Detailed Product Description

The Standard Ignition AS443 is a Manifold Absolute Pressure (MAP) sensor that provides real-time data on the pressure inside the intake manifold. This information is vital for the engine control unit (ECU) to calculate air density and adjust fuel injection accordingly. Designed specifically for use in Land Rover LR2 and Volvo models including S80, V70, XC60, XC70, and XC90, this sensor ensures compatibility and reliable performance. The AS443 sensor helps maintain optimal engine operation, contributing to smoother acceleration, better fuel economy, and reduced emissions.

Common Applications and Issues Addressed

• Helps resolve rough idling and engine stalling caused by incorrect manifold pressure readings
• Improves fuel efficiency by providing accurate air pressure data to the ECU
• Reduces engine hesitation and poor acceleration issues
• Assists in maintaining proper emission levels for compliance with environmental standards
• Prevents check engine light triggers related to faulty MAP sensor signals

Installation Notes and Tips

• Ensure the engine is cool before installation to avoid injury
• Disconnect the battery to prevent electrical shorts during replacement
• Locate the existing MAP sensor on the intake manifold and carefully unplug the electrical connector
• Remove mounting screws and replace with the Standard Ignition AS443 sensor
• Reconnect the electrical connector and battery, then clear any diagnostic trouble codes
