Hey all- I just pulled my stock O2 sensor form my stock '03 xb9r with 2300 miles. I'm going to replace the sensor with a new one (p/n S0130.02A8) but I couldn't find any visible ailments with the one I just removed. How do you know when these little suckers go bad??? Thanks, --ts | ||

Search the Knowledge vault on the words "O2 sensor propane torch" , "AND" (match all keywords). Bunch of stuff on testing O2 sensors. Basically, a propane torch is used to heat the sensor to over 600 degs, and supply oxygen to it. The sensor will put out about 0.8 volts when heated with propane, and should drop down quickly when the flame is removed. | ||

Were you having any issues with the old one and are troubleshooting it? 2300mi's is a pretty short-lived o2 sensor. | ||

its prabably not your o2 sensor itself, check to see if the wire running to it is grounding out on the top of the rear cylinder top... | ||

Thanks all, I appreciate the into. 99x1, the procedure and pics are simple to follow, i will duplicate and advise. Ben_jammin, the bike would lose power when operating at full temp at highway speeds. Dj, the integrity of the wire checked fine. Thanks for all, i'll post the results of the propane torch test tonight. Ciao, --ts | ||

Ok guys, thanks for your help and direction. For what it's worth, I found the knowledge vault information and photos posted by 99x1 to be very accurate and helpful. Basically, I clamped the negative multimeter terminal to the body of the o2 sensor in a vice. I then heated up the o2 sensor tip with a propane torch until cherry red. Placing the positive terminal on the o2 wire lead, the highest reading I could muster was a .546...but that was only once for a brief flash-of-the-screen and I could never validate it with a second reading no matter where I placed/held/stabbed the POS terminal. Throwing out the high, the next highest reading was a .347 and I got readings in this .34x area two other times. It's worthy to note that all readings were taken with the 'inner' or 'light' blue propane flame touching the o2 sensor tip in the same location. Anyway, I'm basically getting less than half of the reading of a new sensor. As such, I'm calling the old one bad and beginning re-assembly. Does this make sense? Am I interpreting correctly? Thanks again for your inputs. Ciao, --ts |
