I've not dealt with the code before, just reading through the FSM now to toss some suggestions out there. You've confirmed the solenoid gets 12V when the temperature is up, but where are you checking for the signal, and have you confirmed that the solenoid is actually actuating? The ECU provides a ground signal for the solenoid, so if you're reading 12V before the solenoid and just grounding it, you'll see 12V. You need to confirm if the ECU is grounding. Have you Have you also stepped through the troubleshooting procedures in the FSM? There are 3 procedures based on which symptom(s) you're seeing. An improper voltage signal is sent to ECM through swirl control valve control solenoid valve. The vacuum signal is not sent to swirl control valve under specified driving conditions, even though swirl control valve control solenoid valve is ON. The vacuum signal is sent to swirl control valve even though swirl control valve control solenoid valve is OFF. Which applies? Checked the vacuum switch?1 point
