o2 sensor 850

Hello

I have solved it finally the engine B5252 has a wide range lambda sensor which measures voltage from 0 to 5 it is nothing more then a more precise measurment due to the larger scale then the previous range 0 to 1.

You can fit in a:

Univeral Tytania sensor ( 4 wires are )

= red (+12 volts ) heater
= white( ground ) heater
= Black (signal out)
= Yellow ( ref in )

In fact the engine B5252 from 1993 to 1997 has the symbol used by NTK as N2H25 which correspond to the original no from the manufacurer as 9207999 used by Volvo after the chasis above 60000 something, before that it was 9207998 but all functions are the same
