Is there a way to check the voltage of the O2 sensor without having accesses to ECMSpy or Digital Technician? I'm pretty sure that's where the rough running when hot is coming from. Thanks Steve Ford | ||

02 sensor voltage can be measured to ground with engine at operating temperature. http://en.wikipedia.org/wiki/Oxygen_sensor | ||

Yes, but it fluctuates rapidly. A digital VOM will give you enough information to see "yes its working" (rapid V changes) or "nope, its dead" (static V). If you really want to "see" it work, get an air/fuel gauge and watch the pretty lights  I run an a/f on all my turbo cars so I don't go lean at WOT with boost levels more than 3x the factory setting. | ||

The Useless, God love it, took it's annual Summer Dump at 58,000 miles. It finally threw a code this evening and it's the Exhaust O2 sensor (what a surprise). Little does it know I have a spare waiting so nap time will be short lived for the trecherous old pile. In the meantime, I'll ride the X1W. Whoever would have thought the tubers would be Old Reliable? | ||

Good job calling it before confirmation!!  Yep, I've found if you're going to own a Harley it's good to have a back up and sometimes the back up needs a Harley!  | ||

Which sensor? Is that an auto type that can be had at Autozone etc.? Bosch, right? Thanks | ||

The one screwed into the rear header buried beneath everything. I'm going to use a spare stock one and I'm not sure if the sensor is the same as on the old Tube frames. This is from the X1 Files: Bosch 12014 has the correct Weatherpack connector. It is just unplug, unscrew, screw in and plug in. The O2 sensor from a 1993 Chevy pickup will work... it also plugs right in, the wire is about 2 inches longer but doesn't seem to be a problem on an S-3. | ||

A couple of hours later and the old heap is back on the road and it sure is nice to lose the surging, bucking and farting that's been going on for way too long. It was odd in that the snout was mostly white instead of black like you normally see with a used sensor. The original made it 58,435 miles and the replacement was an NTK 21002 from AutoZone. NTK as in NGK spark plugs. I think that the part number from the X1Files listed above is for the tube frame bikes which is why I had to run out to AutoZone. | ||

IIRC 30K is about it for them. I replaced my original about 20K ago with the Bosch 12014. I've got a Denso 234-1001 in the garage right now waiting to go in. We just started carrying the NTK line where I work, I'll have to check out that 21002. |
