Locker Position Sensor Potting - DANA 44

[alphawolff]

The question is if the later style sensor appears to have a similar failure rate

i havent seen many fail recently so id say thats a fact

That's why god invented zipties

not true, Maurus Logan holds the patent.

Flashing just means the module is reading the signal as “in-transit” and is not reporting a failure.

Replace the sensor with one from the 5-pack kit.

Reporting back. Got the 5 sensors shipped to India. They were labelled 1,2,3,4,5
The No 1 worked and I dont have the light anymore.
Thank you for all the help.

God invented them. Logan stole the idea and patented it. The patent has long since expired…as has Logan.

Why don’t they make a sensor that mounts outside?

A quick story about my own sensor failure.

I saw my rear sensor start failing while towing. After rebooting / cooling down / waiting it out for a while the warning on the dash went away and we continued our trip.

2 months later we had another big trip planned. I potted both front and rear sensors in preparation. When i pulled them the rear was completely full of oil. The front had a small amount of oil but wasn't as bad.

We finished that major 5000 mile road trip with no sensor failure. I thought i was in the clear.

Fast forward about 4 months later, and on another adventure, the dash light came back on again and has been on ever since.

I may have screwed up the potting process somehow or my sensor may have already been damaged before i got around to potting it, but in my case i definitely had sensor failure after potting.

I still have to open things up and see what it looks like but i'll probably try potting the new sensor before putting it in just to be safe.

The damage was likely done before potting. Degraded performance from the caps being exposed to the oil. You didn’t screw anything up. Mileage doesn’t matter, nor does time, or temp. Once the oil hits the PCB, the damage has already begun. Best practice to help it survive is to clean it out with CRC QD cleaner. That would get any oil trapped in the PCB. Potting it without cleaning will trap any oil in there that was there before.

If they’re potted clean or new, then you’re still susceptible to regular MTBF times or regular old failures. It only protects from outside influence of the oil and environment.

For those of us at the back of the class thanks for the simple definition of mean time between failures,

Forgive me if this was covered but I’m too lazy to sift through 75 pages

What’s the difference between doing this and just running the bypass cable?
