Intake Manifold Pressure Sensor (IMP): Rationality Monitor This OBD rationality monitor for the Intake Manifold Pressure sensor evaluates the plausibility of the sensor comparing the Barometric, Intake Air and Crankcase pressure sensor values. This evaluation is performed in two scenarios: Pre Cranking: A comparison of pressures from all sensors is made. The smallest difference between the three is determined and a reference pressure is calculated. The Intake Manifold pressure sensor value is compared to the reference value and if the difference is above the threshold a DTC is reported. Engine Running: The engine running sensor evaluation is similar to the Pre Cranking sensor evaluation. The enable conditions are defined when the vehicle is typically at idle when Barometric and Crankcase pressure are similar to Intake Manifold pressure.
