o2 sensor oddity
03 accord LX coupe, V6 250,000 miles
Check engine light on for quite a while. Just replaced the upstream o2 sensors hoping this will fix problem. Check ODB and the readings for the new sensors appear to be in range. But the ODB program is reporting that both the bank 1 and 2, second sensors are reporting no electrical contact with the sensors. This makes me think that maybe there's a wiring problem more than problems with the sensors themselves.
What would cause this and where is a good place to start looking for the problem. Or is it possible that both downstream sensors are bad and causing the no voltage error code.
How hard is it to change these sensors? Upstreams were easy other than spending more time than needed trying to get the connectors to release. I think those things were designed by the devil.
