Product description

The intake temperature manifold absolute pressure sensor performs "dual duty" as a barometric sensor as long as the key is turned on. When the key is on (before the engine starts), the vacuum in the engine does not act on the intake manifold absolute pressure transmitter, so the signal it sends to the ECM becomes a pressure reading that helps determine air density. When the engine starts, the pressure in the intake manifold decreases, creating a vacuum that acts on the intake manifold absolute pressure sensor. Specializing in the manufacture of absolute pressure sensor intake manifold, common rail pressure transmitter.
