Yamaha motorcycle 02 warrior ecu diagnostic codes
It's either a bad connection or a bad sensor. The sensors are connected to the ABS unit.

#YAMAHA MOTORCYCLE 02 WARRIOR ECU DIAGNOSTIC CODES HOW TO#
But I've an idea why (a failing seal) and know how to fix it. And now that I've finally got the V7C running really, really well, the clutch is slipping again. In the next perfect world, any problems should be easily identified & easily fixed. In a perfect world, it should all work right straight out of the box, forever. I didn't find it until I determined to test each sensor - and the TPS happened to be one of the early ones I got to (and learned how to test). There was never any error on this logged in the ECU. The problem with the TPS (a simple potentiometer - so when the throttle is operated, the effect should be linear) seems the be that a flat spot had worn there and at about 3,500 - 4,000 rpm the effect was no longer linear. No dealer, or anyone else for that matter, had much of a clue. I had similar on the V7C (different ECU, mind) - dead spot at around 3,500-4,000 rpm, first started at about 40,000km, and persisted until I swapped out the TPS at 170,000km. The dead spot at 4,000rpm may be connected, or may be another thing altogether. The dealer should now have something to work with. One or other (or both) those speed sensors are playing up, or their handshake to the ECU is. It seems to me, operating from a position of abysmal ignorance & stabbing in the dark, that those error codes point you in a direction. Yes, it should have been sorted at the dealer, but much depends on the skill set & accumulated experience available there to diagnose problems. A flat spot the size of Nebraska ! The dealer was of little to no help. Occasionally it would stall while warming up ,just as it went closed loop.

I don’t dought the benefit of custom mapping, its just not in my wheelhouse this moment. Sooo until get a cash windfall or easier access to a capable computer technician I’m sticking with what has worked OK so far. Oil consumption is minimal, plugs look good, no pinging or other signs of poor running & head temps are pretty even. As I was informed this is a band aid approach. & the drivability issue should be the Mfg’s responsibility.Īgainst the opinion of many here & on other websites I tried a pair of O2 sensor signal modifiers, for which I was severely castigated!Ī huge improvement was noticed almost immediately. I didn’t feel an extra outlay of approximately $500 was prudent as it had under 1k Mi. Many suggested a new map & they are very likely correct.
