Aging of sensors

Don Abbondio Posts : 143 Join date : 2014-08-26

Allow me this question:
Are sensors affected by aging?
Do they loose their "accuracy" or "responsiveness" by being used?
I am moslty thinking about the engine temp sensor and (less) about the air temp sensor.

Is it advisable to replace them every, I don't know, 10 years?

You can call me paranoid if you want....

They can, I'm more thinking the phase sensor and wire coming out of it. Seen those wiggle in wind or whatever with bad results.
If the sensor is making contact with some other material is a possible failure.
I would do a service test & compair it to a chart or known reading. That is what software does, make our job easier. So they say.

Well ,the phase sensor does age but due to oil leaking it will be replaced at some point.

I am talking about the other two sensors, especially the engine temp sensor.

Read the manual. There are resistance values for temperature sensors listed. Personally I've not had to replace either the angina temperature sensor or air temperature sensor on any CARC bike due to waning efficiency or inaccuracy but that doesn't mean it can't happen.

Checking is easy. Maybe do it every time you service the bike at 10k km intervals.
On a cold engine, connect GuzziDiag. Look at the temperature sensor readings. The IAT should be close to ambient. The ETS should be within a few degrees of the IAT. If they are wildly different, do something.

Angina temp sensor, Pete? Faulty auto-correct, or deeper heart-health concerns? The former, I hope.

Huh? What?.

Nah? I'm OK Pete. I've had a horrible, aggressive, chest infection for a week that did worry me a bit as the coughing fits did trigger chest pains in the areas I felt pain when they put the stents in. I'm fine though I recon. At least I'm a lot better than my friend Vic, who posted as 'Dracula' on ADV, (He was originally from Romania.) who seven weeks ago felt unwell and is now either dead or on his last breaths in a hospice having a late diagnosis of pancreatic cancer, which had metastasised.

I coached him through an engine swap and clutch replacement on his Stelvio and we had started on a full engine rebuild on his 185,000 mile Stelvio motor. I was really looking forward to his elation when he slotted that in and fired it up but it wasn't to be. His death has hurt me as much, if not more than Steve's.

No, I'm fine. Fucked, but fine! 67 years, 50 of those spent, as my doctor said, indulging in "High living and low thinking." have taken their toll. Would I change anything if I had the chance? Probably. But we don't get that option and I've had a fantastic life! Really. Nobody lives better than me!

If I suddenly keel over and go 'Thud' please support Jude, she'll need it! But right at the moment I'm not anticipating it and think it's a reasonably remote possibility.

Now back to the arduous task of running my Midget Porn Empire from my garage! cheers

The check's been performed. IAT and ETS gave the exact same reading. Doublechecked with a laser thermometer pointing on the engine block.
All good...

Sorry, Pete, I was just chuckling over the inadvertent typo in your post above:

Sometimes I just find things amusing, no offense intended. I'm glad you're doing okay and I'm really sorry about your friend. I feel your pain. I'm still really struggling with losing Steve. I've experienced heartbreaking loss in my life before, but his death has stung more than usual and the Ghetto is a constant reminder of his absence. Be well and try to ignore my weird sense of humor.

Pete

No offence taken Pete, in fact I had a quick glance back and couldn't find the original post to check it!

Yeah, we've all been there with loss. It never gets easier fuck it!
