Engine codes...

[Drift Style S14]

Hey folks, well my friend got a code reader and i got a chance to check if there were any codes on my ecu. I found two.

P0401
P010

I know the second one the air temp sensor, the other one is I believe something to do with exaust recirculation something. I was wondering if someone could find out or knows what the first one is and what it would take to fix it. As for the second one, thats because i have a K&N rigged on to my intake and the sensor isn't hooked up. Thanks for the help.

i would recommend hooking up the air temp sensor. it just think that its there for a reason, even if you have a k&n the ecu would need to detect the air temp just to get the best mixture.

have you tried checking the code not using a code reader? im looking in the chiltons and it doesnt list the first one. goto www.240sx.org and goto the faq and they tell you a way to check the codes withouth a code reader. then post the codes.
