Emergency Vehicle Fleet Repair Done Right: Wheel Speed Sensors on a 2023 Ram ProMaster at Leon’s PROFIX in Norman, OK


Philip Defatta • August 6, 2026

At Leon’s PROFIX Auto Repair in Norman, we’re proud to keep essential emergency vehicles running safely and reliably for our local communities.

We recently completed service on a 2023 Ram ProMaster 2500 ambulance for Murray County EMS.  The unit arrived with an intermittent highway issue: the traction control light would flash, the vehicle would lose power, jerk sharply, and make a distinct skirt-like sound.


At Leon’s PROFIX, emergency vehicle and fleet repair is a big part of what we do. We service a wide range of ambulances and commercial fleet vehicles, stocking common ambulance-specific parts so we can get critical vehicles back in service faster. Whether it’s intermittent electrical issues, ABS system problems, or routine maintenance, our team understands the importance of quick turnaround and rock-solid reliability when lives depend on the vehicle.

Ambulances and commercial vehicles need the kind of fast, accurate resolution we offer at Leon's PROFIX Auto Repair.

Diagnosis & Repair at Leon’s PROFIX Auto Repair


At Leon’s PROFIX, we don’t guess — we test. Accurate diagnosis saves fleet operators time and money by avoiding unnecessary parts replacements and getting vehicles back in service quickly and reliably.


Our skilled technicians performed a thorough test drive and diagnostic process to replicate the intermittent issue. We confirmed the root cause was faulty ABS wheel speed sensors and replaced all four.  Parts were promptly received through our supplier network and the ambulance is now repaired and back in service, protecting Murray County.


This repair is a great example of the kind of work we do every day at Leon’s PROFIX on N. Porter Avenue and at PROFIX Auto Repair on Rambling Oaks Drive in Norman, OK.
