These are not direct injector wires. They are trigger signals sent to the EDU, which then fires the injectors. 3. Vital Engine Sensors
explain how the ECU processes signals for idle speed and fuel injection timing. Model-Specific Guides : Specialized guides are available for the
This is where you probe for signal voltages (typically 0.5V to 4.5V).
: Unlike older diesels, the 2KD-FTV uses an Electronic Driving Unit (EDU) to fire injectors. A good diagram shows the high-voltage signals between the ECU and the EDU.
Use the Denso 89661-0K120 guide above as your baseline. Verify power, ground, and 5V reference with a multimeter. And when in doubt, pay Toyota for 24-hour access to their TIS system—it will save you 10 hours of chasing a phantom short circuit.
