With the ignition on, the module performs internal tests on the input
signal from the Pressure Sensor.
Set Condition:
This DTC will set if the input signal from the Pressure Senor is more than
240 A/D counts for Pressure Sensor Stuck High or 249 A/D counts for Pressure Sensor
Short to Ground.
PASSENGER PRESSURE SENSOR SHORT TO BATTERY
When Monitored:
With the ignition on, the module performs internal tests on the input
signal from the Pressure Sensor.
Set Condition:
This DTC will set if the input signal from the Pressure Sensor is less than
A/D counts.
PASSENGER PRESSURE SENSOR SHORT TOGETHER
When Monitored:
With the ignition on, the module performs internal tests on the input
signal from the Pressure Sensor.
Set Condition:
This DTC will set if the module determines that any one of the three input
lines to the Pressure Sensor has the same value as another line. This fault will often be set
with the Short to Ground, Short to Battery, and Open faults DTCs.
