Give your engine computer the exhaust-oxygen feedback it relies on with the Walker Products 350-34615 Oxygen Sensor. It is a 4-wire, direct-fit, narrow-band sensor that measures combustion efficiency from the amount of oxygen in the exhaust gas. It fits many vehicles, among them the 2006-2010 Hyundai Sonata, 2007-2009 Kia Sorento and 2007-2009 Hyundai Santa Fe. See the "Vehicles it fits" section for the full list and engine details.
Walker Products engineered its engine management and oxygen/air-fuel sensors as OE replacements for many vehicles worldwide. Each part number is built for its specific application and fitment position, and it is designed to give the ECU the diagnostic feedback it requires. For this Walker Products oxygen sensor, the listed positions vary by application. They include upstream (front, rear and left) and downstream (front, left and right) locations.
- Exhaust oxygen monitoring: determines the oxygen content of the exhaust gas and monitors the air-fuel ratio for combustion efficiency.
- Protective coating: designed to prevent combustion residue and exhaust particulates from contaminating and eroding the electrode surfaces.
- Platinum electrodes: the electrodes are made of a gas-permeable platinum layer.
- Mixture feedback: measures oxygen levels so the air-fuel mixture can be fine-tuned, which helps support normal fuel economy and lower exhaust pollutants.
Signs an oxygen sensor may need replacing include:
- poor engine running
- increased fuel consumption or emissions
- an illuminated malfunction indicator light (MIL)
Newer vehicles may also store related fault codes. These symptoms can have other causes, so diagnose the problem first, and inspect the sensor, wiring harness and connector for physical damage. Walker Products has supplied engine management sensors since 1946 and is an ISO 9001/TS 16949 certified company.
Frequently Asked Questions
Will this 02 sensor fit my 2006-2010 Hyundai Sonata?
Yes, it is listed as a direct-fit application for the 2006-2010 Hyundai Sonata. See the "Vehicles it fits" section for engine details.
What other vehicles does this oxygen sensor fit?
It fits many vehicles, including the 2007-2009 Kia Sorento and the 2007-2009 Hyundai Santa Fe. The "Vehicles it fits" section has the full list.
What does an oxygen sensor do?
It determines the oxygen content of the exhaust gas. The ECU uses that reading to monitor the air-fuel ratio and fine-tune the mixture for combustion efficiency.
What type of sensor is the Walker Products 350-34615?
It is a 4-wire, direct-fit, narrow-band oxygen sensor. Its electrodes are made of a gas-permeable platinum layer, and a coating is designed to protect the electrode surfaces from combustion residue.
What are the signs an oxygen sensor may need replacing?
Possible signs include poor running, higher fuel consumption or emissions, a lit malfunction indicator light and stored fault codes. These can have other causes, so diagnose the problem before replacing the sensor.
