DTC P1532 Subaru

Description

Case 1 Sensor Supply Voltage A failure is detected if the external sensor supply voltage is out of the 5.0±0.1V for more than 50ms. Case 2 Pressure Sensor Signal A failure is detected if the output voltage is in the lower fault area ( 0.0V lt; pressure sensor output voltage lt; 0.25V ) for 0.1s. A failure is detected if the output signal is in the upper fault area ( 4.75V lt; pressure sensor output voltage lt; 5.0V ) for 0.1s and a positive signal step of Δoutput signal gt; 46.0 V s was detected. A failure is detected if the output signal is in the upper fault area ( 4.75V lt; pressure sensor output voltage lt; 5.0V ) for 0.5s and no positive signal step was detected. A failure is detected if the output signal is in the upper fault area ( 4.75V lt; pressure sensor output voltage lt; 5.0V ) for 60s and the output voltage of the redundant pressure sensor is higher than 2.8 V.
