Absolutely speaking, MAP Sensor in Chevrolet Impala is one of the most important devices which is used to measure the positive air pressure entering into the intake manifold so that the engine control unit or ECU can position the device of fuel injection in right way. The primary function of the MAP Sensor mainly applies to the fuel injected engines and especially in the speed-density method by acting a key component in the determination of the air-fuel mixture in the combustion chamber. While naturally aspirated engines you will either find a MAP or MAF sensor, forced induction engines always incorporate both. MAP Sensor also plays a role in on board diagnostics as well as exhaust gas recirculation valve, this component is vital in giving measurements that will enable the right fuel flow to be metered and the engine performance tuned accordingly.
