Exclamation Cylinder misfire! HELP!

Hello there,

My 2009 base Fit gave me a engine light this morning... i am looking for some help with finding the problem.

I used my OBD2 and it gave me these 3 codes (in the picture) :
P0302-cylinder 2 misfire detected
P0113-intake air temperature sensor 1 circuit high input
P0102-mass or volume air flow circuit low input

Has this ever happen to you? If so, please help me with any information you have. Also i am open to testing theories you may have.

Thanks in advance!

My .02

I'm not as knowledgeable as some on here, but I think the maf sensor need cleaning or replacing. Get a can of maf sensor cleaner and give it a shot, disconnect the battery for 10 min whike cleaning the sensor. Be sure to have the radio audio code ready when you reconnect the battery.

Also, and this will be tricky and a touch irresponsible, try placing your fingers on top of each coil pack while the engine is running. You should feel a vibration but nothing pulsating. If you do, especially on cylinder 2, the plugs might be lose.

But I think the sensor might be going bad leading to the engine misfiring. Check your air filter also since you're removing the sensor to clean it,

Thank you so much Santiad! I found the problem, it was my coil. I will be replacing it some time this week and will be updating with pictures!
