Two days ago i put an injen cai on my 05 tsx a/t and today my check engine light came on i was just wondering if anyone else had this problem and what you did about it THANKS.

 

Not on my TSX, I had it happen once on my Si but I think it was bc I didn't disconnect the battery. After I did it went off.

I put a Icebox on my car w/o disconnecting my battery and the light didn't go on.

Check the MAF and tube connections for leaks, if everything is ok then try disconnecting the battery if you haven't already done so.

 

Make sure the temp. sensor is plugged in and the hoses are connected the way they should be. No problems with my injen cai

 

it's probably your IAT sensor which plugs into the injen tube after the TB and before the bat tie down. It may be a bit loose. Here's a trick, take some mega hold hair spray and spray it on the rubber gasket thing on the intake and then put the IAT in, that'll hold the IAT in well but not foul it. Then disconnect and reconnect the battery

 

I had just finished installing the K&N CAI one Sat. morning on my Wife's '04 and I had the same thing happen.

We were on the way to IHOP and the car was fine, but after about 5 mins. of driving it came on. I was a little alarmed but figured I missed plugging in the IAT sensor or something. Checked under the hood and everthing was fine.

So after IHOP it was still on so we went to a local Kragen and I bought an OBD II scanner.

But midway through the trip home it went away. So I didn't bother and returned the scanner. The light hasn't come back on since. That was back in '05. I do remember it was a colder day, 52 degrees, it may have caused it, but who knows.

After typing all this out I realized this isn't a helpful response.

I guess the moral is, check your connections, if it's ok then I guess give your car a chance to "learn" the new intake temp. If that doesn't work, buy a scanner and see what code you get.
