Walker Products 225-1146 manifold absolute pressure sensor for the 1995-1999 Subaru Legacy H4 2.2L, the 1996-1999 Legacy H4 2.5L and other vehicles measures intake manifold pressure and sends it to the engine computer. Walker builds it as an OE replacement to OE specifications for electrical output, pressure range and connector fit.
- Reads manifold pressure as a changing voltage signal
- Lets the ECM calculate engine load and adjust fuel injection and ignition timing
- Built to withstand high engine bay temperatures, vibration and intake air contaminants
- Tested for accuracy, responsiveness and long-term reliability
- One oval connector with three blade terminals
Quick facts
- Part: Walker Products 225-1146 manifold absolute pressure sensor
- Fits: 1995-1999 Subaru Legacy H4 2.2L, the 1996-1999 Legacy H4 2.5L and other vehicles
- Condition: New
A worn sensor can show up as a check engine light, poor drivability or a change in fuel economy. Before you replace it, rule out a vacuum leak, damaged wiring and a loose connector, since the same signs can start in any of them.

Frequently Asked Questions
Does the Walker Products 225-1146 fit the 1998 Subaru Impreza H4 2.5L?
Yes. Walker Products 225-1146 fits the 1998 Subaru Impreza H4 2.5L, and that car takes one sensor.
How many terminals does this manifold absolute pressure sensor connector have?
Walker Products 225-1146 has one oval female connector with three male blade terminals.
How does this sensor tell the ECM the manifold pressure?
It changes its voltage with manifold pressure and sends that signal to the engine control module, which uses it to calculate engine load.
Can a failing manifold absolute pressure sensor turn on the check engine light?
Yes, it can. A check engine light, poor drivability or a change in fuel economy are possible signs, and a shop can scan the codes and test the sensor.
Is Walker Products 225-1146 a replacement for part number 22012AA070?
Yes. 22012AA070 is one of the numbers listed for Walker Products 225-1146, along with 22098AA000 and 158-1347.
