Walker 225-1378 Manifold Absolute Pressure Sensor

Walker Sensor Only MAP Sensor for Volvo

Walker Products Part Number 225-1378 is a Manifold Absolute Pressure (MAP) sensor built as an OE replacement for Volvo applications. It measures intake manifold pressure and sends that signal to the ECM so the engine can calculate load, fuel delivery, and ignition timing with the correct input.

The Sensor Only line from Walker focuses on direct-fit replacement sensors engineered for electrical output, pressure range, and connector fit. For Volvo S60, S90, V60, XC60, and XC90 applications, this MAP sensor supports accurate engine management and consistent drivability.

Installation Notes and Tips

Verify connector shape, terminal count, and port configuration before installation. This sensor uses a plug-in, 1-connector design with a rectangular female connector and 3 male terminals, so matching the original electrical interface is important for proper operation. Confirm the vehicle application by year and model before replacement.
