I have an 09 Laramie 2wd that is giving me a rear assist error on my dash, I had cured it with wiggeling them around but now even after separating the plug and spraying wd 40 in them they still are not working. Can they be checked to see which one is defective< maybe with an OHM meter and where is the cheapest place to replace them.

rock auto sells aftermarket ones. I haven't tried the dorman ones, but I probably will next time as the mopar ones are pricey.

I heard the aftermarket ones don't work correctly. Just what I was told. My uncle works for a chain of autopart international stores here in ny, and he's heard nothing but bad reviews.

I've tried a few that didn't work, which is why I've gone to mopar. I just haven't tried the dorman ones and they might have finally made one that works. I replace so many that I really want one of the aftermarket ones to finally work as the mopar ones don't seem to last me very long either. I replace 1 or 2 a year just to shut the warning off.

Mine are about 9 years old so no complaints, mainly wondering if there were a way to check them

Check to make sure one of your knucklehead friends didn't put a little piece of black tape on one to screw with you..... Speaking from experience of course....

That's weird. My truck is 3 years old and still on original sensors.

May just be all the snow rain and mud I drive through regularly. They usually stop working once the snow starts flying and I replace whichever ones are cooked in the spring. The connectors aren't waterproof and that seems to be that moisture in the connector is what's causing all my issues. Maybe they'll make them with a sealed connector or a sealed lead so the plug is in a dryer location eventually, but it's been a enough years now without change so it seems unlikely.

I live in upstate ny, buffalo. We have rough winters. But, I do have the truck undercoated with sprayfilm every fall to prevent rust. I wonder if it protects them also?

Maybe I'll fluid film the plugs this year and see if that helps.
