Lambda Sensor Peugeot 207

[Chris34]

I am hoping someone can help I have had an anti pollution error come up on my car. I plugged the mini computer error reader in and got the following message ‘PO54 HO2S Heater Resistance Bank 1 Sensor 2’

Is this the correct part to try and fix this problem?
The car is a 58 reg Peugeot 207 1.4 petrol

Your help is appreciated I can’t find a list of parts for this problem anywhere!

No idea what part you need, but I expect there will be plenty of online suppliers who will match your existing part number or work it out from your reg plate. But before you replace the sensor it would be worth confirming that is the fault - be a shame to do all that work and then find it was a wiring fault.
