o2 sensor fail
anyone have a o2 sensor fail?
First off let me say I have a 10 streetglide. About 3 years ago I put a pc-v on it which has you disconnect the 02 sensors. A week ago I upgraded to a PV and hooked them back up. Bike ran ok but I tried the auto tune option which helped but then it got worse. Ran real rich and had a delay off idle. I checked the codes with the PV and it had a "rear o2 sensor not responding" code. I am guessing that since I left the o2 sensors in but not connected that it might have ruined them.
Well, I ordered a new rear sensor which will be here in 4 days.

not shure watz up with your scooter but ive read alot about 02 sensors and they usually just become lazy,replaceing them every so often also improves gas mileage and in cars saves the cataletic converter...

sensors can be damaged by the use of RTV silicone type sealers.
also damaged by running an over-rich mixture
or wacky fuel additives.
I had one go bad in a 1986 nissan sentra- had dozens of other vehicles with out any o2 sensor problems
