ACDelco 96451064 Manifold Absolute Pressure Sensor Vacuum Hose

The ACDelco 96451064 is a Manifold Absolute Pressure (MAP) Sensor Vacuum Hose — a genuine OE replacement part designed to maintain the integrity of your engine's MAP sensor signal. This vacuum hose connects the intake manifold to the MAP sensor, allowing the sensor to accurately measure manifold pressure and relay that data to the engine control module (ECM) for precise fuel and ignition timing calculations.

As a GM Original Equipment part, this hose is held to the same engineering standards as the component installed on the vehicle during factory production. A cracked, collapsed, or leaking MAP sensor vacuum hose can cause vacuum leaks that result in rough idle, poor fuel economy, hesitation, and diagnostic trouble codes (DTCs) related to the MAP sensor circuit.

Key Features:

• GM Original Equipment (OE) part — designed, engineered, and tested to GM's rigorous standards
• Direct replacement for the factory MAP sensor vacuum hose — no modification required
• Restores accurate manifold pressure readings for proper fuel trim and ignition timing
• Backed by General Motors for quality and fitment assurance
• Formerly cross-listed under both ACDelco and GM Genuine Parts branding

This part is a reliable, factory-correct solution for restoring proper MAP sensor operation on applicable GM vehicles. Always inspect the MAP sensor vacuum hose during routine maintenance or when diagnosing MAP sensor-related fault codes.
