Toyota Harrier ASU60/ASU65 Throttle Body Wiring Diagram

[Roland.O]

This OEM diagram gives the complete circuit tracks, wire colour codes and connector pinouts for the D23 plug assembly. It enables you to precisely test sensor reference voltage supply drops, test actuator motor lines and isolate electrical line faults from actual mechanical plate restrictions. Without it, you risk making pinning mistakes on the sensitive D23 sensor loop which can damage data network lines and the ECM.

Common questions that this document answers​

1. What is the pinout chart for the throttle body D23 connector on a Toyota Harrier ASU60/ASU65?
2. How do I test the throttle actuator motor circuit on a Toyota Harrier ASU60/ASU65?
3. What are the wire colours for the dual throttle position sensor harness on a Toyota Harrier 8AR-FTS engine?
