Can somebody help me out with these codes!
 

I have a 2000 Civic EX with 127k. The codes that are giving my problems right now are, P0706, P0430, P0420. Anybody else have experience in working with these codes?

P0420 & P0430 = O2 sensors are probably fouled. Take em out and replace them or try to clean them.

P0706 = Trans Range Sensor...this helps select your gear in an AT. There are several causes for this one - a bad TRS sensor, dirty/bad tranny fluid, fluid valve issues in the transmission.

Hey thanks for the reply. I’m going to change the transmission fluid and filter this coming weekend, also try to do some more research about the O2 sensor. With that, should I worry about the catalytic converter at all?
