I'm working on my friends 89 camaro iroc.
we just replaced the o2 sensor and it's comeing up with a code 13.
witch is an open o2 sensor circuit.
any ideas on what might be causing it to set the code?
it's a new bosch.
I was told that they were having a problem with the bosch o2 sensors.
Thanks for any help.

did you clear the ecms memory of the old code after the new install.

yep sure did the last code before I reset the ecm was a 44 or a 45 rich or lean condition too long.
so I replaced the o2 because we had no idea when it was changed last.
reset the ecm after and got the code 13

thanks,

bad connection or bad o2

You might have a bad wire to the ECM. For this you will need to hook up a DVOM to the O2 sensor wire to see if you are getting feedback. If you are, tap further up the line past the connector. If not, you have a bad connector. If so, you might want to tap it a tthe ECM itself to see if it si broken somewhere you cannot see.
