Our take on the Bosch 16246 Oxygen Sensor

The Bosch 16246 is a downstream oxygen sensor for the 2013–2017 Ford Focus with the 2.0L engine. It is a narrowband, threaded 18mm sensor with an OE-style connector, so it plugs into the factory harness without splicing. Bosch lists accuracy as meeting or exceeding OE specs. At $32.97 at eBay as of November 3, 2026, it sits at the low end of what this part typically sells for, well under dealer prices.

Best for2013–2017 Ford Focus 2.0L owners with a check-engine light for the downstream seDIYers replacing a failed sensor with an OE-fit plugHigh-mileage Focus owners chasing poor fuel economy or emissions failures
Pros
  • Direct-fit OE connector, no splicing or adapter needed
  • Narrowband output matches the factory sensor's signal
  • Threaded 18mm body installs with a standard oxygen sensor socket
  • Bosch is a common OE supplier, so fit and calibration are predictable
  • Low price for a part that can fix a check-engine light and emissions test
Cons
  • Fits only the 2013–2017 Focus 2.0L; not universal
  • Narrowband only, so not a wideband upgrade part
  • No socket or anti-seize included beyond the connector
  • Sensor life depends on upstream oil or coolant leaks being fixed first

Questions and answers

Is the Bosch 16246 worth it over a dealer sensor?
For a stock 2013–2017 Focus 2.0L, yes. It is a direct-fit narrowband sensor at a fraction of the dealer price, and Bosch supplies OE sensors for many Ford applications.
Will it fit my Focus?
It is listed for the 2013–2017 Ford Focus with the 2.0L engine. Check your engine and sensor position before ordering, since other engines and years use different parts.
Do I need any special tools?
A 22mm oxygen sensor socket or a 7/8-inch wrench gets the old sensor out. The new one threads in by hand and tightens to the factory torque spec.
What is in the box?
One sensor with the OE connector attached. No socket, anti-seize or instructions are included.
When is it cheapest?
Oxygen sensors rarely go on deep sale. The $32.97 eBay price as of November 3, 2026 is already near the bottom of its range, so waiting rarely saves much.
Will it fix my check-engine light?
It fixes codes caused by a failed downstream sensor. If the code comes from a wiring fault, exhaust leak or rich-running engine, a new sensor will not solve it.
