Bosch 038-906-051 E Manifold Absolute Pressure MAP Sensor

The Bosch 038-906-051 E is a high-precision manifold absolute pressure (MAP) sensor designed for turbocharged Audi vehicles. Also known as a thrust sensor or boost pressure sensor, this OEM-quality component monitors air pressure within the intake manifold and turbocharger boost system to provide critical data to the engine control unit (ECU) for optimal fuel injection and engine performance.

Key Features:

• Original equipment quality manufactured by Bosch to OEM specifications
• Measures air pressure within the intake system to very fine tolerances for efficient engine performance
• Special coating provides resistance to harsh chemicals and extreme temperatures inside the intake manifold
• Designed for turbocharged applications to accurately monitor boost pressure
• Plug-and-play design with OE-identical connector ports for trouble-free installation
• Helps maintain proper fuel mixture, driveability, economy, and emissions control

This sensor mounts in the intercooler intake pipe and is engineered to withstand the demanding conditions of turbocharged engines. Common symptoms of a failing MAP sensor include poor fuel economy, engine misfires, rough idling, check engine lights, and limp mode activation.
