What does the Manifold Absolute Pressure (MAP) sensor measure?

The Manifold Absolute Pressure (MAP) sensor measures changes in intake manifold pressure, which is the difference between barometric pressure and manifold pressure. It helps the PCM adjust for different altitudes and controls fuel delivery and ignition timing. The PCM sends a 5 volt reference signal to the MAP sensor, and by monitoring the sensor output voltage, it can determine the manifold pressure. Testing involves comparing the voltage reading to a chart, backprobing the MAP connector, applying vacuum to the sensor, and checking the voltage between terminal C and ground. If the sensor and circuits are functional, the PCM may be faulty. To remove the MAP sensor, the intake manifold top cover is removed, the crankcase breather tube is disconnected, and the sensor is detached from the intake manifold. The MAP sensor grommet should be inspected and replaced if necessary. Installation is the reverse of the removal procedure.

Cadillac Eldorado MAP Sensor

In Cadillac Eldorado, the MAP Sensor is an important unit which gauges the positive air pressure, which enters into the intake manifold then relays to the Engine Control Unit (ECU) for the needed adjustment of fuel mixture. The fuel metering in speed-density method is managed with the help of MAP sensor that learns the air density. A MAP sensor may be used and they could also use a mass airflow sensor, and some Eldorado forced induction engines using both. The MAP sensor assists with the air mass conversation and the on-board diagnostics besides helping in precise determination of the fuel metering, ignition timings and the general performance of the car's engine.

Each OEM Cadillac Eldorado 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.
