I've had this code and explanation a couple of times now so I'm assuming I should get it sorted.

"P0133 sensor circuit slow response bank 1 sensor 1"

I've cleared the code but it comes back. I especially notice it comes when the car is under load ie when I put my foot down a bit. It can go for a long run, just under normal load and nothing!

Any ideas guys? I know the code and explanation will probably be obvious to most of you here - but to me, uh uh. Is this easy to sort?

 

May well just need to replace the sensor.
