Chevrolet Express MAP Sensor

Chevrolet Express MAP Sensor supplies the engine computer with exact manifold pressure information to allow the ECU to control the fuel and spark in relation to actual flow. By converting absolute pressure to a rapid electrical signal, the MAP Sensor helps the speed density strategy followed by many vans rather than a mass airflow meter. When rpm goes up or vacuum drops, the sensor reacts immediately, allowing injectors to stay on time and avoiding a stumble or wasted fuel. Naturally aspirated versions of the Express use one MAP Sensor with an intake air temperature probe to determine air mass, with boosted trims using the same unit alongside a mass airflow sensor for more precise control. Later OBD II years retained the same small plastic piezoresistive core but included more intelligent circuitry to allow the ECU to test the EGR valve and record any faults more quickly. A failed MAP Sensor can cause an error and make many Chevrolet drivers feel lazy throttle response. Consistent voltage sweeps from the MAP Sensor keep fuel trims tight on steep grades, letting Chevrolet reliability shine through every Express mile.

Each OEM Chevrolet Express MAP Sensor we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
