Upstream Oxygen Sensor For Ford F-150, E-Series, Fiesta, Focus - 234-5113

Got a Ford truck or car throwing a check engine light?

Might be your upstream oxygen sensor.

This is a replacement front O2 sensor that fits a bunch of Ford models—F-150, E-150, E-250, E-350, Fiesta, Focus, and more.

It's the upstream sensor, so it's the one before the catalytic converter, monitoring your air-fuel mixture.

Interchange numbers include 8F9Z-9F472-H, 8F9Z9F472H, and DY1185.

It's also known as part 234-5113.

This is a new, unbranded sensor, but it does the job.

One sensor, front placement, plugs right in.

If your engine's running rough or your gas mileage sucks, this little sensor could be the culprit.

Swap it out, clear the codes, and get back to driving smooth.

Keep your Ford breathing right.
