Throttle Valve Opening Signal Circuit Check
- Ensure ignition is off. Disconnect harness connector at CC ECU. Turn ignition on. Using voltmeter, check voltage between ground and CC ECU harness connector terminal No. 2 (Pink/Blue wire) while opening and closing the throttle. SeeFigure . Voltage should vary as throttle is opened and closed.
- If voltage does not vary with opening and closing of throttle, check fuses, wiring and harness connectors. See appropriate wiring diagram under WIRING DIAGRAMS . Replace fuses, repair wiring or harness connectors as necessary.
