Test Note:

All symptoms listed above are diagnosed using the same tests.

The title for the tests will be PASSENGER PRESSURE SEN-
SOR OPEN.

When Monitored and Set Condition:

PASSENGER PRESSURE SENSOR OPEN

When Monitored:

With ignition on, the module monitors the Pressure Sensor signal.

Set Condition:

The DTC will set if the Pressure Sensor signal follows the reference

voltage.

PASSENGER PRESSURE SENSOR SHORT GROUND

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 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.
