P1129 ACURA Description

The Manifold ??solute Pressure (M??) sensor generates a signal that is proportional to the amount of vacuum in the intake manifold. The signal is sent to the Engine Control Mudule (ECM) and the information is used to control the air/fuel mixture ratio. Faulty M?? sensor can cuase the engine to stall, surge or a rough idle.
