Bosch 0261230448 OE Boost Pressure and Temperature Sensor (MAP/IAT)

The Bosch 0261230448 is an Original Equipment (OE) combined boost pressure and intake air temperature sensor, also known as a TMAP sensor. Engineered to Bosch's exacting OE standards, this dual-function sensor delivers precise manifold absolute pressure (MAP) and intake air temperature (IAT) readings to the engine control unit (ECU) in a single compact unit.

Key Features:

• Dual-function design — measures both boost/manifold absolute pressure and intake air temperature simultaneously
• OE-quality construction — built to the same specifications as sensors produced directly for vehicle manufacturers
• High-accuracy pressure sensing — utilizes a silicon membrane resistance bridge for precise pressure measurement
• NTC temperature sensing — employs a Negative Temperature Coefficient resistor for reliable intake air temperature readings
• Chemical-resistant housing — features a special coating that resists harmful chemicals found in the intake manifold environment
• Direct-fit replacement — OE-identical connector and mounting points for a trouble-free installation
• Latest chip technology — continuously refined by Bosch for optimum engine management performance

This sensor enables the ECU to accurately adjust fuel delivery, ignition timing, and boost control based on real-time pressure and temperature data. As a genuine Bosch component, the 0261230448 meets or exceeds original equipment specifications for performance, driveability, fuel economy, and emissions compliance.
