Walker Products 250-241003 oxygen sensor for the 2014-2020 Fiat 500L 4-cylinder 1.4L and other vehicles measures the oxygen in the exhaust gas to show how efficiently the engine burns fuel. This Walker Products oxygen sensor is a 4-wire, narrow-band design made for its specific application and fitment position.
- Monitors the oxygen content of the exhaust gas and the air-fuel ratio for combustion efficiency
- Measures oxygen levels to help fine-tune the air-fuel mixture for fuel economy
- Electrodes made of a gas-permeable platinum layer
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust
- Monitors exhaust gases to help reduce pollutants
Quick facts
- Part: Walker Products 250-241003 oxygen sensor
- Fits: 2014-2020 Fiat 500L 4-cylinder 1.4L and other vehicles
- Position: Upstream, downstream
- Condition: New
A failing oxygen sensor can show up as rough running, higher fuel consumption, higher exhaust emissions or a lit malfunction indicator light, and newer vehicles may store a fault code for it. Rough running or a warning light can also start elsewhere, so with the engine off and cool, look over the sensor, its wiring harness and the connector for physical damage before you replace anything.
Fits
The 2014-2020 Fiat 500L 4-cylinder 1.4L, the 2015-2018 Jeep Renegade 4-cylinder 1.4L and the 2016-2018 Fiat 500X 4-cylinder 1.4L take this sensor, and so do more vehicles. This listing is one sensor, and the fitment calls for one at the position it is made for.

Frequently Asked Questions
Is this a Jeep Renegade oxygen sensor for the 2015-2018 4-cylinder 1.4L?
Yes. Walker Products 250-241003 fits the 2015-2018 Jeep Renegade 4-cylinder 1.4L. If your car is a different one, look up its year and engine in the "Vehicles it fits" section.
Is the Walker Products 250-241003 a narrow-band or wideband sensor?
It is a narrow-band sensor. Walker Products 250-241003 has 4 wires and an M18 - 1.5 thread.
What does the platinum layer on this oxygen sensor do?
The electrodes are made of a gas-permeable platinum layer. A coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust.
What signs can a worn oxygen sensor show?
A worn sensor can show up as the engine running poorly, higher fuel consumption, higher exhaust emissions or a lit malfunction indicator light. A shop can read any stored fault codes.
What does this oxygen sensor report to the ECU?
It reports the oxygen content of the exhaust gas so the air-fuel ratio can be monitored for combustion efficiency. It also gives the ECU the diagnostic system feedback it requires.
