About Dade Manifold Absolute Barometric Pressure Map
Important Notice: For Fitment, please check the compatibility OEM Part number before purchase.

As atmospheric pressure inside an intake manifold is negative during vehicle operation, the sensor is actually measuring vacuum. The ECM calculates proper air/fuel ratios, idle speeds and ignition spark timing based in part on the Manifold Absolute Pressure Sensor's signal. A malfunctioning or inoperative Manifold Absolute Pressure Sensor can cause drivability symptoms such as hard starting, stalling, harsh or poor transmission shift points, rough idle and hesitation. It can also cause the Check Engine Light (CEL), Service Engine Soon (SES) or Malfunction Indicator Lamp (MIL) to illuminate and can set a trouble code (P-code) in the ECM when not functioning correctly. Not correcting a failed Manifold Absolute Pressure Sensor condition can cause reduced fuel mileage and performance, increased emissions and damage to other components such as the catalytic converter.
