Standard Ignition AS631 Manifold Differential Pressure Sensor

Overview of Standard Ignition Manifold Differential Pressure Sensor AS631

The Standard Ignition Manifold Differential Pressure Sensor AS631 is designed specifically for BMW 760Li models. This sensor plays a critical role in monitoring the pressure difference within the intake manifold to ensure optimal engine performance and emission control.

• Compatible with BMW 760Li vehicles
• Black finish for durability and corrosion resistance
• Female oval plug-in connector with one connector
• Three male blade terminals for secure electrical connection
• Includes one vacuum port for accurate pressure measurement
• No hardware, mounting brackets, O-rings, or wiring harness included

Detailed Product Description

The AS631 manifold differential pressure sensor from Standard Ignition is engineered to provide precise pressure readings within the intake manifold of BMW 760Li vehicles. Featuring a black finish, this sensor is built to withstand the demanding environment under the hood. It includes a single female oval plug-in connector designed for easy and reliable connection, with three male blade terminals ensuring stable electrical contact. The sensor also incorporates one vacuum port to accurately detect pressure differentials, which is essential for proper engine management and emission control systems.

Function and Common Applications

This manifold differential pressure sensor is used to monitor pressure differences in the intake manifold, which helps the engine control unit (ECU) optimize fuel delivery and emissions. It is commonly used to address issues such as:

• Erratic engine idling or stalling
• Check engine light triggered by pressure sensor faults
• Poor fuel economy due to incorrect air-fuel mixture
• Reduced engine performance or hesitation
• Failed emissions tests related to sensor malfunction

Installation Notes and Tips

Installation of the Standard Ignition AS631 sensor requires careful handling to avoid damage to the connector and terminals. Ensure the female oval plug-in connector is securely attached to the corresponding male connector on the vehicle wiring harness. Since no mounting brackets or hardware are included, reuse the original mounting components or source compatible hardware. Verify the vacuum port is properly connected to the intake manifold vacuum line to maintain accurate pressure readings.

Quality Assurance and Warranty

Standard Ignition parts are manufactured to meet or exceed OEM specifications for fit, form, and function. The AS631 manifold differential pressure sensor undergoes rigorous quality control to ensure reliable performance in BMW 760Li vehicles. While specific warranty details may vary, Standard Ignition typically offers a limited warranty covering defects in material and workmanship.
