces it. Manufacturer part number 22129. Confirm this sensor fits your vehicle using the Buyer's Guide tab before ordering.
