Re-occuring P2A00 code 09' Toyota Yaris UK

Question

Hello, we have an 09 plate Toyota Yaris (UK) and have a P2A00 code that re-occurs every so often, any ideas? i think it could be the Lambda sensor from a bit of googling?

It tends to happen after being out in the wet weather but then dissapears again eventually.

You probably need a new Air fuel Ratio (A/F) Bank 1 Sensor 1.
