redjohnuk Posted September 3, 2017 Share Posted September 3, 2017 Hi allDoes anyone know how to test a Lambda sensor to see if its working correctly. I run a 1.6 Mega Grad on a Supersport EU3 ECU and its been giving me a few running issues as in revs sticking ranging between 800 and 1200 {up and down}. Changed the TPS, the ICV and both water rail temperature senders......and done various resets.Anyone got any ideas?ThanksJohn Link to comment Share on other sites More sharing options...

redjohnuk Posted September 3, 2017 Author Share Posted September 3, 2017 Done that...seems that the readings im getting are within the normal expacted of .2V to .9v and very quick changes. Also makes a difference the running when disconnected after the engine started....so its not that ( i think ) I have discovered that with the ICV sealed off the engine starts but needs throttle to keep it going until warmed then it runs fairly smoothly. Unsealing the ICV the revs pick up and stay up....Changed the ICV but no different. Confused....you bet Link to comment Share on other sites More sharing options...
