Ph1 Spider Lambda

Hi, I am after some advice. My Spider failed its MOT on emissions on Saturday. The guy said its not often they see one so bad!
I have hooked it up to Anyecu and its come up with the following errors:
Lambda sensor integrator - open circuit
Lambda sensor - open/short circuit
I also noticed that the lambda sensor spent most of its time 'cold' so I measured the heat coil resistance which was just out of spec (lower resistance).
Is it likley that the lambda sensor is the cause? Or is something else creating conditions the Integrator can't cope with?
The Spider is a Ph1 2.0ts with 108k miles
Many thanks in advance.

It says open circuit so check the wiring and connector block to the left of the fuel rail. But could also be faulty lambda. I know that when I've monitored the lambda in real time using MES it cycled through rich then lean every few seconds.

If the heater isn't working then yes I would think the lambda is the cause.
