No Power, Clutch Position Sensor.

Posted in an existing thread but couldn’t find it.
Any help is appreciated. Just FYI PCV system is still to be done but...

Managed to leave my parking lights on and ended up with a flat battery. Car was running fine before hand but after jump starting it the main symptom was no power and pronounced hesitation on acceleration, the more I pushed on the accelerator the more it seemed to bog down. (My Cruise control hasn’t worked since I got the car and didn’t investigate it as I don’t have a use for it). Got the AA out as I didn’t have my code reader or tools. Turns out it was the CPS throwing a code.

Replaced it with a new one today but haven’t cleared the code as my mate has my reader and it the power was significantly worse after, has gradually got better after driving for a few miles but still bogs down. Question is does the code need cleared or should it have cleared itself?

You don't mention if you charged the battery with a charger or just driven it to "self charge" via the alternator.

If the latter, maybe the battery does not have sufficient charge?

Low battery voltage can confuse the ECU function. I've had this before - disconnect the battery, charge it fully for at least 12 hours (preferably 24) then reconnect battery and see if you've still got a problem. A full "no power" reset on the ECU then reconnect with full battery voltage often sorts it.
