I got some codes

[Xhondaguy]

OK so i have been having an intermittent ses light coming on for about a month now and i finally caught it in time to have it read. I thought it would be just one code but it came up with 5, they are P101 P107 P304 P121 and P401, i have brand new plugs and wires and the car seems like its running good. Oh and I just put a new MAF sensor on, my question is do you guys have any idea what would be tripping all of these codes cause the car is running perfect? And by the way I need to pass emissions in 3 weeks so this is great timing:th_shakinghead1:

Those don't look like complete codes. They're usually a letter (most often P), followed by four numbers. You only have three numbers. I'm going to assume you mistakenly omitted the first number which is sometimes zero.

P0101 - Mass air flow circuit, range or performance problem
P0107 - Manifold absolute pressure sensor circuit, low input
P0304 - Cylinder no. 4 misfire detected
P0121 - Throttle position sensor circuit, range or performance problem
P0401 - Exhaust gas recirculation, insufficient flow detected (could be related to the MAP sensor error)

That's most of the sensors your engine has. If they were all faulty, I don't see how it's running. You need to get them cleared and see what comes back. They take a while to clear themselves if the error goes away. Otherwise I think you have some chafed wires in the PCM harness or something.

Did you start the car with something unplugged?..... a bad sensor can cause codes in various places, what year is you car??

ya sorry i left out the O but you got the point anyways, and no i havnt started the car with anything unplugged, my dad was telling me that my cone filter i have on could be messing up the sesors if its oiled to much, he also said that some of those codes could have already been there before the ses light was tripped from when i had to replace my MAF. So i guess i will clear the codes and scan it again after work
