Dodge ram wheel speed sensor problems

Hey everyone - I have a 2014 1500 5.7 sport with 60k miles that started showing service trailer brake, service abs, service electronic brake messages the other day. Abs and trac lights on dash. Cruise, 4wd, trac, abs don’t work. Took it to dealer for a scan, they said there are about 8 or so codes thrown because of a bad rear left wheel speed sensor. Bought a new one, replaced it. Old one didn’t look damaged, wires appear to be fine. Started truck and got all the same messages and warning lights. My scanners showing codes C0037-1D left rear wheel speed sensor circuit out of range and U1412-00 implausible vehicle speed signal received. When I try to clear the abs codes my parking brake light flashes and truck beeps, but code won’t clear. I’m a bit stumped...anyone else experience this issue? Trucks stock. Battery disconnect and checking that fuses are properly seated didn’t help. Could it be a bad abs module?

Had this problem on 2 different rams, both times indicated rear right sensor (non communication) replaced wheel sensor ended up being bad corroded wiring between driver fender to back sensor. ran new wires fixed.
need to do a continuity test on wires to wheel sensors to connector under drivers door connector(lay on ground look up will see connector

Hey thanks for the advice. Maybe the Winnipeg road salt here go the best of that wire. Did you just cut the run near the connectors and replace it? Where abouts is the connector at the front? Familiar with where the rear one is after replacing that left rear wheel speed sensor.

That connector looks way bigger than the one near the wheel speed sensors but I guess they might all converge to go through the firewall? 2 wires for each wheel, so 8 pin connector?

so i worked on 2004 and 2007 and my plug was slightly diffferent had to take plug apart and run 2 new wires along harness, but testing the right wires to make sure theres a problem with it is best. have to check ohms while wheel sensor is turning possibly at the plug under drivers door towards fender

I went under there to check things out today. Only thing I could find near the driver door/mud flap was a 16 or so pin connector. Is that the one?

again mine were 04 and 07 connector was located between inner fender around drivers foot. so i would say that is likely it but you need unclip the connector make sure it is clean and not corroded. you can do a continuity test from the senor to the connector to try to find the right or put a wire tracer on the speed sensor to try to locate it. i would search youtube to solve bad auto wire there are videos showing several techniques.

When i fist had this problem on my 07 my dealer changed my abs controller under the hood at a cost of 1900 lights went out for a year but came back on and ended up being bad wires.
MY 04 it was that plug that had multiple bad wires (chafed from winter ice) caught in under the wheel well and fender.

Man, it would be nice if my truck looked that clean and rust free underneath...ahhh California...:smiley_thumbs_up:

I ran over a couple of clumps of snow 2 weeks ago, they had fallen off of a vehicle that was coming out of the mountains & it has rained quite a bit in the last month.
I bet my under carriage is not very clean right now.
I would like to find a car wash that has the under body spray

My Ram is now 4 years old & has not seen roads with snow on them & it only rains in November - February/March

There’s a serious defect in these trucks around these years. Mine is a 2014. You can see from the pics that this wrapped up wire run is tucked away on top of a frame rail away from the elements and has not been touched or hit by anything since it left the factory. They overtighten the zip ties and over time it crushes the cables. Pretty scary as these wires control abs and traction control and can go out at any time...my truck has 81,000 km, that’s only 50,000 miles!!

Hi Rocket61, i have a 2017, and i have exact same problem than yours, i change my WSS, and the code come again, i see the bunch of cable, you repair the wire and the code is gone? everything is fine after? i will check that tomorrow. please let me know

Hi @CmaElectrique - If you work with your dealer to address this, we suggest contacting Canadian Customer Care to have this documented. You may find their contact information by clicking on the following link and scrolling down to the "Canada" tab: Contacts | FCA Group.
