Ok, so these remaining codes are pointing towards the Gas Temperature Sensor. P2033 says the voltage is higher than 4.98v for 2s and P2084 says the voltage has been incorrect for 1500ms.

So the common factor points towards either the gas temperature sensor itself, or the electrical harness.

The Gas Temp Sensor is Item (2) on the Diagram and the Part number is 1618PG (this is a replacement part number)
The Citroen price is £119.98. I've located this genuine one on ebay for £98.99 -

Does one sensor cover both the up and downstream as there's 2 faults stored?

Only one temperature sensor shown at 2. The diagnostics are reporting the wrong voltage values for various times on both the fault codes.

Hey guys.nany thanks for all your help in my dreaded anti pollution fault.it was indeed the exhaust gas temperature sensor. All changed and now for some reason the car is much much smoother. Just waiting for the bill now
