also have Check charging system, have new battery Alternator

Question

Have a 2008 mustang GT says low oil pressure, check charging system, code 102 and 0443 Battery is new, alternator new. Do I have a short in wiring?

Answer 1

P0102 is related to the mass air flow sensor you can try to clean it with mass air flow sensor cleaner and P0443 is related to the EVAP system (you will have to check for loose, cracked or broken hoses be the engine bay or the purge control valve might be bad.

nothing is related to oil pressure, have you check the oil level and has the oil been replaced in the last 4k miles? if not replace or check the oil and make sure you use 5w-20 the wrong oil weight will cause oil pressure issues.

are you using the orginal alternator? new or rebuilt? 

I would check it again at idle and under load
