HO2S Error Code

[Colourfyre]

Hi,

I got in the car this evening and had the cruise control blinking at me the whole drive home, no check engine light and no unusual behaviour. I have checked it with the scanner and I am getting 'P0030 HO2S Heater control circuit bank 1 sensor 1' come up as pending codes. I cleared them but five mins of running and the code reappeared.

Ive had a bit of a look around and this seems like the oxygen sensor will need replacing? I will check the wires/plug and fuse SBF-5 (read it somewhere else) in the morning but just wondering if that sounds right and if anyone else has any insight?

Ps. Does anyone know the precise part number of the front oxygen sensor? (NZ new 2005 2.5i legacy)

Sounds like you've got it sussed, grab the part number from here:

All sorted and ordered, turned out to be a 22641-AA230.

And fixed, $140 out of pocket but a nice new Oxygen sensor and I've got no more codes and confirmation that the engine computer has recognised the Oxygen sensor heater has been working!
