Toyota Harrier ASU60/ASU65 Low-Pressure Fuel Sensor Wiring Diagram

[Roland.O]

This OEM low pressure fuel sensor wiring diagram gives you the complete circuit tracks, wire colour codes and connector pinouts for the D62 plug assembly. It gives you the correct procedures to check sensor supply drops, test grounding tracks and isolate eletrical line faults from fuel pressure degradation. Without this factory layouts, you can easily damage sensors, high/low pressure pumps and the ECM.

Common questions that this diagram answers​

• What is the pinout chart for the low-pressure fuel sensor D62 connector on a Toyota Harrier ASU60/ASU65?
• How do I test the 5V reference voltage at the fuel delivery pipe sensor on a Toyota Harrier ASU60/ASU65?
• What are the wire colours for the low-side fuel pressure sensor on a Toyota Harrier 8AR-FTS engine?
• How do you isolate an electrical harness fault from a failing fuel pressure sensor when diagnosing fuel system codes for Harrier ASU60/ASU65?
