Hi Everyone,

Today I was driving to work and the CEL turned on, after scanning I've gotten two codes, P014A and P2098. Any thoughts on what this means? Maybe a bad o2 sensor?

2011 Mustang GT
Axle-back exhaust, cold air intake and tune. All done over a year and a half ago
It's ~7500miles since last oil change

Now that I think back... I was driving to work on Monday and I heard a loud pop sound, as if an acorn drooped on your car hood. Going on the highway about 75, probably unrelated...

Any thoughts would be appreciated, google didn't show much.

Thanks!

/edit

ok so I did some digging, these are the explanation for codes on 2009-2010 mustang GT's. I guess there's an exhaust leak hear the HO2S. Is that the oxygen sensor?

Trouble Code: P2098
Post Catalyst Fuel Trim System Too Lean (Bank 2)
Possible Causes:
Loose connection, and damaged or corroded terminals
Exhaust leaks
Contaminated HO2S

Trouble Code: P014A
Sensor Delayed Response - Rich to Lean (Bank 2, Sensor 2)
Possible Causes:
Exhaust leaks before or near the HO2S
Aftermarket exhaust accessories or performance modifications
Ethanol content in the fuel
Circuit intermittent
Damaged HO2S
