02 sensor fault p0141

[howie1987]

Hi i got a new gasket for the cat then i thought i needed a new front sensor so got that then fitted it plugged it in to the computer and cleared it but light came back on and this still comes up

p0141 02 sensor heater circuit malfunction (bank 1 sensor 2)

Have i got the wrong o2 sensor? and its the back one i need or can there be anything else wrong like the new o2 sensor isnt working cause am pretty sure that is the front sensor?

Thanks

Sensor 2 is the second of the two. Post cat.

Very common failure

So its the one nearest the back of the car i need? i feel a bit daft now allways getting wrong parts.

Thanks thought the gasket was a cheap fix aswell

I take it there two different o2 sensors, could i just put my front one back in and put the new one in the back? or is totally different sensor.

I'm not sure for the EP3 if I am honest.

I know the DC5 has 2 different sensors.

But yes, there are 2 sensors, one before the CAT and one after it.

Thanks for the help. the old one i took out looks in bad nick anyway so i'll just get a new rear one anyway. cheers
