3-46 FUEL SYSTEM (DFI)
Vehicle-down Sensor (Service Code 15)
Vehicle-down Sensor Output Voltage Inspection
Remove the vehicle-down sensor.
Connect the measuring adapter [A] to the vehicle-down
Special Tool - Measuring Adapter: 57001-1700
Main Harness [B]
Vehicle-down Sensor [C]
Connect a digital meter [D] to the measuring adapter
Vehicle-down Sensor Output Voltage
Connections to Adapter:
Digital Meter (+) → W (sensor BK/BL) lead
Digital Meter (–) → BK (sensor G/P) lead
Hold the sensor vertically.
Measure the output voltage with the engine stopped, and
with the connector joined.
Turn the ignition switch on.
Tilt the sensor 65° or more [A] right or left, then hold the
sensor almost vertical with the arrow mark pointed up [B],
and measure the output voltage.
With sensor tilted 65° or more right or left:
DC 3.7 ∼ 4.4 V
With sensor arrow mark pointed up: DC
0.4 ∼ 1.4 V
Turn the ignition switch off.
If the reading is out of the standard, replace the sensor.
