(888) 312-8812 Login SignupThe Mack Sensor sends the signal a Mack control system relies on to monitor the circuit it serves. When the Mack 21045060 replaces a failed or drifting unit, the control module receives accurate input again. A bad sensor can set a fault code or light a warning even though the system itself is sound. Technicians clear the code with confidence, and the truck goes back out without a repeat dash warning.
