Reliable Manifold Absolute Pressure Sensor for Lexus and Toyota Vehicles

The Standard Ignition AS308 Manifold Absolute Pressure Sensor is designed to provide accurate engine load data for optimal performance. Compatible with select Lexus and Toyota models, this sensor helps maintain efficient fuel management and emission control.

• Direct replacement for OEM manifold absolute pressure sensor
• Compatible with Lexus 4Runner, GX470, Land Cruiser, LX470, and Toyota Sequoia, Tacoma, Tundra
• Ensures precise measurement of intake manifold pressure
• Supports engine control unit (ECU) for improved fuel efficiency
• Durable construction for consistent performance under various conditions

Product Details and Compatibility

The Standard Ignition AS308 is engineered to meet the specifications required by Lexus and Toyota vehicles including the 4Runner, GX470, Land Cruiser, LX470, Sequoia, Tacoma, and Tundra models. This manifold absolute pressure sensor monitors the pressure inside the intake manifold, providing critical data to the engine control unit (ECU). Accurate pressure readings allow the ECU to adjust fuel injection and ignition timing, which is essential for maintaining engine efficiency and reducing emissions.

Common Applications and Issues Addressed

• Helps resolve rough idling and engine stalling caused by incorrect manifold pressure readings
• Improves fuel economy by providing accurate load data to the ECU
• Reduces engine hesitation and poor acceleration issues
• Assists in maintaining proper emission levels to pass inspections
• Prevents check engine light triggers related to manifold pressure sensor faults

Installation Notes and Tips

Installation of the AS308 sensor requires basic mechanical skills and standard hand tools. Before installation, ensure the engine is cool and disconnect the battery to avoid electrical shorts. Remove the old sensor carefully to prevent damage to the intake manifold or wiring harness. After installing the new sensor, clear any diagnostic trouble codes (DTCs) using an OBD-II scanner to reset the ECU. Verify proper sensor operation by checking for smooth engine performance and absence of warning lights.
