o2 heater circuit ???????

Hey!

I have a 1999 F53 with the V10.

I had a check engine light come on ... O2 sensor.

OK, so I replaced both sensors (I new one was 10 year old and the other even older, probably original).

Now I have a new error ... malfunction in O2 heater circuit

Could I have gotten a bad sensor or how can I check for a "real" problem? Is there a fuse for these units? Can I just check for power on the connector? if so, which pins?

Thanks ..... Mike

just to add ... from Bosch to NTK ...

Just an added note ...

I had Bosch sensors in the RV ... in fact, one said Ford / Bosch on it (as I said ... probably original and 20 years old.

I had replaced one 10 years ago with a Bosch.

The local store only had NTK sensors in stock.

They looked different but the parts guys said they were a direct replacement .... are they?
