Bosch 31432308 Boost Pressure Sensor MAP Sensor for Turbocharged Engines

The Bosch 31432308 is a direct-fit OEM-quality boost pressure sensor, also known as a Manifold Absolute Pressure (MAP) sensor, designed for use in turbocharged internal combustion engines. It monitors intake manifold pressure in the air path between the turbocharger and the engine, delivering precise absolute pressure readings to the engine control unit (ECU).

The ECU uses this data to calculate the correct fuel delivery, optimize ignition timing, manage boost pressure control, and reduce raw emissions. A failed or degraded boost pressure sensor can result in poor engine performance, incorrect air-fuel mixtures, excessive fuel consumption, or fault codes related to boost pressure or turbocharger operation.

Key Features:

• OEM-grade boost pressure (MAP) sensor engineered to Bosch factory specifications
• Measures absolute intake manifold pressure for precise ECU fuel and boost management
• Supports accurate control of exhaust gas recirculation (EGR) and turbocharger boost systems
• Manufactured by Bosch, a globally recognized leader in automotive sensor technology with decades of OE supply experience
• Direct replacement — restores factory sensor performance and eliminates boost-related fault codes
• Built for durability with resistance to heat, vibration, and automotive fluids

Bosch is one of the world's largest original equipment suppliers of automotive sensors, providing components to vehicle manufacturers and the professional aftermarket. The Bosch 31432308 boost pressure sensor is a reliable, precise replacement that helps maintain proper engine management and turbocharger system performance.
