Hi all
'96 SE
Last week I changed my front 02 sensors with the appropriate Bosch replacements. I also changed my knock sensor. I reset the ECU and both O2 sensor codes returned. Any ideas? Thanks for any help!

 

Are you sure you replaced the right sensors?

 

I also have my check engine light on for EGR and front Oxygen Sensor on the left cylinder bank. i was wondering how much this part would cost? and any other suggestions to what might be wrong?

 

Oh yeah -- I'm sure I replaced the right sensors. Hard to screw that up. 3-wire O2 sensors -- two whites, one black, no polarity, so doesn't matter how they're wired. Ideas?

 

You HAVE changed the air filter recently?

 

My suggestion is to just drive for about 2 weeks and see if the code goes away. It has done this before to me and also others.

 

I changed the air filter a couple of months ago. I'll check it. So sometimes the codes come back and go away? I can understand why they might not go away immediately, but why would the ECU send a code after reset like this? Unless there's still a problem?

 

had the same problem, damn fuse was blown! i would check the fuse, sounds just like the prob i had. i forget the exact location, its the right bank of the in-car fuse panel... somewhere around the middle. if that helps

 

Thanks zazon, I'll check that tonight...

 

my code left me??! for the 0707
but im still gonna change it, might as well anyway.. also what fuse did u guys mean/
