Product Details and Compatibility

The Standard Ignition AS348 Manifold Absolute Pressure Sensor is engineered to meet the specifications required by Volvo vehicles including the C70, S40, S60, S80, V50, and XC70. This sensor plays a critical role in monitoring the pressure inside the intake manifold, which is essential for the engine control unit (ECU) to calculate air density and adjust fuel delivery accordingly. By maintaining precise pressure readings, the AS348 helps optimize engine efficiency and emissions control.

Common Applications and Problem Resolution

This sensor is used primarily to monitor manifold pressure and support the vehicle’s emission control system. It can help address several engine performance issues such as:

• Erratic engine idling or stalling
• Poor fuel economy due to incorrect air-fuel mixture
• Check engine light triggered by pressure sensor faults
• Reduced engine power or hesitation during acceleration
• Increased emissions from improper combustion

Installation Notes and Tips

When installing the Standard Ignition AS348 sensor, ensure the engine is cool and the ignition is off. Disconnect the battery before removal to prevent electrical shorts. Carefully unplug the old sensor and avoid damaging the wiring harness. Install the new sensor securely and verify all connections are tight. After installation, clear any diagnostic trouble codes and perform a test drive to confirm proper operation.
