General P0115 code

[BANKIEBEAR]

Hi guys I have a 55 plate mk2 punto which failed it's MOT due to overheating during test I figured it out to be the fan which I replaced but now I have the eml light on & using a wee ODB II scanner it shows up the code P0115 I haven't ran the engine up to temp since replacing the fan I did disconnect the temp sensor plug & the fan kicks in & reconnected the plug & it(fan) goes off which is fine the gauge sits at the mid point but the scanner won't let me erase the code.
Is there any way of erasing the code before I put it in for a retest as it would fail again due to a warning light.
Any advice would be appreciated thanks

Hi

Would it not clear the code?

Was it saying coolant over temperature..?

No everytime I hit erase it would say erase fail.
Would I benefit from running the engine on idle to see if the sensor kicks in the fan or would it need a diagnostic laptop plugged in to clear it as I can't take it for a drive due to the failed mot

Hi

Worth disconnecting battery overnight

Might just reset something
