Walker Products 225-1121 manifold absolute pressure sensor for the 2003-2007 Mazda 6 V6 3.0L and other vehicles reads intake manifold pressure and sends it to the engine computer. It does this through a changing voltage, and the computer uses the reading with other inputs to calculate how much fuel to deliver.
- Three blade terminals in a single rectangular connector
- Single port
- Built to withstand high engine bay temperatures, vibration and intake air contaminants
- Tested for accuracy, responsiveness and long-term reliability
Quick facts
