Walker Products 225-1127 manifold absolute pressure sensor for the 2004-2005 Mazda Miata 4-cylinder 1.8L and other vehicles measures pressure in the intake manifold and reports it to the engine control module as a changing voltage. The module uses that signal with other inputs to calculate engine load and adjust fuel injection and ignition timing.
A failing sensor can show up as a check engine light, a rough idle or poor fuel economy, though other faults produce similar symptoms. If the sensor is the cause, this one replaces it. Before replacing it, look over the connector and wiring for cracks, bent terminals or corrosion with the engine off and cool; a shop can test the signal itself.
This OE replacement sensor is engineered to meet OE specifications for electrical output, pressure range and connector fit. It fits the 2004-2005 Mazda Miata 4-cylinder 1.8L and the 1995-2002 Mazda Millenia V6 2.3L. This listing is one sensor, and both cars take a single sensor.

This part cross-references / interchanges with the following part numbers:
Does the Walker Products 225-1127 sensor fit the 2004-2005 Mazda Miata 4-cylinder 1.8L?
Yes. Walker Products 225-1127 fits the 2004-2005 Mazda Miata 4-cylinder 1.8L, which takes one sensor.
How many terminals does the Walker Products 225-1127 connector have?
Walker Products 225-1127 has one black, oval female connector with three male blade terminals.
Is AS147 the same as this manifold absolute pressure sensor?
Yes, AS147 is one of the numbers this sensor replaces. SU4272 and SU9735 are also on its interchange list.
Can a bad manifold absolute pressure sensor turn on the check engine light?
It can, because its signal feeds the engine load and fuel calculations. Other faults give the same sign, so a shop can test the signal to find the cause.
What signal does this manifold absolute pressure sensor send to the computer?
It sends a voltage that changes with intake manifold pressure. The engine control module reads that voltage to work out engine load.
