3-68 FUEL SYSTEM (DFI)
Atmospheric Pressure Sensor (Service C ode 15)
If the output voltage is far out of the usable range, remove
the seat cover, and check the output voltage at the sensor
connector [A] (when the wiring is open, the output voltage
is about 1.8 V).
•
Connect a digital meter [A] to the harness adapter leads.
Atmospheric Pressure Sensor [B]
Special Tool - Sensor Harness Adapter: 57001-1561
Atmospheric Pressure Sensor Output Voltage
Connections to Adapter
Meter (+) → G/W (sensor G/W) lead
Meter (–) → BK (sensor BR/BK) lead
Output Voltage at Sensor
Usable Range:
DC 3.80 ∼ 4.20 V at the standard
atmospheric pressure (101.32 kPa, 76
cmHg abs.)
•
Turn the ignition switch OFF.
If the output voltage is normal, check the wiring for conti-
nuity (see wiring diagram in this section).
If the output voltage is out of the usable range, replace
the sensor.

If you need to check the atmospheric pressure sensor for
various altitudes other than sea level, check the output
voltage as follows:
