Hi so i own a 1997 Honda Civic LX. ive had quite a few problems with it since i bought it in novembor. ive had to put in a new distributor system, battery, serpentine belt, alternator belt, AC belt, and i had a co2 cleaning in my 2nd cylinder. now my engine light is on again and its giving me the codes...

P0420-Catalyst system efficiency below threshold-Bank1
P0430-Front bank catalyst system efficiency below threshold-Bank2
P0750-Problem in Hydraulic Control System of shift solenoid Valve A circuit

So with that being said i am not the greatest with cars, all the other problems i just had my mechanic fix but money is tight. i was wondering if someone could help me out with what these codes actually mean, and how i could fix them. also how much it would cost to fix all this. i appreciate any help and thank you in advanced :D.

 

p0420 and p0430 have to do with your cat. p0420 is a bad cat and p0430 is o2 sensor. p0750 is beyond me do a google search on that one.

 

this might help http://www.p0420.com/ same things for P0430 bad cat or bad downstream O2 sensor

P0750 check these
- Low transmission fluid level
- Dirty transmission fluid
- Faulty shift solenoid A valve
- Shift solenoid A valve harness or connectors
- Shift solenoid A valve circuit is open or shorted

 

I bought from a friend a Honda Civic 2000. She did not have the radio code and has been 1 yrs without listening to music and is driving me crazy. I found some stickers inside de compartment glove but you can see them only using a mirror. Needless to say that you need to be a contorsionist to be able to read them because you see them in reverse. the VIN# 2HGEJ6611YH555618. Please help!!! I'll be in your debt forever!!

 

on your radio. hold down the 1and 6 buttons and press the power.
it should give you an 8 digit code. what is that code?

 

All you need is the S/N that is on the radio and call the dealer. When you get the code, take a marker or white out and write it inside the glove box. Every time you disconnect the battery , the radio goes into security mode.

 

Way to jack a thread!
