02 sensors

[Haydenj]

Hi

I've had my error codes diagnosed in my 04 VZ and it's been diagnosed as the o2 sensors. I replaced sensor "one" and now it's sensor "two" that isn't working (which I'll replace) but once this is replaced I'm assuming 3 and 4 will start playing up. Any idea where 3 and 4 would be as I can't seem to locate them?

They dont exactly go as sensor 1, 2, 3 and 4.
They go by bank and position.

Sensor 1 on Bank 1 and Bank 2 are on the exhaust manifolds.
Sensor 2 on Bank 1 and Bank 2 are just after the cat converters.

Hope that helps.

Whoever scanned it should have told you which sensor on which bank was crook.
For what it is costing you replacing sensors you probably don't need to replace, buy a cheap scanner under $100 and scan it yourself in future.
I have a scanner sitting in the glove box. It cost $60 at Aldi and does everything I need.
They plug in under the steering column.

just change the two front ones, if you have to, cut wire off, 22mm ring spanner to get the o2 sensor out easy then get the code cleared see what happens i only had to change the front ones might want to spray with wd40 first

‘04 VZ should only have two pre cat sensors.

Maybe SV6 had 4?
