Test Two
- Start engine and bring to operating temperature (cooling fan comes on). Turn engine off. Disconnect air suction control solenoid valve connector. See Figure .
- Using a voltmeter, connect positive probe to Black/Yellow wire terminal and negative probe to Pink wire terminal. Start engine and check for voltage at idle, 30 seconds after starting (15 seconds on Coupe).
- If voltage is present, check for short in Pink wire between solenoid valve and ECU. If wire is okay, See ELECTRONIC CONTROL SYSTEM article in the COMPUTER CONTROLS section. If no voltage is present, replace air suction control solenoid valve.
