Code P014C, P014D

My questions is this code referring to the oxygen sensor? And is this the first O2 sensor or the one after the cat? Any help would be appreciated.

also, I’m not sure what the C1201 code is about.

And a gratuitous Yuengling shot.

Sorry the picture of Yuengling was supposed to be last and correctly aligned. Oh well. You get the idea.

 

The slow response codes are typically a failing sensor providing there are no exhaust leaks upstream or near the sensor, they are referring to the upstream (before the converter) Air/Fuel Ratio sensor.
The downstream sensor is a standard oxygen sensor, the upstream is referred to a an AFR (Air/Fuel Ratio) sensor.
Toyota uses Denso sensors so make sure you get the correct one and beware of counterfeits on Amazon & Ebay.

The C1201 in the ABS module just means the there's a trouble code in the PCM, it will self clear once the PCM codes are fixed.

 

Thank you very much!
