Holstein 2MAP0454 Manifold Absolute Pressure (MAP) Sensor

The Holstein 2MAP0454 Manifold Absolute Pressure (MAP) Sensor is a direct OE replacement sensor engineered to restore precise engine management performance. Designed for fuel-injected engines, this MAP sensor delivers instantaneous intake manifold pressure data to the vehicle's electronic control unit (ECU), enabling accurate fuel delivery calculations and optimized ignition timing.

How It Works:

The MAP sensor continuously monitors intake manifold pressure and feeds that data to the ECU. The ECU uses this information to calculate air density and engine air mass flow rate, determining the correct fuel metering for optimal combustion and influencing ignition advance or retard.

Key Features:

• Direct OE replacement — exact fit, form, and function for a hassle-free installation
• Manufactured to exacting standards using premium, heat-resistant materials for long-term durability
• Exact OE-matching connector and mounting points for plug-and-play installation
• Restores factory-level fuel economy and engine performance
• Sealed anti-static protective packaging protects the sensor during shipping
• Backed by Holstein's 3-year / 36,000-mile warranty

A failing MAP sensor can disrupt the air-fuel mixture and ignition timing, potentially triggering a check engine light and diagnostic trouble codes (DTCs). Replacing it with the Holstein 2MAP0454 returns your engine management system to factory specification.
