Check Engine Light on
 

Folks, appreciate this forum.

I have a Honda civic LX 2004 sedan, check engine ligh came on, took it to Autozone and they gave me a diagnostic code of P0135.

probable cause printed on their print out for the code for Honda

A/F sensor 1 heater malfunction

open or short circuit condition
poor electric connection
faulty A/f sensor


I called a H dealer and a guy in hte service dept told they dont accept other "shop's" codes. also he says Azone doesnt do it properly, they jsut "guess" and when I aksed him how different that they do, he said we use a computer bla bla... and yes they charge only $120 for the diagnostics.

My question is I got remote engine start installed a few months ago for winter, do you think it has anything to do with that system at all? I got that thing at circuit city and they are gone:rolleyes:..

What Iam looking for is what could I do? All this car stuff is kinda rocket science to me... pls advise

Should I go and try with some other dealer? OR is it usual that car dealers have "sophisticated" equipment and they are deemed better?

ThAnks folks for your time

any ideas anyone folks?

The problem would probably be fixed by replacing the primary O2 sensor; however, there is a possibility that the O2 sensor connector, heater wires, or even the ECU is instead bad. You won't know for sure unless you are able to do the electrical troubleshooting.
