P0131 Fix 2012-18 Ford Focus O2 Sensor Replacement

[@patmcwilliamsmusic]

thanks for the video. My son's 2017 Focus has this same issue but also has a P0135, P2237 , and P0131 code. The O2 was replaced about 6 months ago but has since returned. Any help would be appreciated.

7/8 is not sitting on the sensor correctly, and I cannot get it loose.

Hi do you know if crankshaft sensor would prevent no crank

[@BLUECOLLARGARAGE]

Is it cranking and just not starting?

Some 2012 ford focus need dy1199 part not dy1185

Hi was it no start issue

[@BLUECOLLARGARAGE]

No it started just fine. Check engine light came on and was getting poor fuel mileage.

If your engine doesn't start, it's unlikely to be an oxygen sensor issue, because oxygen sensors are not even used on engine start, they come on a bit later (how much later depends on car and sensor), because they need to heat up to working temperature first to give reliable data.
