Faulty O2, who can help?

Malcforrest

Hi guys

I'm needing a bit of help. For awhile my engine management light has been on. I hooked up my laptop to get the code and find out what it is, and it came back with P0141 O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 2)!

Which sensor would this be, before the emission pass through the cat or after?

Thanks

Malc

after cat

unless the lambda is physically unconnected then it is buggered

needs replacing or fitting 02sim in place
