Description

Bosch 17259 oxygen sensor for the 2014-2020 Ford Fusion 4-cylinder 1.5L is an upstream wideband Bosch O2 sensor that reads the air-fuel ratio continuously. It gives the ECU more detailed air-fuel data than a switching sensor, which helps with fuel efficiency and emissions.

Wideband sensor measures the air-fuel ratio across the full lambda range
Reaches operating temperature in under 7 seconds for quick signal availability to the ECU
Built to withstand exhaust streams up to 1,880°F
Metal housing with an integrated heater element and TSP coating that resists vibration, corrosion and contamination

Quick facts

Part: Bosch 17259 oxygen sensor
Fits: 2014-2020 Ford Fusion 4-cylinder 1.5L
Position: Upstream

Condition: New

A failing oxygen sensor can show up as a check engine light, poorer fuel economy or a rough idle, though other faults produce the same signs. Before replacing it, look over the sensor wiring and connector with the engine off and cool for melted insulation or damage, and leave any deeper testing to a shop.

Frequently Asked Questions

Does the 2014-2020 Ford Fusion 4-cylinder 1.5L take this oxygen sensor?

Yes. Bosch 17259 is a direct-fit replacement for the 2014-2020 Ford Fusion 4-cylinder 1.5L, which takes one upstream sensor.

Is this Bosch premium oxygen sensor a wideband or a narrowband type?

It is a wideband type. Bosch 17259 reads the air-fuel ratio continuously across the full lambda range instead of just switching between rich and lean.

Does the Bosch 17259 come with its wiring harness?

Yes. This listing is one oxygen sensor with its wiring harness, and the threads already carry conductive anti-seize.

What thread size and wrench size does this upstream oxygen sensor use?

The thread is M18 - 1.5 and the hex size is 22 mm. Overall length is 12.6 in.

How quickly does this wideband oxygen sensor reach operating temperature?

It reaches operating temperature in under 7 seconds, so the ECU gets a usable signal quickly for closed-loop control.
