The intake manifold pressure sensor measures the intake manifold vacuum that exists in the intake manifold after the throttle. The measured values of the intake manifold pressure sensor and the intake air temperature sensor are required to calculate the intake air mass. Depending on the injection system, the intake manifold pressure sensor and The MAP sensor, or the manifold absolute pressure sensor, is an essential component of the engine management system in the Honda Accord. Also, a MAP sensor is found in fuel-injected vehicles, and its primary function is to provide information about intake manifold pressure to the Powertrain Control Module (PCM/ECM). What are the symptoms of a bad manifold absolute pressure sensor? The main symptoms of a bad manifold absolute pressure sensor include poor engine performance, roughly running engine, changes in fuel consumption, and increased gas emissions. The manifold absolute pressure (MAP) sensor monitors this and reports the information to the engine's computer. If the MAP sensor starts to fail, these are some of the most common symptoms: 1. Your engine accelerates poorly: If a MAP sensor fails, it can cause the engine's computer to miscalculate the amount of fuel and ignition timing Vay Nhanh Fast Money.
