the code for my car was P0028 and I am wondering if it's possible that a car part is ruined and I need to get a new one or if I just need to change the oil. please respond ASAP. thank you.
You could start by changing the engine oil and filter, and clearing the engine code by disconnecting the car battery (30min or so) if you dont have an obd-II reader to clear the code.
if the problem is still there the sensor might be bad if the harness is not open or shorted.
