Error code Questions

Ok guys, I have a check engine light on, I took my lude to the local auto shop and had them read the codes. To my dismay there were three that came up: P0420, P0133 and P1259. They printed off for me the possible reasons why I would be getting those codes. Has anybody had any experience with these codes before? Is there a way to diagnose the codes without spending $100 to take her to a dealer to have them diagnose them?

Re: Error code Questions

P0420 is a cat code. Make sure you don't have an exhaust leak cause that could cause a p0420. More times then none p0420 usually means replacing the cat.
P0133 is ho2s1. Not sure but I think that pertains to the heater circuit. Can someone else chime in on this?? If I'm correct then that sensor is junk and needs replacing.
P1259 seems to be related to vtec. Can't really help you on that cause I don't have enough exp in the area as of now. Hopefully someone chimes in so I can lean something new as well!!
