How many miles should I expect to get out of the ET sensor? Mine went out at 20k. Anybody had to replace this one multiple times? Thought that I saw a thread stating that they weren't too reliable somewhere.

 

Mine went out around 45-50K, and I´m at 90K now. Thinking about putting one in the saddlebags. I was less than 100 miles from home last time, but.......................

 

Some 7000, some 50,000 plus, I'm at 53,000. Unfortunatly anything electrical is unpredicatable, the ET is just the main sensor failure and gets brought up alot.

 

Right on...Replaced one not to long ago with 22k,But got a RK in thr shop right now with 66k,and no issues.

 

I've got 65,000 miles or so.....temperature sensor never replaced. Never know about electronic stuff.....that stuff usually goes without any warning.

When it comes to the Magnetti-Marrelli.....I would say the Idle speed controller is probably more prone for failure. This item gets worked alot....therefore it will wear out.

Problem is with this system.....not many people are very knowledgeable about it. People often replace wrong parts on this system. They assume or guess it is a certain part. In fact, there is not much information about this system....probably why so many dump this entire system.

I've seen too many people replace the Engine temperature sensor.....often their problem was something else. People start replacing this first everytime something goes wrong....

 

Thanks for the replies. Maybe I won't have to revisit this problem for quite a while

 

I would think that the Temp sensor would be an obvious problem when the engine acts up only after it warms up. The sensor on my 96 Ultra lasted around 35K when I replaced it on the summer of 08
