BD Diesel 1036761 E-PAS Emergency Positive Air Shut-Off for 2017-2023 Duramax L5P

The BD Diesel E-PAS (Electronic Positive Air Shutdown) system provides critical protection against diesel engine runaway—a rare but catastrophic condition where external hydrocarbons are drawn into the engine, causing uncontrolled overspeeding and potential engine destruction. This safety device acts like a fire extinguisher for your diesel engine, protecting your vehicle, your investment, and most importantly, your safety.

How It Works:

The E-PAS system integrates with your truck's existing electronic throttle body in the intake manifold, electronically closing it to cut off air supply during emergency situations. By eliminating the oxygen needed for combustion, the system safely stops the engine before catastrophic failure can occur. Unlike mechanical systems, the E-PAS leverages your factory electronic throttle control for reliable, fast-acting protection.

Key Features:

• Emergency overspeed shutdown protection prevents engine runaway damage
• Electronic throttle body control provides instant air supply cutoff
• Factory plug-in connectors and pre-made wiring harness for clean installation
• Quick installation in approximately 1-1.5 hours—saves 3 hours over mechanical systems
• Automatic reset after shutdown for immediate return to service
• Does not trigger ECM trouble codes or affect normal engine operation
• Tool-free installation except for mounting the activation switch
• Easily removable for truck lease returns without permanent modifications
• 50-state legal—does not require California EO (Executive Order)
