Keep the ECU's fuel trim reading accurately with the Walker Products Oxygen Sensor 350-35148, a wide-band, heated 5-wire upstream sensor. It installs as a direct-fit replacement for the listed applications including the 2018-2024 Jaguar E-PACE [L4-2.0L], 2018-2025 Jaguar F-PACE [L4-2.0L], and multiple Land Rover models with the L4-2.0L and V8-5.0L engines — see the Buyer's Guide tab for the full list.
Mounted upstream (ahead of the catalytic converter), it measures the oxygen content of the exhaust gas to gauge combustion efficiency and reports the air-fuel ratio back to the ECU so it can fine-tune fueling for cleaner emissions and supported fuel economy.
Wide-band, heated, 5-wire design: reads the air-fuel ratio across a broad range and warms quickly for faster feedback.
Platinum electrode layer: electrodes use a gas-permeable platinum layer, with a coating that helps guard the electrode surfaces against contamination and erosion from combustion residue and particulates.
Threaded install: screws into the exhaust with a 22 mm wrench size; overall length 11.81 in.
Sensor quantity varies by engine and application, so some vehicles use two upstream sensors (left and right banks); this listing is for one sensor. Manufacturer part number 350-35148 (also 35035148) · Country of origin: United States.
Frequently Asked Questions
What does this oxygen sensor do?
It measures the oxygen content of the exhaust gas upstream of the catalytic converter to gauge combustion efficiency, then reports the air-fuel ratio to the ECU so it can adjust fueling.
Is this a heated wide-band sensor?
Yes. It is a wide-band, heated 5-wire oxygen sensor, allowing it to read the air-fuel ratio across a broad range and reach operating temperature quickly.
Where does it mount?
It is an upstream sensor, installed ahead of the catalytic converter. It threads into the exhaust and uses a 22 mm wrench size, with an overall length of 11.81 in.
How many sensors does my vehicle need?
Quantity varies by engine and application; some vehicles use two upstream sensors for the left and right banks. This listing is for one sensor, so order the quantity your application requires.
What are signs this sensor may need replacing?
A failing sensor may cause the engine to run poorly, raise fuel consumption or emissions, or illuminate the malfunction indicator light. Diagnose the cause first, and inspect the sensor, harness, and connector for damage.
