How do I fine out about my engine light on

What code did autozone say was in the PCM ? Did it have the word circuit in the discripition ? Maybe wiring issue or PCM etc...

First step is to check the ODBII codes which will tell you what the car's computer is seeing as a problem. Autozone and many other car parts stores will do this check for you for free. Only takes 5 minutes.

the oil light can be from a bad oil sending unit or a faulty oil pump in the engine, i would have the pressure tested ASAP at a shop.
once the issue causing the codes that turn on the check engine light are fixed it should be reset by the mechanic that did the work.

It is the APP sensors , Your vehicle has electronic throttle control . P2122 Throttle Pedal Position Sensor Switch Circuit Low Your best bet would be to take it to a qualified repair shop .

code scanners at autozone doesent really tell the problem, they are more of a guess than anything. best way to find the right one is take it to the shop and have it put on the computer to find the true problem and autozone should be able to tell you what sensors those codes stand for....hope this helps...

engine light is telling you somthing is wrong..very possable a hose may have been nocked loose during your service ( if a lube shop serviced it fast they may have knocked off a evap line checking the air filter.. stop into autozone and they will pull the code for you for free..need to know why the light is on before we can go any further

You must get the error code read for the check engine light in order to get helped here. Bring your vehicle to a local autozone to have your vehicles computer scanned, its free or local shop (most charge for this). Post the codes on fixya for further assistance.

I sugges visit any autozone or shop to read the fault codes, with scanner tools; weith this number fault code we'll can send other details about this wrong.

Keep in tounch.

you need to have the codes read by a shop or if you go to Autozone they check them for free.
