p0031 HO2S Heater Control Circuit low

Presuming this is the O2 sensor that is gone,

If this is the case ,is it safe to drive the car until i get it repaired
where is the cheapest place to get a new 02 sensor
Would a seconhand one be any use?

Thanks

I have the same issue, have you managed to get one yet if so where did you get it from and was it hard to fit

hi

I have not had a chance to get this part yet

Hi

Am i right in saying that there are two 02 sensors, got one of them replaced and there is still the same warning light, subaru garage in Ireland quoting me €400 for the other 02 sensor

any ideas?

There's two sensors. if you've replaced the rear one then its been an expensive mistake.
If you've replaced the front one and still get the error then it's a wiring problem.
