Walker Products Oxygen Sensor P/N:250-24493
Walker Products 250-241045 oxygen sensor for the 2018-2025 Alfa Romeo Stelvio 4-cylinder 2.0L and other vehicles measures the oxygen content of the exhaust gas. It is made for its specific application and fitment position, and it gives the ECU the diagnostic feedback the system needs.
A worn sensor can show up as rough running, higher fuel use or a lit malfunction indicator light, though a damaged wiring harness or connector can also be behind them, so inspect both for physical damage with the engine off and cool before you replace the sensor.
This downstream oxygen sensor is a direct fit for the 2018-2025 Alfa Romeo Stelvio 4-cylinder 2.0L, the 2017-2023 Alfa Romeo Giulia 4-cylinder 2.0L and the 2012-2019 Fiat 500 4-cylinder 1.4L, and the downstream position on each calls for one sensor.
Fit and size
Build and materials
Is this an oxygen sensor for the 2012-2019 Fiat 500 4-cylinder 1.4L?
Yes. Walker Products 250-241045 is a direct-fit downstream oxygen sensor for the 2012-2019 Fiat 500 4-cylinder 1.4L, and that car takes one.
Is the Walker Products 250-241045 an upstream or downstream sensor?
Downstream. Walker Products 250-241045 is a narrow-band oxygen sensor made for the downstream position.
What does this Walker Products oxygen sensor measure?
It measures the oxygen content of the exhaust gas, which lets the air-fuel ratio be monitored for combustion efficiency.
Does this narrow-band oxygen sensor have platinum electrodes?
Yes. The electrodes carry a gas-permeable platinum layer, and a coating protects their surfaces from contamination and erosion by combustion residue and particulates.
How many wires does this oxygen sensor have?
This sensor has 4 wires and is a narrow-band design.
