P0235-17(28) Turbocharger/supercharger boost sensor A circuit- general electrical failure

Hi all,

Thanks for adding me for landyzone. I have Discovery 4 TDV6 L319 and I live in Finland. After 10 minutes from cold start and when I get the car into the motorway with sudden acceleration, red warning light came Performance Restricted. It was cleared when turned off after engine restart. When scanned with IID, I got error P0235-17(28) Turbocharger/supercharger boost sensor A circuit- general electrical failure-circuit voltage above threshold.

Didn't get the error again. Note that the temperature was -17 celsius and the battery is almost 6 years old.
Can you kindly suggest the possible causes?

Thanks for the support.
