Intake Manifold Absolute Pressure

WARNING: This page is about a different car, the 1992 Mercedes-Benz 400E. However, it is still accessible from the selected car via links, so may be relevant.

Intake manifold pressure conditions are detected by the pressure sensor in EZL/AKR ignition control unit. EZL/AKR ignition control unit pressure sensor conditions are transmitted to LH control unit through Controller Area Network (CAN). Intake manifold pressure conditions are required by LH control unit during engine cranking up to 600 RPM, and for fixed operating mode for entire engine speed range if hot-wire air mass sensor fails.
