Toyota Yaris I 1.0 2002 - Where is the B1S1 probe in the Yaris I 1.0 and where i

I am asking for a hint - which probe is B1S1 and which one is B1S2? I'm sorry, but I am standing over the engine and something I can't understand. : /

Thanks a lot for the hints.

B1S1 is the one closer to the head. B1S2 is behind the catalyst.

So it's just that, right?



If so, thank you very much!

I can't see anything higher, so this one. When you unplug the plug, after starting the engine you will have an error from the heater with the description of which probes are the error.

I didn't really think of it - yes, it's this one. In addition, the Bosch replacement has exactly the same length of the cable and the hooks in the same places on the cable.

How to heat it up at home, because it is terribly baked?

Added after 14 [hours] 38 [minutes]:

Generally - it was enough to get back from the route. The engine was well warmed up, I quickly unplugged the probe cable - then I could put on a ring spanner (22 as if it were to be useful to someone) and basically with a strong jerk it came off.

The topic seems to be resolved, thank you for your help.
