If the circuit for the power supply is shorted to ground, the power supply will be turned off. The ECM will periodically attempt to power the circuit until the circuit is repaired.
3031-10 Intake Manifold #2 Pressure Sensor : Abnormal Rate of Change The ECM detects a value for the intake manifold pressure that is between 410 kPa (59 psi) and 520 kPa (75 psi). The pressure changes less than 1.68 kPa (0.2 psi) in 30 seconds.
The engine speed must be greater than 1000 rpm in order for this code to be set. The code is logged.
The value of the parameter will be set to 320 kPa (46 psi). System OperationThe ECM supplies a regulated voltage of 5.0 0.2 VDC to the following sensors:
Atmospheric pressure sensor
Crankcase pressure sensor
Engine coolant pump outlet pressure sensor
Filtered oil pressure sensor
Filtered fuel pressure sensor
Fuel transfer pump inlet pressure sensor
Fuel rail pressure sensor
Left intake manifold pressure sensor
Right intake manifold pressure sensor
Turbocharger 1 compressor inlet pressure sensor
Turbocharger 2 compressor inlet pressure sensor
Turbocharger 3 compressor inlet pressure sensor
Turbocharger 4 compressor inlet pressure sensor
Unfiltered fuel pressure sensor
Unfiltered oil pressure sensorThe ECM supplies a regulated voltage of 8.0 0.4 VDC to the following sensors:
Ambient air temperature sensor
Sensor for the left turbocharger turbine inlet temperature
Sensor for the right turbocharger turbine inlet temperatureThe supply voltage for the sensors is routed from the ECM to terminal 1 of each sensor connector. The sensor return for the sensors is routed from the ECM to terminal 2 of each sensor connector. The ECM provides short circuit protection for the internal power supply. A short circuit to the battery will not damage the internal power supply.-10 Codes - This code indicates that the 5 V supply is not present in the circuit for the suspect pressure sensor. The engine must be running in order for this code to become active. During normal engine operation, the actual system pressures will fluctuate slightly. When the 5 V supply is providing power to the suspect pressure sensor, the signal from the pressure sensor goes to a midrange value. This signal will not fluctuate. If the signal from the pressure sensor remains abnormally steady for more than 30 seconds, the ECM activates this code. A snapshot is triggered. The ECM sets the value of the suspect sensor to the sensor default value. Refer to Table 1 for the default values that are for the particular sensor.Note: The sensors are not protected from overvoltage. A short from the supply line to the +Battery may damage the sensors. If the diagnostic code 41-3 or the diagnostic code 2131-3 is logged, it is possible that all of the sensors on the circuit have been damaged. Repair the circuit for the sensor supply. As a precaution, replace the sensors that may have been damaged.
