Engine / Intake Pressure Sensor
OEM Part Numbers: 89421-71030, 89421-71020
This high-quality pressure sensor is designed for selected Mazda models. The sensor measures intake manifold or engine pressure and sends accurate signals to the engine control unit (ECU). These signals are critical for optimizing fuel injection, ignition timing, and turbo boost management for smooth engine performance and fuel efficiency.
A faulty pressure sensor may cause:
-
Engine misfire or rough idle
-
Poor fuel economy
-
Loss of power or turbo issues

Replacing a defective sensor restores proper engine operation and maintains optimal fuel efficiency and performance.
