Disconnect the intake air pressure sensor #2 connector and connect the measuring adapter [A] between these connectors.
[B] Main Harness [C] Intake Air Pressure Sensor #2 [D] Digital Meter
Special Tool - Measuring Adapter: 57001-1700
Intake Air Pressure Sensor #2 Output Voltage Connections to Adapter: Digital Meter (+) → Y (sensor G/W) lead Digital Meter (–) → BK (sensor BR/BK) lead
Output Voltage
Usable Range: DC 3.80 4.20 V at
standard
atmospheric pressure (101.32 kPa, 76
cmHg absolute)
NOTE
The output voltage changes according to the local atmospheric pressure.
If the reading is out of the usable range, replace the sensor.
If the reading is within the usable range, remove the ECU and check the wiring for continuity between main harness connector.
Special Tool - Hand Tester: 57001-1394
Disconnect the ECU and sensor connectors.
Wiring Continuity Inspection ECU Connector [A] ←→ Intake Air Pressure Sensor #2 Connector [B] G/W lead (ECU terminal 11) [C] BR/BK lead (ECU terminal 13) [D]
If the wiring is good, check the sensor for various vacuum (see Intake Air Pressure Sensor #1 Output Voltage Inspection).
