Does the error code need to be reset after fitting new sensor as no change in power loss?

Question

Had race out after loss of power. Ecu gave lots of error codes but mechanic thought because I was still using car that it would generate more codes. So all codes were deleted and car driven a short distance. On plugging back in there was 1 code. P0238. I have replaced the turbo boost sensor but nothing has changed. Car is an 06 1.6 tdci focus

Answer 1

Yes it's if there was a code for that sensor before you replaced it it will need to be cleared once you replace it.
