DEF Sensor Issue


A number of our member companies as well as fleets across the country have been reporting problems with the DEF sensors on their trucks. This problem does not appear to be OEM specific.  The company that makes the sensors is Continental Automotive.  This apparently is not a new problem, but Continental’s global supply chain is having critical replacement issues and cannot manufacture them in a timely manner because those sensors contain 2 microchips.


Recently, a waiver was requested by Paccar and Cummins from the EPA and USDOT to allow OEMs to develop a software program that would allow for the bypass of the DEF sensors in their engines to prevent the current engine shutdown scenario.  EPA approved this waiver.  The software is currently being written and anticipated to be available for installation by dealerships sometime in mid-September at the earliest.


We recommend that members that are impacted by this speak to their OEM and make arrangements for the software update as early as it is available.

Too good to be true? Believe it!

If you are interested in having some of your employees get their CDL, but don’t want the financial risk of paying for driver training, this program is for you.

In order to grow the CDL driver pool of novice drivers in Colorado, a joint effort by CMCA, CDOT, and CDLE through the Freight Industry Sector Partnership has resulted in a Federally Registered Colorado CDL Apprenticeship Program with these KEY BENEFITS:

  1. CDL training is funded by WIOA Grants for eligible employees (most employees would qualify)
  2. No cost to Employers
  3. Minimal Employer requirements outside normal safety and follow up training

For more information about this program contact the Program Sponsor, Excel Driver Services at 303-942-8002 and talk to Steve Waymel or Theresa Emery.

    In May 2021, CDOT and Coulson Excavating Company began an asphalt resurfacing project on U.S. Highway 85 near Platteville. Over four miles of northbound and southbound US 85 between Weld County Road 22 and Colorado Highway 66  (Mile Points 246 – 250.5) are being improved.  Click here for more info.
  • The emergency truck ramp on West Vail Pass located near Mile Point 182 will close Monday, Aug. 9, and remain closed for about three months while the ramp is reconstructed.  The next closest emergency ramp on Vail Pass is located at Mile Point 185.5.  This ramp reconstruction is being done as part of the I-70 West Vail Pass Auxiliary Lanes Project.

    Hot Brake Cooling Vail Pass:  The two locations we are pointing drivers to use are the MP 190 interchange ramps or the wide shoulder at MP 184 as a place where they can cool their brakes before proceeding WB.  We have construction signs along I-70 for drivers. Attached is a PDF with our plan for the brake cool down areas.
