Hiya all your codes are pointing at your emmissions evaporative control system. hope this helps you ?
P0452 is fuel tank pressure sensor circuit fault. I have never heard of a P0440, but 400 series codes are in the emmissions, i.e., EGR and Evap system. I would try to fix the 452 and see if the 440 goes away with it.
12345
they cant say it
Can anyone tell me what press codes are
This is a used code (don't tell anyone!)THIS is the horse code it is 72hxf254jm46
Auto Zone (and I assume other auto parts stores) will usually read the OBD codes (for free) and tell you what the code means. I found P0440 online for many other cars (and I think the codes are standard across most manufacturers) to mean there is an "Evaporative Emmision Control System" problem. This could be as simple as replacing the gas filler cap (the EECS is a pressurized system - when the gas cap doesn't hold the pressure it can cause an erroneous P0440 code.
no but if you know one please tell me
i dont want to tell anyone the code cause it's secret
the code comes with the book; noway am i or anyone else gonna tell you our codes by the way
Trouble code P0721 means:Output speed sensor circuit range/performance
They generally set a trouble code and the check engine light illuminates.
