HELP 1999 S70 o2 sensor wires S70 1999

I need to confirm the o2 sensor wires for my 99 non-turbo S70. Are the following correct?

signal wire - blue

ground wire - white

black wires (2) - heater

Yes, I too am trying to use a Bosch universal o2 replacement #15738 and the CEL keeps coming back on. Replaced both front and rear sensors but codes P0130, P0135 and even P0136 show up in varying order, combination and number...

Oddly enough, car runs fine. Going to remove battery ground for the magic 10 minutes now... (read that tonight on Bay 13)

Help!

Let me add to my question... will vaccum line problems translate to O2 code errors???

Of course vacuum problems lead to error codes. Usually when cleared, the error will come back in about 1 week of daily driving, if it is a vacuum problem. If you have the wires crossed, you will not be able to clear the code.

Bear with me Klaus...

I guess to try and ask the question more specifically, if my OBDII scanner is showing CEL codes for O2 sensors can it be vaccum line problems?

Will it harm anything if I switch the two wires (blue & white) on the O2 sensor to see if it is that simple?

Never having put on a non-OEM sensor, I cannot answer the second question.

And, yes, vacuum leaks cause those kinds of errors.
