Description

Walker Products 250-241091 oxygen sensor for the 2019-2025 Audi Q3 4-cylinder 2.0L measures the oxygen content of the exhaust gas. This Walker Products oxygen sensor is a direct-fit, narrow-band unit made for its specific application and fitment position.

Narrow-band design with 4 wires
Electrodes made of a gas-permeable platinum layer
Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
Monitors the air-fuel ratio to show combustion efficiency
Gives the ECU the diagnostic feedback the application requires

Quick facts

Part: Walker Products 250-241091 oxygen sensor
Fits: 2019-2025 Audi Q3 4-cylinder 2.0L
Position: Downstream
Condition: New

A failing sensor can show up as rough running, higher fuel use or a malfunction indicator light, though other problems can look just like these. Before replacing it, look over the sensor, wiring harness and connector for physical damage with the engine off and cool; if a failed downstream sensor is the cause, this one replaces it.

Fits

This downstream sensor fits the 2019-2025 Audi Q3 4-cylinder 2.0L (L4-2.0L), which takes one. This listing is one sensor.

Frequently Asked Questions

Is this the oxygen sensor for a 2019-2025 Audi Q3 4-cylinder 2.0L?

Yes. Walker Products 250-241091 is a direct-fit sensor for the 2019-2025 Audi Q3 4-cylinder 2.0L (L4-2.0L), and that engine takes one.

Is this narrow-band oxygen sensor upstream or downstream?

It is a downstream sensor. Walker Products 250-241091 is a narrow-band design with 4 wires.

What thread size does this oxygen sensor have?

The thread is M18 - 1.5, and the sensor is a threaded type.

Will a bad oxygen sensor set a fault code?

Newer vehicles store fault codes in the ECU, and some relate to the affected sensor and its associated systems. A shop can read the codes.

What is the platinum coating on this oxygen sensor for?

The electrodes are made of a gas-permeable platinum layer. The coating keeps combustion residue and particulates in the exhaust from contaminating and eroding the electrode surfaces.
