Default Sentra error code : 2-11-10-10 ???


I own a 07' Sentra (with CVT). Since a few days the Service Engine Soon lights up. I used the well-known procedure to 'read' the error code without a code reader and I got : 2 longs, 11 shorts, 10 shorts, and 10 shorts.
I know 10 stands for '0', but what about 11????

According to what I read I guess this code is about Nox Trap or O2 sensor.

Moreover I have (kind of) rattling noise on (hard) acceleration. According to owner manual (page 2-14) this might be caused by engine misfire. No idea what it means.

Can anyone help me finding the exact error code, and tell me what is engine misfire, and what I should check to fix it? Spark plugs? Wires? Fuel filter? My car has now ~225,000 km (~140,000 miles).

Thanks for your help.

I'm thinking your trouble code is P2A00, which is an air/fuel ratio sensor code. Misfiring could cause this code to set, so it may not be the actual sensor. A misfire is when a cylinder doesn't fire, which can be caused by a bad ignition coil or circuit, bad fuel injector or circuit, low compression, fouled or faulty spark plug, to name the most common causes.
