I know....another 900 question!!
Over the last two rides I noticed my check engine light barely flickering, then it would flash a code (5 flashes) and go away, then it started flashing constantly (5 flashes) but go away when the machine was below 3000 rpm. The service manual stated if the probe was out of the parameters and over 3000 RPM for 2 or more minutes the light would flash.
Ok, great. bought a new probe installed it and now it flashes the code (5 flashes) constantly even at idle. WTF? So, I ride 80 miles like this and the machine runs flawless. I go to the dealer on the way home and they are no help at all. The mechanic says "it is the probe".....really, no shiz!! Apparently there is no way to purge the error code memory....gotta find the problem.
So now I trouble shoot. I look at the connector plug closely and the wire is completely broken inside the insulation...fix that with a new connector. decide to do a continuity check on all the probe wires from the ECU (pain in the arse) but good news both wires have continuity. decide to run the sled for kicks without the probe plugged in......yup you guessed it 5 flashes at idle!
OK, maybe it has to do with the MAF sensor since they run in parallel. Checked those wires from the ecu to the sensor...wires good. MAF sensor also has good continuity. Unplugged MAF and it flashed 5 flashes then 3 (MAF code), plug both back in and still 5 flashes. I have the dealer getting me a new exhaust sensor, but the odds of the sensor being bad is slim to none. Any ideas?? Machine runs great with the light flashing. I am stumped any help would be great. Please no smart arse comments.
