Detailed Product Description

The Standard Ignition AS454 manifold absolute pressure sensor is engineered to provide precise pressure readings from the intake manifold. This data is essential for the engine control unit (ECU) to adjust fuel injection and ignition timing accurately. Designed to meet OEM specifications, the AS454 sensor supports emission control by helping maintain the correct air-fuel ratio, which is vital for BMW 335d and X5 diesel and gasoline engines. Using the correct sensor ensures that your vehicle’s engine runs efficiently and complies with emission standards.

Common Applications and Issues Addressed

• Helps resolve rough idling and engine stalling caused by incorrect manifold pressure readings
• Reduces poor fuel economy linked to faulty sensor data
• Prevents check engine light triggers related to emission control faults
• Improves engine performance by providing accurate pressure input to the ECU
• Supports emission system functionality to meet regulatory requirements

Installation Notes and Tips

When installing the Standard Ignition AS454 sensor, ensure the engine is cool and the ignition is off. Locate the existing manifold absolute pressure sensor on the intake manifold, disconnect the electrical connector, and remove the mounting screws. Install the new AS454 sensor securely and reconnect the electrical plug. It is recommended to clear any diagnostic trouble codes after installation and verify sensor operation with a scan tool to confirm proper function.
