[B] Main Harness
[C] Intake Air Pressure Sensor #2
Special Tool - Measuring Adapter: 57001-1700
Intake Air Pressure Sensor #2 Input Voltage Connections to Adapter: Digital Meter (+) → R (sensor BL) lead
Digital Meter (–) → BK (sensor BR/BK) lead
Input Voltage Standard: DC 4.75 ∼ 5.25 V
If the reading is within the standard, check the output voltage (see Intake Air Pressure Sensor #2 Output Voltage Inspection).
If the reading is out of the standard, remove the ECU and check the wiring for continuity between main harness connectors.
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] BL lead (ECU terminal 9) [C] BR/BK lead (ECU terminal 13) [D]
If the wiring is good, check the ECU for its ground and power supply (see ECU Power Supply Inspection in the Fuel System (DFI) chapter).
If the ground and power supply are good, replace the ECU (see ECU Removal/Installation in the Fuel System (DFI) chapter).
