Senator pushes EPA for quick fix to DEF sensor



Senator Marsha Blackburn, R-Tenn., Is asking the Environmental Protection Agency to approve a software solution that will address a shortage of diesel exhaust fluid sensors.

Blackburn sent a letter on Monday October 18 to EPA administrator Michael S. Regan requesting relief for truckers and motor carriers. Chip shortages and supply chain disruptions have made it difficult for truckers to repair their trucks when the DEF component fails.

“I am writing to express the unavailability of replacement DEF sensors for American truckers,” Blackburn wrote. “As you know, the global shortage of microchips is causing extreme hardship for trucking companies. I urge the Environmental Protection Agency to redouble their efforts to facilitate and approve a software problem solution to alleviate this dire situation. Hurry up. “

Blackburn said manufacturers of DEF sensors are working on software solutions and asked the EPA to speed up the approval process.

“If approved, it would ease a huge burden on truckers and motor carriers across the country,” she wrote.

Blackburn also drew attention to when DEF sensors “downgrade” trucks and force them to slow down to 5 mph.

“Whether it’s downgrading due to malfunction or really high DEF levels, no affected truck can be used to transport cargo,” she wrote. “In addition, the downgrading of a loaded road utility vehicle creates an extremely dangerous situation for the driver, the drivers who share the road with the trucks, the shipper and / or the consignee, and the insurance provider responsible for load.”

Blackburn requested a response from the EPA within 30 days.

The Owner-Operator Independent Drivers Association contacted its members in Tennessee on October 19 to advise them of Blackburn’s efforts.

“Sen. Blackburn specifically pointed out what we heard from members of OOIDA, namely that downgrading a truck due to DEF sensor failure creates a safety hazard for drivers,” wrote the ‘Association. LL
