Toyota Harrier ASU60/ASU65 Air Fuel Ratio Sensor Wiring Diagram

[Roland.O]

This factory wiring diagram is critical for circuit tracing, power and ground verification and for pinpointing signal paths for the Air Fuel Ratio Sensor connector D35. It provides you with the precise connections needed to execute terminal-level voltage and resistance testing on the sensor's heater circuit and reference lines to the engine ECU. Any attempts to troubleshoot an air to fuel ratio circuit without the OEM schematics is extremely risky since any small mistep can destroy the ECM.

Common questions that this diagram answers​

1. What is the pinout chart for the Toyota Harrier ASU60/ASU65 air-fuel ratio sensor D35 connector?
2. How do I check for proper voltage supply at the Toyota Harrier ASU60/ASU65 A/F sensor heater?
3. What are the wire colours for the 8AR-FTS engine air-fuel ratio sensor on a Toyota Harrier?
4. How do you diagnose a signal circuit fault at the D35 sensor plug without destroying the ECM?
