OBDII Codes I have a Chevrolet Cobalt Sedan, it has the check engine light on, I took it to get inspected and it came back with these codes: P0014, P0700, and P0973? Can you tell me what these codes mean and what needs to be fixed please?

SOURCE: service engine light

Good Day,

Code P0102 indicates MAF(Mass Air Flow) sensor circuit, low frequency detected

Code P0300 indicates Random Cylider miss fire, meaning missfire in more than one cylinder

The misfire could be a result of the mas air flow sensor being faulty.

Hope this helps for now

Let me know what size motor and if it's 2wd or 4wd and I can get detailed instructions for replacing

you have to know what the code is that your truck putting out your truck has 4 O2 sensors. the trucks computer is smart and the code will tell you witch one is bad but if you replace just one the next one on the same exhaust pipe will probley go bad so its safe to replace all four. the draw back to replaceing all of them is thay cost about 80 bucks for one ACDelco O2 sensor. It has to be done before it will pass Emissions. not a hard part to change about a 7/8 open end wrench will take it off. have fun.
